What is the typical speed limit on a US Interstate highway in most states?
- 65 to 75 mph, with some western states allowing 80 mph or higher ✓
- There is no speed limit on Interstates
- 55 mph
- Always 70 mph
Interstate speed limits vary by state and by specific road section. Most US states post Interstate limits in the 65-75 mph range. Some western states allow 80 mph on rural Interstates (Texas, Utah, Idaho, Montana, Wyoming, Nevada, South Dakota). Texas has a 85 mph posted limit on some rural toll roa… Full explanation →
-
What is the speed limit in a residential area or business district when no limit is posted?
- There is no default; you can drive any speed
- 55 mph
- Typically 25-35 mph depending on state default rules ✓
- 70 mph
When no speed limit is posted, every state has 'default' or 'absolute' limits based on the road type. Typical defaults: 25 mph in business and residential districts (some states 30 or 35); 55-65 mph on rural highways; 65-70 mph on Interstates. School zones during posted hours are typically 15-25 mph… Full explanation →
-
What does a yellow advisory speed sign on a curve mean?
- A recommended safe speed for the upcoming curve under normal conditions, not a legal limit (which would be in black-on-white) ✓
- The speed at which to start braking
- A minimum speed
- A maximum legal speed limit
Yellow advisory speeds (typically square or diamond yellow signs with a speed number) are recommendations for navigating an upcoming curve, ramp, or hazard. They are not legal limits in the same way black-on-white speed limit signs are — but driving above the advisory speed and crashing is strong ev… Full explanation →
-
At a T-intersection where one road ends at another, which driver has the right of way?
- Always the driver on the smaller road
- Both yield equally
- Whoever arrives first
- The driver on the through road (the one that does not end); the driver on the terminating road must yield ✓
At a T-intersection, the road that does not terminate is the 'through' road, and traffic on it has the right of way. The driver on the road that ends at the intersection must yield to all traffic on the through road before turning. This rule applies whether the terminating road has a stop sign (whic… Full explanation →
-
When you enter an Interstate from an entrance ramp, you should:
- Drive slowly until you reach the right lane
- Force your way in
- Use the acceleration lane to reach a speed matching Interstate traffic, signal, find a safe gap, and merge — yielding to traffic already on the Interstate ✓
- Stop and wait for Interstate traffic to clear
Entering an Interstate is the responsibility of the merging driver, not the Interstate traffic. Use the on-ramp's acceleration lane (also called the 'merge lane') to bring your speed up to match prevailing Interstate traffic — usually 60-70 mph. Signal early, check mirrors and blind spots, find a sa… Full explanation →
-
When making a right turn at a red light (where permitted), you must:
- Slow down and proceed without stopping
- Come to a complete stop, yield to all traffic and pedestrians, and proceed only when safe — unless a sign prohibits right on red ✓
- Honk and turn
- Wait for the light to turn green
Most states allow a right turn on red after coming to a complete stop and verifying it is safe — but several specific conditions apply: come to a complete stop (rolling stops are illegal and frequently ticketed); yield to all approaching traffic from the left; yield to pedestrians in the crosswalk; … Full explanation →
-
Some states allow a left turn on red. When is this permitted?
- Only at flashing lights
- Never — left on red is always illegal
- Always
- From a one-way street onto another one-way street where traffic on the destination street moves to the right — after a complete stop and yielding to all traffic, in states that allow this rule ✓
Most US states permit a left turn on red only when both the street you are leaving and the street you are entering are one-way streets where the destination street's traffic moves to the right (in your direction). After a complete stop and yielding to all traffic and pedestrians, the left turn is al… Full explanation →
-
When making a left turn, you should:
- Cross over multiple lanes during the turn
- Begin from the rightmost lane
- Begin from the leftmost lane that allows left turns, signal in advance, yield to oncoming traffic, and complete the turn into the leftmost lane available going in your new direction ✓
- Turn only at green arrows
Left turn procedure: position your vehicle in the leftmost lane that permits left turns (which may be a dedicated turn lane or the leftmost through lane); signal at least 100 feet in advance (more on highways); come to a stop if required or yield to oncoming traffic if turning across opposite-direct… Full explanation →
-
On a multi-lane highway, when should you use the leftmost lane?
- When passing slower traffic; otherwise drive in the right or middle lanes ('keep right except to pass' rule) ✓
- For all normal driving
- Only between exits
- Whenever you are in a hurry
The 'keep right except to pass' rule is the standard for multi-lane highway driving in every state. The right lane is for normal driving; left lanes are for passing. After completing a pass, return to the right or middle lane. Some states actively enforce left-lane camping with fines. The reason: la… Full explanation →
-
What is a 'high occupancy vehicle' (HOV) lane?
- A lane only for emergency vehicles
- A standard lane with no special rules
- A lane only for trucks
- A lane restricted to vehicles carrying a minimum number of occupants (typically 2 or 3) during posted hours, intended to encourage carpooling ✓
HOV lanes (also called 'carpool lanes' or 'diamond lanes' from the painted diamond markings) are restricted to vehicles with a specified minimum number of occupants — typically 2+ or 3+ depending on the road and time of day. The restriction usually applies during rush hours; outside posted hours the… Full explanation →
-
How close to a fire hydrant may you park?
- Most states prohibit parking within 15 feet of a fire hydrant ✓
- Within 5 feet only
- There is no rule
- Right next to it
Most US states prohibit parking within 15 feet of a fire hydrant. The reason is critical: fire trucks need clear access to connect hoses to hydrants in an emergency, and a parked vehicle blocking access can mean the difference between containing a fire and losing a building or lives. Penalties for h… Full explanation →
-
What does a red curb typically indicate?
- Permit parking only
- Free parking
- No parking or stopping at any time ✓
- Loading zone
Curb painting is generally standardized across most US states: red means no parking or stopping at any time (often near fire hydrants, intersections, or emergency access points); yellow means commercial loading and unloading only, often with time restrictions; white means passenger loading and unloa… Full explanation →
-
When parking on a hill facing uphill with a curb, you should:
- Turn the front wheels toward the curb
- Wheel direction does not matter
- Turn the front wheels away from the curb (toward the road) so if the vehicle rolls, it rolls backward into the curb and stops ✓
- Turn the wheels straight
When parked facing uphill with a curb, turn the front wheels away from the curb. The reasoning: if the vehicle rolls backward (the most common rolling direction when parked uphill), the rear of the vehicle drifts toward the curb on its own; the front wheels turned away from the curb mean the vehicle… Full explanation →
-
When approaching a stopped school bus with red flashing lights and stop arm extended on a two-lane road, you must:
- Honk and continue
- Slow down only
- Continue at normal speed
- Stop and remain stopped in both directions until the red lights turn off and the stop arm retracts; this protects students who may be crossing the road ✓
On a two-lane or undivided road, all traffic in both directions must come to a complete stop when a school bus has red flashing lights and the stop arm extended. Students may be crossing the road in either direction to reach the bus or their destination, and the school bus driver's signaling system … Full explanation →
-
On a divided highway (with a physical median or barrier), what is required when a school bus stops with red lights flashing in the opposite direction?
- All traffic in both directions must stop
- All traffic must stop on every type of road
- Only school buses must stop
- Generally, only traffic in the same direction as the bus must stop; traffic on the opposite side of a divided highway may continue with caution (state laws vary) ✓
On a divided highway with a physical median or barrier, most states require only traffic in the same direction as the bus to stop. Traffic on the opposite side of the barrier is presumed to be separated from any crossing students by the physical median. State laws vary on what counts as a 'divided' … Full explanation →

How quickly must you update your driver's license address after moving?
- Update is optional
- Most states require notification within 10 to 30 days of moving ✓
- Only when the license expires
- Within 1 year
Every US state requires drivers to update their license address within a specified time after moving — typically 10 to 30 days. Failure to update can result in fines and complications with insurance and vehicle registration. Some states allow online address updates; others require an in-person visit… Full explanation →
-
What should you do if a police officer signals you to pull over?
- Roll up all windows and lock the doors
- Speed up to get away
- Pull over to the right shoulder safely and as soon as practical, stop the engine, keep your hands visible on the steering wheel, and follow the officer's instructions ✓
- Continue driving until you reach your destination
When signaled to pull over: signal your intent to pull over, slow down, and move to the right shoulder as soon as practical and safe. Stop the engine. Roll down the driver's window. Keep your hands visible on the steering wheel — typically at the 10-and-2 position — and do not reach for the glove co… Full explanation →
-
Are you required to carry your driver's license while driving?
- Only on highways
- Only on weekdays
- Yes, every state requires drivers to carry their valid license and produce it on demand to law enforcement ✓
- No, it is optional
Every US state requires drivers to carry their valid driver's license whenever they are operating a motor vehicle. Failure to produce the license on demand is generally a citable offense, though usually a minor one ('failure to display') that can be dismissed by proving you held a valid license at t… Full explanation →
-
Is auto insurance required to drive a vehicle on public roads in the US?
- Only in cities
- Yes, every state except (essentially) New Hampshire requires drivers to maintain liability insurance or equivalent financial responsibility; minimums vary by state ✓
- No, insurance is always optional
- Only for commercial vehicles
Every US state except New Hampshire requires drivers to maintain auto liability insurance or equivalent financial responsibility (a cash bond or self-insurance for those with substantial assets). New Hampshire requires drivers to be able to demonstrate financial responsibility if they cause a crash,… Full explanation →
-
If you are involved in an accident, what should you do?
- Continue driving and report later
- Only call your spouse
- Drive away if no one appears injured
- Stop, check for injuries, exchange information with the other driver (name, address, license, insurance, plate), report the accident to police if required, notify your insurer ✓
Required steps after an accident: stop at the scene (leaving the scene of an accident is a serious crime — 'hit and run'); check for injuries and call 911 if anyone is hurt; exchange information with other drivers including name, address, driver's license number, insurance company and policy number,… Full explanation →
-
When a school bus stops on a multi-lane undivided road (3+ lanes), what should drivers do?
- Only the lane next to the bus must stop
- All lanes in both directions must stop, just as on a two-lane road; the lack of a physical median means students may cross all lanes ✓
- Continue at normal speed
- Slow down only
An undivided road, regardless of how many lanes it has, requires all traffic in both directions to stop for a stopped school bus with red lights flashing and stop arm extended. The principle: without a physical median to separate directions, students may need to cross all lanes to reach their destin… Full explanation →
-
What is the meaning of a green arrow traffic signal?
- Stop
- Slow down
- Protected turn — proceed in the direction of the arrow without yielding (oncoming traffic has a red light) ✓
- Yield to oncoming traffic
A solid green arrow indicates a protected turn — oncoming traffic in conflicting directions has a red light, and the driver may proceed in the direction the arrow points without yielding (still yielding to pedestrians in the crosswalk). A flashing yellow arrow indicates that turning is permitted but… Full explanation →
-
If you are in a lane that ends ('lane drop'), you should:
- Drive on the shoulder
- Stop in the lane
- Signal early, move into the adjacent open lane when safe, and merge well before the lane physically ends ✓
- Force your way into the next lane at the last moment
When your lane is ending (a 'lane drop'), the responsible behavior is to: identify the lane drop early (signs typically warn 1/2 mile and again 1/4 mile ahead); signal early; check for a gap in the adjacent lane; merge smoothly while there is still plenty of road remaining. The 'zipper merge' techni… Full explanation →
-
What is the minimum speed law on most US highways?
- 20 mph below the maximum
- Half the posted maximum
- Most state laws require driving at a 'reasonable speed for conditions' — slow drivers (often 20+ mph below the limit) can be cited for impeding traffic if they have no good reason ✓
- There is no minimum
Most US highways do not have a posted minimum speed but state laws generally require driving at a reasonable speed for conditions and prohibit impeding traffic without good cause. Some Interstates post a minimum speed (typically 40-45 mph) for vehicles that cannot maintain prevailing traffic speeds.… Full explanation →
-
At an uncontrolled intersection (no signs or signals), who has the right of way?
- The driver who got there first; if simultaneous, the driver on the left yields to the driver on the right ✓
- Nobody — you must wait indefinitely
- Whoever has the larger vehicle
- The driver who got there first; if simultaneous, the driver on the right yields to the driver on the left
At an uncontrolled intersection (no stop, yield, or signal), the basic rules are: the driver who arrives first has the right of way; if two vehicles arrive simultaneously, the driver on the left yields to the driver on the right; if a driver is making a left turn while another is going straight or t… Full explanation →
-
At a 4-way stop, two vehicles arrive simultaneously — one from the north and one from the east. Who has the right-of-way?
- The vehicle from the east, because the driver on the LEFT yields to the driver on the RIGHT — in this case, the north-facing driver has the east-facing driver on their RIGHT, so the east-facing driver goes first ✓
- The vehicle from the north, because north is top of the map
- The vehicle that is turning, because they have a more complex maneuver
- Whoever signals first
4-WAY STOP TIE-BREAKER — YIELD TO THE RIGHT: When vehicles arrive simultaneously at a 4-way stop, the driver on the LEFT must yield to the driver on the RIGHT. Visualise: North-facing driver looks to their right and sees the east-facing driver — they yield. East-facing driver looks to their right an… Full explanation →
-
A pedestrian is in the middle of an unmarked crosswalk at an intersection. A driver wants to turn right. Who has the right-of-way?
- Whoever makes eye contact first
- The driver turning right, since they have a green light
- The pedestrian — pedestrians always have the right-of-way in crosswalks (marked or unmarked); drivers must yield even on a green light if a pedestrian is in or about to enter the crosswalk ✓
- First to arrive at the intersection
PEDESTRIAN RIGHT-OF-WAY: Pedestrians have right-of-way in crosswalks — both MARKED (painted stripes) and UNMARKED (the implied crosswalk that exists at every intersection regardless of paint). DRIVER MUST YIELD: When a pedestrian is in a crosswalk; when a pedestrian is about to enter — many states r… Full explanation →
-
How far from a fire hydrant must a vehicle be parked to be legally parked in most states?
- 50 feet
- 15 feet ✓
- 5 feet
- 25 feet
FIRE HYDRANT PARKING: In most states, you must park at least 15 feet from a fire hydrant. Why: fire trucks need room to access the hydrant and connect hoses; a car within 15 feet blocks access; in a fire emergency, firefighters will break car windows to run hoses through the vehicle if necessary (th… Full explanation →
-
What is the 'move over law' and when does it apply?
- Only for police vehicles
- Move over when any driver signals you are going too slow
- Only on the highway, not city streets
- Move over one lane (or slow down significantly if lane change is unsafe) when approaching emergency, police, fire, tow trucks, or road maintenance vehicles stopped on or near the road with warning lights activated ✓
MOVE OVER LAW: All 50 states have move-over laws. REQUIREMENT: When approaching a stationary emergency, police, fire, ambulance, tow truck, or road maintenance vehicle with warning lights activated — if possible, move one full lane away from the stopped vehicle; if lane change is not safely possible… Full explanation →
-
On a two-way street, in which direction should your wheels be turned when parking uphill WITH a curb?
- Turn wheels LEFT (away from the curb) — if your parking brake fails or the car rolls, the front wheel will catch the curb and stop the car from rolling into traffic ✓
- It doesn't matter for uphill parking
- Straight ahead
- Turn wheels RIGHT (toward the curb)
HILL PARKING — the four scenarios: UPHILL + CURB: Turn wheels LEFT (away from curb); if car rolls backward, the right rear will drift left and the front wheels will catch the curb. DOWNHILL + CURB: Turn wheels RIGHT (toward curb); if car rolls forward, the front wheels will hit the curb. UPHILL, NO … Full explanation →
-
When is it legal to drive in the left lane of a multi-lane highway?
- The left lane is for trucks only
- Only when the right lane is congested
- When passing another vehicle or when traffic conditions require it — many states have 'keep right' laws that require slower traffic to stay in the right lanes; the left lane is for passing or faster-moving traffic ✓
- Always — any driver can use any lane at any time
KEEP RIGHT / LEFT LANE LAWS: Most states have laws requiring slower-moving traffic to stay in the right lane on multi-lane highways. The left lane is designated for: PASSING slower vehicles; FASTER-MOVING TRAFFIC in some areas; LEFT TURNS. In some states, a 'KEEP RIGHT EXCEPT TO PASS' sign makes the… Full explanation →

- Immediately pull to the RIGHT side of the road and stop — allow the emergency vehicle to pass ✓
EMERGENCY VEHICLE RIGHT-OF-WAY: REQUIRED BY LAW: All drivers must immediately yield the right-of-way to emergency vehicles using sirens and/or flashing lights (police, fire, ambulance). PROCEDURE: Signal and pull to the RIGHT edge of the road; stop completely; remain stopped until the emergency vehi… Full explanation →
-
At what blood alcohol concentration (BAC) does the law typically consider a commercial driver legally impaired?
- 0.02%
- 0.08% (same as non-commercial drivers)
- 0.04% — commercial drivers (CDL holders) are held to a stricter standard because they operate larger, more dangerous vehicles and drive professionally ✓
- 0.10%
COMMERCIAL DRIVER ALCOHOL LIMITS: BAC 0.04% is the legal limit for CDL holders operating commercial vehicles — half the standard adult limit of 0.08%. WHY STRICTER: Commercial vehicles weigh up to 80,000 lbs; stopping distances are much longer; the consequences of crashes are more severe; commercial… Full explanation →
-
When is a U-turn generally legal?
- Where there is no 'NO U-TURN' sign, where the driver can see clearly in all directions for a safe distance, and where local law permits — U-turns are prohibited at intersections controlled by traffic signals in many jurisdictions unless specifically signed as permitted ✓
- U-turns are always legal
- Only at traffic lights
- Whenever traffic permits
U-TURN LEGALITY varies by state and location: GENERALLY PROHIBITED: At intersections controlled by traffic signals in many states; where a 'NO U-TURN' sign is posted; in business districts (unless specific allowance); near a fire station, school, or pedestrian crosswalk; where visibility is limited … Full explanation →
-
What is 'implied consent' and what does it mean for drivers?
- A driver consents to follow all traffic laws by getting a licence
- Drivers imply their consent by being courteous on the road
- Consent is implied for police to search your vehicle
- By obtaining a driver's licence, a driver has implicitly consented to chemical testing (breath, blood, or urine) for alcohol or drugs when lawfully requested by law enforcement — refusing the test results in automatic licence suspension regardless of whether the driver was actually impaired ✓
IMPLIED CONSENT LAW: In all 50 states, a driver who operates a motor vehicle on public roads has implicitly consented to chemical testing for alcohol or drugs as a condition of having a licence. WHAT THIS MEANS IN PRACTICE: If a law enforcement officer has probable cause to believe you are driving u… Full explanation →
-
Two vehicles arrive at a four-way stop simultaneously. Vehicle A is going straight; Vehicle B is turning left. Vehicle B is to Vehicle A's right. Who has the right of way?
- Both can proceed simultaneously
- Whoever honks first has the right of way
- Vehicle B because it arrived at the same time and is to the right
- Vehicle A has the right of way for two reasons: (1) Vehicle B is turning left and must yield to oncoming straight-through traffic; (2) Even with the 'right rule' applying, a turning left vehicle must still yield to straight-through traffic ✓
FOUR-WAY STOP TIE-BREAKING: When two vehicles arrive SIMULTANEOUSLY, the vehicle on the RIGHT has the right of way over the vehicle on the LEFT. BUT: This rule applies between vehicles going the same direction of travel or both going straight. THE TURN RULE OVERRIDES: A vehicle turning left must ALW… Full explanation →
-
The 3-second following distance rule — how do you apply it?
- Follow 3 car lengths behind
- Count to 3 before accelerating from a stop
- Choose a fixed object ahead (sign, tree, overpass); when the vehicle in front passes it, begin counting seconds; your vehicle should not reach the same object until you have counted at least 3 seconds — if less than 3, you are following too closely ✓
- Count 3 seconds while changing lanes
3-SECOND FOLLOWING DISTANCE TEST: PROCEDURE: Pick a fixed roadside marker (sign, overpass, line on road) when it's dry, light conditions at normal speed; Note when the rear of the vehicle ahead passes it; Count 'one-thousand-one, one-thousand-two, one-thousand-three' at a steady rate; Your front bum… Full explanation →
-
A driver is stopped at a red light and wants to turn right. There is a sign: 'NO TURN ON RED.' What must the driver do?
- Proceed through the red light to clear traffic
- Turn right after a brief stop
- Wait for the green light before turning — 'NO TURN ON RED' signs are regulatory signs that prohibit turning at red lights; the sign overrides the general rule that right turns on red are permitted after stopping ✓
- Turn right only if no traffic is visible
RIGHT TURN ON RED (RTOR): GENERAL RULE: In the US, right turns on red are permitted after a complete stop, yielding to pedestrians and cross traffic, EXCEPT when prohibited by a sign or pavement marking; NO TURN ON RED SIGN: Located at intersections where RTOR is prohibited — often due to pedestrian… Full explanation →
-
Under what circumstances may a driver cross a solid yellow centre line to pass?
- Only on two-lane roads with no centre line
- A solid yellow line on YOUR side of the centre means no passing — you may NEVER cross a solid yellow centre line on your side to pass, regardless of traffic conditions ✓
- Whenever traffic is clear
- Only if the other vehicle is driving slowly
YELLOW CENTRE LINE MEANING: SINGLE SOLID YELLOW: Marks the centre of a two-way road; DOUBLE SOLID YELLOW: Absolute no-passing zone in BOTH directions; DASHED YELLOW: Passing permitted when safe (the dashes are on your side when passing is allowed from your direction); SOLID/DASHED COMBINATION: The s… Full explanation →
-
A driver is on a highway on-ramp preparing to merge. What is the proper merging technique?
- Merge as slowly as possible to force cars to make room
- Turn on hazard lights and merge regardless
- Signal early; match the speed of highway traffic while still on the on-ramp; find a gap in traffic; merge smoothly at highway speed — do not stop on the on-ramp unless absolutely necessary; yield to highway traffic ✓
- Stop at the end of the on-ramp and wait for a gap
HIGHWAY MERGING TECHNIQUE: The on-ramp is an ACCELERATION LANE — use its full length to match highway speed; STEPS: Signal your intent to merge early; accelerate to match highway traffic speed; look for a gap (check mirrors, blind spot); merge smoothly into the gap; cancel signal; do not stop at the… Full explanation →
-
A driver hears a siren and sees flashing red and white lights approaching from behind. What is required?
- Immediately pull to the right side of the road and stop — federal and state law requires all drivers to yield to emergency vehicles (police, fire, ambulance) by pulling right and stopping until the emergency vehicle passes; this is required in every US state ✓
- Maintain current speed and lane
- Only slow down if the vehicle is directly behind you
- Move to the left lane
YIELD TO EMERGENCY VEHICLES: All states require: PULL TO THE RIGHT side of the road; STOP as far from the travel lane as safely possible; REMAIN STOPPED until the emergency vehicle has passed and it is safe to resume; NEVER BLOCK AN INTERSECTION — if approaching an intersection and an emergency vehi… Full explanation →
-
A driver parks on a hill facing uphill with a curb on the right. Which direction should the front wheels be turned?
- Straight ahead
- Toward the curb (right)
- Away from the curb (toward the street) — if the car rolls backward due to brake failure, the right front wheel hits the curb and stops the vehicle from rolling into traffic ✓
- Direction doesn't matter on uphills
HILL PARKING WHEEL DIRECTION — UPHILL WITH CURB: Turn wheels AWAY from the curb (to the LEFT, toward the road/traffic). LOGIC: If the car rolls BACKWARD, the right-rear of the car goes toward the curb; the wheel turned LEFT means the left front wheel is pointing toward the road, but the back of the … Full explanation →
-
A driver wants to make a U-turn. Which of the following locations is a U-turn typically prohibited?
- Only when other cars are present
- On a straight road with no traffic
- Only on divided highways
- In front of a post office, bank, or within 200 feet of an intersection, on a curve, near a hill crest, in a school zone, or where a sign prohibits it — U-turns are also prohibited where the turn cannot be completed safely without interfering with other traffic ✓
U-TURN PROHIBITIONS: State laws vary but common prohibited locations include: Where a 'NO U-TURN' sign is posted; Near the crest of a hill (limited visibility); On a curve (limited visibility); In a school zone; Within a set distance of an intersection, railroad crossing, or signal (varies: 200-500 … Full explanation →

When driving at night, when should a driver switch from high beams to low beams?
- When street lights are present
- When an oncoming vehicle is within approximately 500 feet (150 metres) AND when following another vehicle within 300 feet (90 metres) — high beams can blind oncoming drivers and reflect off mirrors blinding the driver ahead ✓
- Never — high beams are always better at night
- Only in city driving
HIGH BEAM ETIQUETTE AND LAW: ONCOMING TRAFFIC: Dim to low beams when an oncoming vehicle is within 500 feet (varies by state: 300-500 feet) — high beams directly into an oncoming driver's eyes cause temporary blindness (glare); the affected driver cannot see for several seconds after the bright ligh… Full explanation →
-
A driver has a blood alcohol content (BAC) of 0.03% — below the 0.08% legal limit. Is it safe to drive?
- No — alcohol begins affecting driving ability at much lower levels than 0.08%; at 0.03-0.05% BAC, studies show reduced coordination, divided attention, and increased lane deviation; the legal limit does not equal the safe limit ✓
- Only unsafe for novice drivers
- Yes — they are below the legal limit so they are not impaired
- Yes — 0.03% has no effect on the brain
LEGAL LIMIT ≠ SAFE LIMIT: Research on driving performance and alcohol: 0.01-0.03%: Some measurable effects on reaction time and divided attention begin for some individuals; 0.03-0.05%: Reduced coordination; slightly reduced ability to track moving objects; increased lane variation; 0.05-0.07%: Stee… Full explanation →

What does a solid yellow line on your side of the road's center line mean?
- You may NOT pass — do not cross a solid yellow line on your side to pass ✓
- The road is closed
- Parking is allowed
- You may pass freely
A SOLID YELLOW line on YOUR side of the center line means you may NOT PASS (do not cross it to pass another vehicle). DMV/permit rules of the road. CENTER LINE MARKINGS: a BROKEN (dashed) yellow line on your side means passing IS allowed when safe; a SOLID yellow line on your side means NO passing. … Full explanation →

When an EMERGENCY VEHICLE approaches with flashing lights and/or siren, you must PULL OVER to the RIGHT edge of the road and STOP, yielding the right-of-way and letting it pass; remain stopped until it has passed. DMV/permit rules of the road. EXCEPTIONS/NOTES: if you're in an intersection, clear th… Full explanation →
-
What does the 'basic speed law' require of drivers, regardless of the posted limit?
- Always drive at the posted limit
- Drive as fast as traffic allows
- The posted limit is only a suggestion
- Never drive faster than is safe for the current conditions, even if that is below the posted limit ✓
The basic speed law requires that you never drive faster than is reasonable and safe for the existing conditions — traffic, weather, visibility, and road surface — regardless of the posted speed limit. The posted limit is the maximum under ideal conditions, not a guarantee that the limit is always s… Full explanation →
-
Who has the right of way at an uncontrolled intersection (no signs or signals) where two cars approach at the same time?
- The faster car
- The larger vehicle
- The driver on the left yields to the driver on the right ✓
- Whoever entered the road first that day
At an uncontrolled intersection — one with no traffic signals or signs — drivers must use the basic right-of-way rules and proceed with great caution.
