A red triangular sign with the point down means:
- Stop
- Yield: slow down, give right of way to other traffic, stop if needed ✓

A square or rectangular white sign with black text typically indicates:
- A warning of hazard ahead
- A regulatory sign — a rule you must obey, such as speed limit, no parking, or one-way ✓
- A guide sign with destination information

Black-on-white rectangular signs are regulatory: they communicate rules drivers must obey. Examples include speed limits, no parking, one-way arrows, do not enter, no turn on red, and lane use restrictions. Disobeying a regulatory sign is a traffic violation. Warning signs are typically yellow diamo…

A yellow diamond sign with two children walking means:
- Pedestrian crossing
- School zone or school crossing ahead — slow down and watch for children ✓
- Day care center

A yellow diamond with two curving arrows indicating opposite directions means:
- Crossroads ahead
- Winding road — series of curves ahead ✓
- Detour required
- Roundabout
An S-shaped or double-curve arrow on a yellow diamond warns of a winding road — a series of curves ahead, not a single curve. Reduce speed and prepare to steer through multiple bends in sequence. Single-curve signs (one arrow bending one way) warn of one curve, often with an advisory speed posted un…

Blue signs along the highway typically indicate:
- Warnings
- Motorist services like gas, food, lodging, hospitals, and rest areas ✓
- Construction
- Speed limits
Blue signs are service signs. They direct drivers to gas stations, food, lodging, hospitals, rest areas, campgrounds, and other services available at upcoming exits.

What should you do when a flagger holds out a stop or slow-paddle sign?
- Ignore them; flaggers have no authority
- Obey their instructions exactly; flaggers' directions override standard traffic rules in the work zone ✓

-
A 'No U-Turn' sign means:
- You may make a U-turn only at intersections
- You may not make a U-turn at the location of the sign ✓
- You may make a U-turn only at posted hours
- U-turns require a left signal
A circular sign showing a U-shaped arrow with a red line through it prohibits U-turns at that location. U-turns are dangerous in many places: at busy intersections, on highways, on hills with limited sight distance, where the road is too narrow to complete the maneuver safely. Where U-turns are proh…

A yellow diamond sign with the symbol of a truck on a downward slope means:
- Trucks prohibited
- Steep grade ahead; trucks should use low gear ✓
- Truck weigh station
- Truck rest area

- Red lights are not in operation
- Left turns only allowed

- The sign only applies during peak hours
'RIGHT TURN ONLY' is a REGULATORY SIGN — white background, black text. It requires the driver to turn right. It does not say 'may turn right' or 'right turns permitted.'

-
What does a white rectangular sign reading 'SPEED LIMIT 55' mean to a driver in wet weather when visibility is poor?
- The driver must drive exactly 55 mph
- 55 mph is the maximum under ideal conditions — in poor visibility or wet weather, a driver must reduce speed to what is safe and reasonable; driving at 55 in dangerous conditions can be a violation of the basic speed law even though it's at the posted limit ✓
- 55 mph is always the minimum speed on this road
- The sign only applies during daylight hours
BASIC SPEED LAW: All states have a basic (or prima facie) speed law requiring drivers to operate at a speed that is 'reasonable and prudent' for current conditions, regardless of the posted speed limit.
