Motorcycle Emergency Braking and Swerving — Practice Questions

Intersections are the highest-risk locations for motorcycles. Studies consistently show that the majority of motorcycle-vehicle crashes happen at intersections, with the most common type being a car turning left across the motorcycle's path. The driver typically reports 'I didn't see the motorcycle' — a combination of motorcycle's smaller visual profile, drivers' tendency to look for cars rather than motorcycles, and motorcycles' unexpected presence in many drivers' mental model. Defensive techniques at intersections: assume drivers do not see you; cover the brakes; ride in a lane position that maximizes visibility (often Position 3 when approaching oncoming traffic that might turn left); reduce speed and be ready to brake; make eye contact with the driver if possible.

Standard mounting procedure: approach the motorcycle from the left side (the kickstand is on the left and the bike leans that way, making mounting from the left more stable); grasp the left handlebar and either apply the front brake or hold the right handgrip; swing your right leg over the seat (over the back of the seat, not over the gas tank); settle onto the seat with both feet on the ground at first; retract the kickstand; balance with both feet down until ready to ride. Dismounting is the reverse. Most motorcycle handling habits — left-side mounting, brake-on dismounting, kickstand operation — become automatic with practice. Practice these basics in a parking lot before riding on the road.

Engine braking — using the engine's compression resistance to slow the motorcycle — is a useful technique that saves brake wear and provides better control on descents. Technique: roll off the throttle and let the engine slow the motorcycle; as speed drops, downshift smoothly to keep RPM in a useful range (about midway through the rev range, not at idle); apply brakes if additional slowing is needed. Coordinated use of engine braking and the brakes is what experienced riders use for almost all routine slowing. On long descents, engine braking prevents brake fade — the same problem CDL drivers manage on mountain grades. Pulling the clutch in completely defeats engine braking; only do that when you need to be in neutral or when shifting.

Lane splitting is the practice of a motorcycle riding between lanes of slow or stopped traffic — common in many countries but historically illegal in most US states. California has long allowed it. As of 2024, a handful of other states have legalized 'lane filtering' under more limited conditions (only at very low speeds, only when traffic is fully stopped, only between specific lanes). It remains illegal in most US states. Always check the specific law in your state and any state you ride through. Even where legal, lane splitting requires caution: drivers may change lanes unexpectedly, doors may open, and the practice surprises drivers who do not expect a motorcycle between lanes. Speed differential to surrounding traffic should be small (10-15 mph above traffic speed is the recommended maximum).

Most states issue motorcycle credentials in one of two ways: a separate motorcycle license, or an endorsement added to an existing driver's license. Requirements typically include: holding a valid driver's license or learner's permit; passing the motorcycle written knowledge test; passing either the state's motorcycle road skills test (administered by the DMV on your motorcycle) or completing the Motorcycle Safety Foundation (MSF) Basic RiderCourse — a 15-20 hour weekend course that includes classroom and range-time riding instruction. Most riders take the MSF course because it teaches the skills as well as testing them, provides motorcycles to learn on, costs less than purchasing then crashing your own bike, and produces better-prepared riders. Some states require the MSF course for riders under a certain age.

Helmet physics: OUTER SHELL (polycarbonate, fibreglass, or carbon fibre) distributes the point impact across a larger surface area, preventing skull penetration; ENERGY-ABSORBING LINER (expanded polystyrene, EPS foam) crushes progressively under impact — this controlled deformation slows the head's deceleration from crash speed to zero over a longer time and distance, dramatically reducing peak force on the brain; COMFORT LINER (cloth) — no safety function. Key principle: force = mass × acceleration (F=ma); if deceleration takes longer (helmet crushes), peak force is lower even with the same total mass and velocity change. This is why a single severe impact destroys the EPS liner — it has done its job and cannot be reused. Any helmeted crash = replace the helmet even if the exterior looks intact.

The MSF teaches: SLOW BEFORE (not during) turns. In a turn-entry-too-fast scenario: BEST OUTCOME if you still have options: get your eyes up and looking at the exit, push the handlebars (countersteering) to increase lean angle, trust the bike's capability (most riders reach pavement well before the bike reaches its lean limit), and smooth throttle/brake inputs. WHAT NOT TO DO: brake hard in mid-turn — this reduces lean angle and can cause a low-side crash; straighten up to run off the road — typically causes a higher-speed impact with obstacles off-road than completing the turn. PREVENTION: slow enough BEFORE the turn that you can complete it with margin — the cure is always pre-turn speed management, not heroics after entry.

CONSPICUITY is the most important passive safety strategy for motorcyclists — the ability to be seen by other road users. Research consistently shows motorcyclists are frequently struck because drivers looked but 'didn't see' the motorcycle — a phenomenon caused by smaller frontal profile and the brain's tendency to filter out objects it doesn't expect. DAYTIME RUNNING LIGHTS significantly improve conspicuity — a lit headlight approaching is more likely to register in a driver's peripheral vision and trigger attention. This is why motorcycles manufactured after 1978 have headlights that come on automatically when the engine runs. In addition to headlights, conspicuity is improved by: bright/reflective gear; lane positioning in the center-left of the lane (most visible to oncoming traffic); avoiding vehicles' blind spots.

MAXIMUM BRAKING requires using both brakes: FRONT BRAKE: provides approximately 70% of total stopping power (weight shifts forward under braking, increasing front tyre traction); start with light pressure, increase progressively; too-rapid application can lock the front wheel causing a dangerous fall. REAR BRAKE: provides approximately 30% of total stopping power; can be applied more aggressively than the front; locking the rear causes a skid that's manageable (the bike stays upright and the skid can be controlled); COORDINATED APPLICATION: apply front first to initiate weight transfer; then apply rear smoothly; increase both progressively to maximum stopping force; with ABS, apply both fully and let the system modulate. The goal is maximum deceleration without wheel lockup — ABS enables more aggressive application by preventing lockup electronically.

ATGATT (All The Gear, All The Time) is the safety philosophy promoted by MSF, experienced riders, and safety researchers: wear full protective gear on EVERY ride — not just when going fast, long distances, or on highways. WHY IT MATTERS: statistics show the majority of motorcycle crashes occur within 5 miles of home and at lower speeds — most riders who crash 'weren't planning on crashing today' and many were on routine, familiar rides. Protective gear includes: HELMET (DOT approved minimum); JACKET (leather or textile with CE-rated armour at shoulders, elbows, and back); GLOVES (full finger, ideally with palm sliders); PANTS (armoured — abrasion resistance is critical; jeans offer little protection); BOOTS (ankle support above the ankle bone; this is what separates motorcycle boots from regular shoes). Road rash, ankle fractures, and head injuries account for most motorcycle crash injuries — each is addressed by a specific piece of ATGATT.
