California DMV Motorcycle Knowledge Test (M1)Motorcycle Controls and Basic ManeuversHard
During a high-speed emergency stop, a rider feels the rear wheel begin to lock and skid. What is the most appropriate immediate action to regain control?
- AIncrease front brake pressure while maintaining the locked rear brake.
- BRelease both front and rear brakes completely.
- CSlightly release the rear brake pressure to allow the wheel to roll, while maintaining front brake.
- DPull in the clutch and let the motorcycle coast to a stop.
Show answer & explanationAnswer & explanation
Correct answer: C. Slightly release the rear brake pressure to allow the wheel to roll, while maintaining front brake.
If the rear wheel locks, slightly releasing the rear brake pressure can allow the wheel to regain traction. It's crucial to maintain front brake pressure as the front brake provides most of the stopping power.
Why the other options are wrong
- A. Increasing front brake pressure while the rear is locked can cause a high-side crash if the rear regains traction suddenly, or cause the front to lock up.
- B. Releasing both brakes will significantly increase stopping distance and may not prevent a fall if the bike is already unstable.
- D. Pulling the clutch removes engine braking and won't help regain control of a skidding rear wheel; it also increases stopping distance.
Rear Wheel Skid Recovery
The technique of regaining control of a motorcycle when the rear wheel has locked and begun to skid, typically involving a controlled release of rear brake pressure.
- Requires quick, precise action.
- Maintain front brake pressure.
- Avoid sudden movements.
Memory trick: Rear lock, ease back, front attack, get on track.
