California DMV Motorcycle Knowledge Test (M1)Hazard Avoidance and Emergency ManeuversHard
You are riding your motorcycle when you realize your throttle is sticking, causing the engine to rev higher than desired. What is the immediate action you should take?
- AApply the brakes firmly while attempting to free the throttle.
- BShift into a higher gear to reduce engine RPM.
- CActivate the engine cut-off switch and pull in the clutch.
- DTwist the throttle back and forth forcefully to unstick it.
Show answer & explanationAnswer & explanation
Correct answer: C. Activate the engine cut-off switch and pull in the clutch.
A stuck throttle is a serious emergency. The quickest way to cut power to the rear wheel is to activate the engine cut-off switch AND pull in the clutch. The cut-off switch stops the engine, and the clutch disengages the engine from the transmission, ensuring no power reaches the wheel while you slow down.
Why the other options are wrong
- A. Applying brakes against a powerful, accelerating engine can lead to brake fade or loss of control.
- B. Shifting to a higher gear may reduce revs but won't cut power entirely, and the throttle is still stuck.
- D. Forcefully twisting the throttle can damage it further or make it stick more severely.
Stuck Throttle Procedure
The emergency steps a motorcyclist must take if the throttle becomes stuck in an open position.
- Engine cut-off switch
- Pull in clutch
- Brake to stop safely
Memory trick: Switch Off, Clutch In, Brake Safe.
