California DMV Motorcycle Knowledge Test (M1)Rules of the Road and Impaired RidingMedium

A motorcyclist is riding on a highway and notices a large piece of debris in their lane just ahead. What is the most effective technique for avoiding this hazard?

  1. AFlash high beams and hope the debris moves out of the way.
  2. BBrake hard and swerve simultaneously.
  3. CUse a quick swerve (countersteering) without braking if there is enough space and time.
  4. DMaintain speed and try to ride over the debris if it looks small.
Show answer & explanation

Correct answer: C. Use a quick swerve (countersteering) without braking if there is enough space and time.

For sudden hazards that require immediate avoidance, a quick swerve using countersteering is often the most effective technique, provided there is enough space and time. Braking and swerving simultaneously can lead to a loss of control.

Why the other options are wrong

  • A. Flashing high beams is ineffective against stationary debris and does not help in avoiding it.
  • B. Braking hard and swerving simultaneously can cause the tires to lose traction, leading to a skid or fall.
  • D. Riding over debris, even if it looks small, can cause a loss of control or damage to the motorcycle.

Quick Swerve (Countersteering)

A technique used to rapidly change a motorcycle's direction by pushing the handlebar opposite to the desired turn, then leaning.

  • Most effective for sudden hazard avoidance.
  • Should be done without braking if possible.
  • Requires practice to master.
  • Push right to go right, push left to go left.

Memory trick: Push to turn, not to fall!
