California DMV Motorcycle Knowledge Test (M1)Motorcycle Controls and Basic ManeuversHard
A rider encounters a sudden, unexpected obstacle in their lane at highway speed. To avoid a collision, which of the following actions should be prioritized?
- ASwerving around the obstacle while maintaining or slightly increasing throttle.
- BApplying both brakes as hard as possible while maintaining a straight line.
- CDownshifting rapidly to use engine braking.
- DAttempting to steer around the obstacle without braking.
Show answer & explanationAnswer & explanation
Correct answer: A. Swerving around the obstacle while maintaining or slightly increasing throttle.
At highway speeds, swerving (emergency lane change) is often the fastest way to avoid an obstacle. Maintaining or slightly increasing throttle during a swerve helps stabilize the motorcycle and maintain ground clearance, which is crucial for control.
Why the other options are wrong
- B. Hard braking at highway speeds, especially in an emergency, can lead to skidding and loss of control, and may not avoid the obstacle in time.
- C. Downshifting is too slow for an immediate emergency maneuver and can upset the bike's balance if done abruptly.
- D. Steering around without braking or swerving is too slow and may not provide enough evasive action.
Emergency Swerving
A rapid, controlled change of direction to avoid an immediate hazard, often involving countersteering and maintaining throttle.
- Prioritized at higher speeds.
- Involves quick countersteering.
- Requires maintaining or slight throttle increase.
Memory trick: Look, Press, Roll – Swerve to live.
