California DMV Motorcycle Knowledge Test (M1)Lane Position and VisibilityMedium
You are riding on a multi-lane highway, and a car in the lane to your left is beginning to merge into your lane without signaling. What is the most important immediate action you should take to manage this space and avoid a collision?
- AHonk your horn and maintain your speed to assert your lane position.
- BAccelerate quickly to get ahead of the merging vehicle before it enters your lane.
- CImmediately swerve to the right shoulder to avoid the merging vehicle.
- DSlow down to create a space cushion ahead of you, and if necessary, move to the right portion of your lane.
Show answer & explanationAnswer & explanation
Correct answer: D. Slow down to create a space cushion ahead of you, and if necessary, move to the right portion of your lane.
The most important immediate action is to slow down, creating space ahead of you. This provides a buffer and time to react. Moving to the right portion of your lane (if safe) further increases your lateral separation from the merging vehicle and may offer an escape path.
Why the other options are wrong
- A. Honking might alert the driver, but maintaining speed risks a collision if they continue to merge.
- B. Accelerating could put you directly in the path of the merging vehicle, especially if they speed up too.
- C. Immediately swerving to the shoulder is an uncontrolled maneuver that could lead to loss of control or collision with other hazards.
Unsignaled Merge Response
When a vehicle merges into your lane without signaling, immediately slow down to create space, and if safe, move to the right of your lane to increase separation.
- Prioritize creating a space cushion.
- Increase lateral separation if possible.
- Be prepared for evasive action.
