California · State-Specific Laws
Before changing lanes on a California freeway, the handbook specifically requires what additional check beyond your mirrors?
- Honking to warn other drivers
- A head check over the shoulder to clear your blind spot
- Flashing your high beams
- Tapping the brakes
Correct answer
A head check over the shoulder to clear your blind spot
Why this is correct
California's handbook requires a head-check over the shoulder in addition to mirror checks before changing lanes. Mirrors leave a blind spot that can hide a motorcycle or small car entirely. Signal at least 5 seconds before a freeway lane change so others can respond.
