Show answer & explanationAnswer & explanation
Correct answer: C. Signal your intention to change lanes for at least five seconds.
After checking mirrors and blind spots, signaling your intention is the next critical step. California law requires signaling for at least five seconds before changing lanes on a freeway to give other drivers ample warning.
Why the other options are wrong
- A. Tapping brakes is usually for slowing down or warning of a hazard, not for initiating a lane change.
- B. Accelerating without signaling first can be dangerous and unpredictable for other drivers.
- D. While a final check is good, signaling must precede the actual maneuver after initial checks.
