Driver's License Test Prep
California Practice Defensive Driving

A vehicle merges in front of you too closely. What should you do?

  1. A.
    Take your foot off the accelerator to open space Correct
  2. B.
    Brake firmly to fall well behind them
  3. C.
    Move over immediately to another lane
The Why

The answer is "Take your foot off the accelerator to open space"

The manual says to take your foot off the accelerator when a vehicle merges too close in front of you, which opens space without startling the driver behind. Choice B comes from drivers who reach for the brake pedal on instinct, but a firm brake here creates a rear-end risk the coast-off-the-throttle avoids.

Why the others miss

The traps in the wrong answers

B. Brake firmly to fall well behind them

The manual does not tell you to brake in this situation; braking firmly startles the driver behind you. This answer reaches for the brake pedal on instinct, when the manual's move is a coast-off-the-throttle without touching the brakes.

C. Move over immediately to another lane

The manual's step here is a speed change, not a lane change. This answer applies the general 'move out of trouble' habit instead of the specific throttle-lift the manual prescribes.
