Your drive wheels have locked under braking and the vehicle is sliding. What sequence of actions regains control?

Correct answer: Get off the brake, turn quickly toward your intended path, then countersteer.

Answer options

  1. APush the brake harder, turn quickly toward your intended path, then countersteer
  2. BBrake even harder to stop the slide
  3. CGet off the brake, turn quickly toward your intended path, then countersteer Correct

Why

Releasing the brake lets the locked drive wheels start turning and grip again. A quick turn toward your intended path, followed by a countersteer as the vehicle straightens, keeps it from swinging into a slide in the opposite direction; more brake pressure just keeps the wheels locked.
