Answer options

  1. APumping the pedal rapidly to build pressure
  2. BSlowing the vehicle with the parking brake
  3. CShifting up to a higher gear Correct

Why

Shifting up lets the vehicle pick up speed and makes it even harder to stop, so it is the move to avoid. The helpful steps are to pump the pedal quickly to rebuild pressure, downshift, and use the parking brake with care.

Tip When a question asks what to avoid, remember that moving to a higher gear lets the vehicle gain speed and makes stopping harder.
