If you need to slow down while driving on a slippery road, the first thing you should do is:

  1. Firmly apply your brakes.
  2. Take your foot off the gas pedal. ✓
  3. Apply your parking brake.
  4. Pump your brakes.

Answer: B. Take your foot off the gas pedal.

Take your foot off the gas pedal first when you need to slow down on a slippery road.

Why this is the answer

The handbook's winter-driving and skid guidance says to lift off the gas and let the vehicle slow as traction returns. It also warns that heavy braking with regular brakes can make the situation worse. So the first move is to ease off the accelerator, then brake carefully and gently if you need more slowing. That is why taking your foot off the gas pedal fits the manual better than braking firmly right away.

Why the other answers are wrong

Remember it

Let up on the gas before you touch the brake when traction is low.
