The car behind you begins to pass you. You should:

  1. Maintain your speed so traffic will flow smoothly
  2. Pull to the right and stop so he can pass
  3. Slow down slightly and stay in your lane ✓
  4. Blow your horn to allow him to pass

Answer: C. Slow down slightly and stay in your lane

Slow down slightly and stay in your lane when the car behind you starts to pass.

Why this is the answer

The manual's section on being passed says that when another vehicle passes you on the left, you should ease off the gas a little and keep your car centered in your lane. Once that vehicle is safely past and ahead of you, you go back to your normal speed. Slowing a bit shortens the time the passing driver spends alongside you, and holding your lane keeps your position predictable so they have room to complete the pass.

Why the other answers are wrong

Remember it

When someone passes you, do less, not more: lift off the gas a touch and stay put in the middle of your lane.
