If you are being passed by a large truck, you should:

  1. Speed up.
  2. Slightly reduce your speed. ✓
  3. Crowd the truck.
  4. Make it more difficult for the truck to pass you.

Answer: B. Slightly reduce your speed.

When a large truck is passing you, slightly reduce your speed.

Why this is the answer

The Texas handbook says that when a truck passes you, you should help the truck driver by keeping to the far side of your lane and slightly reducing your speed. It also says not to speed up while the truck is passing. That makes the truck driver's pass easier, so the correct action is to lower your speed a little rather than speed up or crowd the truck.

Why the other answers are wrong

Remember it

When a big truck is coming around you, be a helper: ease off the gas a little and give it room.
