To prevent aggression, if you are driving below the speed limit and a line of cars has formed behind you, you should

  1. pull over and stop to let traffic pass ✓
  2. maintain your speed
  3. move to the right and drive on the shoulder
  4. slow down and signal the traffic to pass

Answer: A. pull over and stop to let traffic pass

You should pull over and stop to let the line of cars pass.

Why this is the answer

The handbook's list of ways to prevent other drivers from becoming frustrated includes pulling over to let other drivers go by when there is a line of vehicles behind you. It also says you can pull over to the side and let a tailgater pass. So when a line has formed behind you, the matching choice is to pull over and stop so they can pass. The handbook does not advise keeping your speed or driving on the shoulder.

Why the other answers are wrong

Remember it

A line of cars behind you is your cue to pull over and let them go.
