- A Two seconds
- B One car length for every 10 mph

How much following distance does the guide recommend when driving on snow or ice?
- A About eight to ten seconds
- B About three seconds
- C About four to five seconds
- D About 15 to 20 seconds
Show answer
A. About eight to ten seconds
Stopping takes much longer on snow or ice, so leave about eight to ten seconds between you and the vehicle ahead. Brake gently and smoothly to avoid skidding.

A driver is tailgating you on a two-lane road with no right lane to move into. What should you do?
- A Brake suddenly a few times to warn them that they are too close
- B Wait until the road ahead is clear, then slow down gradually
- C Speed up to get away from them
- D Stop in your lane to make them go around
Show answer
B. Wait until the road ahead is clear, then slow down gradually
If you are tailgated and cannot move right, wait for a clear stretch and slow down slowly so the driver can pass. Never slow down suddenly to discourage a tailgater.

Your total stopping distance is made up of which two parts?
- A Braking distance plus following distance
- B Reaction distance plus following distance
- C Braking distance plus skid distance
- D Reaction distance plus braking distance
Show answer
D. Reaction distance plus braking distance
Stopping distance is your reaction distance, the distance covered before you hit the brakes, plus braking distance. Speed, fatigue and bad brakes all make it longer.
