Your combination vehicle is 60 feet long and you are traveling at 50 mph. What following distance should you allow?
- A.5 seconds
- B.6 seconds
- C.7 seconds
- D.10 seconds
Correct answer
C. 7 seconds
Why
Above 40 mph you start with one second per 10 feet of length, which gives 6 seconds for a 60-foot vehicle, then add one more second for the higher speed. That makes 7 seconds the correct gap.
