CDL · Following distance

When the road is dry and visibility is good, how much time should separate a 40-foot bus traveling at 50 mph from the vehicle ahead of it?

Correct answer: 5 seconds.

Answer options

  1. A7 seconds
  2. B5 seconds Correct
  3. C4 seconds

Why

The guideline is one second for each 10 feet of vehicle length, so a 40-foot bus needs 4 seconds. Above 40 mph you add one more second, which brings the total to 5.
