CDL · Following distance
Your double-trailer rig is 100 feet long, and you are traveling 50 mph on a dry road with clear visibility. How many seconds of following distance should you leave at a minimum?
Correct answer: 11 seconds.
Answer options
- A11 seconds Correct
- B10 seconds
- C8 seconds
Why
Below 40 mph you need one second for each 10 feet of length, so a 100-foot rig needs 10 seconds. Above 40 mph you add one more second, for a total of 11.
