Home › CDL Practice Tests › Combination Vehicles Questions › Question 226
How should your following distance change when pulling doubles or triples compared with a single trailer?
- A.Increase it further, because the longer, multi-unit combination needs more distance to stop and gives you less ability to maneuver in an emergency
- B.Decrease it, because extra trailers add braking axles
- C.Keep the car rule of two seconds
- D.Following distance depends only on weather, not on the vehicle
Correct answer
A. Increase it further, because the longer, multi-unit combination needs more distance to stop and gives you less ability to maneuver in an emergency
Why
More length and more articulation mean fewer emergency options, so distance ahead is your main protection. The one-second-per-10-feet rule, plus additions for speed and conditions, grows with the outfit.
