Home › CDL Practice Tests › Combination Vehicles Questions › Question 74
Why must you leave much more following distance with a combination vehicle?
- A.It stops more slowly, and hard emergency braking can cause sway, jackknife, or rollover
- B.Only because the law requires double distance
- C.Following distance does not change with size
- D.To save fuel only
Correct answer
A. It stops more slowly, and hard emergency braking can cause sway, jackknife, or rollover
Why
Extra space is what lets you brake gently and steer smoothly instead of making the violent inputs that destabilize a combination. Space buys the smoothness that keeps trailers upright.
