Home › CDL Practice Tests › Combination Vehicles Questions › Question 220
Why does a combination vehicle need extra space when joining traffic or changing lanes, beyond what a car needs?
- A.Combination vehicles are allowed to merge without gaps
- B.It accelerates slowly, is very long, and needs a much larger gap so its full length can merge without forcing others to brake
- C.Length does not affect merging, only speed does
- D.Other drivers are required to make room by law in all cases
Correct answer
B. It accelerates slowly, is very long, and needs a much larger gap so its full length can merge without forcing others to brake
Why
A gap that fits a car will strand a combination half-merged across lanes. Judging a gap by the whole length of the outfit, plus its slow acceleration, is a core space-management skill.
