Home › CDL Practice Tests › Combination Vehicles Questions › Question 228
Why do some states and carriers restrict where and when triples may operate?
- A.Triples are restricted because they are too slow for any highway
- B.Triples are very long and demanding to handle, so they are limited to certain highways and conditions where their length and swing can be accommodated safely
- C.Restrictions exist only for fuel tax reasons
- D.Triples are banned everywhere in the United States
Correct answer
B. Triples are very long and demanding to handle, so they are limited to certain highways and conditions where their length and swing can be accommodated safely
Why
A triple needs enormous gaps, wide turns, and forgiving roads, which not every route offers. Limiting them to suitable highways is a recognition of their handling reality, not just bureaucracy.
