Home › CDL Practice Tests › Combination Vehicles Questions › Question 214
Why should you be especially careful about adverse weather when pulling doubles or triples?
- A.Extra trailers swing and can be pushed by wind more easily, and slick roads multiply the chance of a trailer folding or rolling, so some carriers and drivers avoid doubles in severe conditions
- B.Doubles handle ice better than single trailers
- C.Weather does not affect multi-trailer combinations
- D.Triples are required to keep driving in storms to maintain schedules
Correct answer
A. Extra trailers swing and can be pushed by wind more easily, and slick roads multiply the chance of a trailer folding or rolling, so some carriers and drivers avoid doubles in severe conditions
Why
Each added trailer is another pendulum the wind and the road can work on. In high wind or on ice, the margin that makes doubles manageable in fair weather can disappear.
