Doubles and Triples Practice Test


Question #1 of 18

How do you check to make sure the trailer height is correct before coupling?


Trailer height never changes!

The height is always the same.

Visually check to make sure that the rear trailer is slightly lower than the center of the fifth wheel, so trailer is raised slightly when dolly is pushed under it.

Visually check to make sure that the lead trailer is slightly higher than the center of the fifth wheel, so trailer is raised slightly when dolly is pushed under it.

None of the above
