When pulling a set of doubles with trailers of different weights, where should the more heavily loaded semitrailer be positioned for the safest handling on the road?

In the rear position, behind the lighter trailer, so the tractor pulls the lighter load first

Position doesn't matter as long as total combination weight stays under the legal limit

The heaviest trailer should alternate position periodically during a trip to balance tire wear

Correct!

Correct. The manual states directly that for the safest handling on the road, the more heavily loaded semitrailer should be in the first position behind the tractor, with the lighter trailer in the rear.

✗

Not quite.

Wrong. This is the reverse of the documented rule. Putting the heavier trailer in the rear position is specifically what the placement rule warns against for safe handling.

The correct answer is A: In the first position, directly behind the tractor, with the lighter trailer in the rear.

✗

Not quite.

Wrong. Legal weight limits are a separate requirement from handling safety. A combination can be fully within legal weight limits and still be dangerously arranged if the heavier trailer is placed in the rear.

The correct answer is A: In the first position, directly behind the tractor, with the lighter trailer in the rear.

✗

Not quite.

Wrong. There is no rule or practice of alternating trailer position mid-trip for tire wear. Placement is determined once, based on load weight, for handling stability, not rotated for wear reasons.

The correct answer is A: In the first position, directly behind the tractor, with the lighter trailer in the rear.
