Correct answer

Reduce speed significantly before the ramp begins, more than for a single trailer, because of rearward amplification and rollover risk

  1. A Reduce speed significantly before the ramp begins, more than for a single trailer, because of rearward amplification and rollover risk
  2. B Brake only on the curve itself
  3. C Accelerate to use the ramp's grade
  4. D Maintain highway speed

Why this is the answer

Highway off-ramps are a common rollover site for doubles and triples. The combination of rearward amplification (small steering inputs at the tractor become large lateral motions at the rear trailer), high center of gravity, and a curve that may seem mild for a passenger car can roll the rear trailer if entered too fast. Reduce speed substantially before the ramp begins — earlier than you would in a single-trailer combination — and maintain steady moderate speed through the curve. Brake on the straight approach, not in the curve. Posted advisory speeds on ramps are for cars; doubles and triples typically should be 10-15 mph below the advisory.

About this topic: Pulling Doubles and Triples

Pulling doubles and triples means managing the most unstable combination on the road: the rear trailer whips, rolls and jackknifes more easily, following distance must grow, and the sequence of air-line and brake checks is longer. These questions cover the handling rules specific to multiple trailers. This is one of 29 Doubles and Triples questions on pulling doubles and triples, each with a full explanation on a single study page.
