Commercial Driver's License

Answer: C - When pulling doubles or triples, drivers must be aware of the added danger of the last trailer rolling over. While it is true that pulling doubles or triples always comes with the added risk of a rollover, the last trailer in line is often the one that will roll first. To prevent a rollover, steer gently and slow down on curves and turns. Understand that the posted speed limit may be too fast for vehicles pulling doubles and triples. Slow down!
