What is the recommended speed when making a right turn with a double trailer?

Answer: C — Reduce speed to avoid tipping or jackknifing

When making a right turn with a double trailer, reducing speed is essential to maintain control of the vehicle and prevent instability. Double trailers have a longer overall length and a greater center of gravity than a single trailer, making them more susceptible to tipping over or jackknifing if taken too quickly. By decreasing speed before the turn, the driver is able to better navigate the turn while allowing for proper tracking of the rear trailer behind the front unit. This controlled approach helps ensure that the trailers remain aligned and do not swing out into other lanes or obstacles, which could occur at higher speeds. Maintaining a slower speed allows for a safer and smoother turn, thus significantly reducing the risk of accidents and improving overall maneuverability.
