CDL Doubles/Triples Endorsement Practice Exam

Experiencing trailer sway can be a challenging situation, particularly when driving double or triple trailers, which have a higher center of gravity and are more susceptible to swaying. The correct approach to handling trailer sway is to slow down gently and steer straight. When you gently reduce your speed, you decrease the aerodynamic forces acting on the trailers, which can help to stabilize them. Stepping on the brakes abruptly can lead to further loss of control and exacerbate the sway. By steering straight, you maintain a steady course, which helps to realign the trailers and reduce the likelihood of a jackknife situation. In contrast, accelerating can worsen the sway, as increased speed heightens the instability of the load. Aggressive steering can also lead to overcorrection, causing further instability. Changing lanes abruptly may introduce additional risks, such as colliding with other vehicles or losing control of the trailers. Thus, slowing down gently and steering straight is essential for regaining control and maintaining safety while navigating a situation of trailer sway.
