Which driver actions can cause a commercial vehicle to skid?
Correct answer: D – All of the above
A skid occurs when the tires lose traction. The CDL manual identifies over-braking, over-steering, over-acceleration, and driving too fast for conditions as causes. Controlling speed and making smooth steering, braking, and acceleration inputs help preserve traction and reduce the likelihood of a skid.
