If a trailer starts to skid, what is the recommended action?

Answer: B — Release the brakes to regain traction

When a trailer starts to skid, the recommended action is to release the brakes to regain traction. This approach helps to prevent further loss of control. When brakes are applied during a skid, particularly on a trailer, it can cause the wheels to lock, which will exacerbate the skidding motion rather than help to regain control. By releasing the brakes, you allow the wheels to start turning again, which can help restore traction and stability to the vehicle. This is crucial in a situation where skidding can occur due to slippery conditions or abrupt maneuvers. When traction is regained, it becomes easier to steer and control the vehicle effectively. Other potential actions, such as turning the wheel sharply or applying the emergency brake, can lead to worsened skidding or loss of control. Similarly, accelerating during a skid can also result in increased instability and further loss of control, making the situation more dangerous.
