True or False: You should use the trailer brakes to stop a skid.

True False Only at high speeds Only for light trailers

Correct Answer:

False

Explanation:

Using the trailer brakes to stop a skid is not advisable, as they can exacerbate the situation rather than help stabilize the vehicle. In the case of a skid, the main concern is to regain control of the vehicle, which is best achieved by allowing the drive wheels to maintain traction. Engaging the trailer brakes could cause the trailer to swing out or jackknife, leading to a loss of control. In general, the correct response highlights the crucial understanding that when skidding occurs, the driver should focus on steering into the skid and carefully modulating the use of vehicle brakes, particularly the drive and steering brakes, to regain control. Maintaining the proper use of brakes is essential to ensure a safe recovery from a skid situation.
