Final answer:
The best way to tell if your trailer has started to skid is to look for signs such as sideways movement or loss of control.
Step-by-step explanation:
The best way to tell if your trailer has started to skid is to look for signs such as sideways movement or loss of control. Skidding can occur when the tires lose traction with the road surface. This can happen if you are going too fast, braking too hard, or taking a turn too sharply.
One way to prevent skidding is to make sure your trailer is properly loaded. If your trailer is heavily loaded, it will exert more pressure on the tires, improving their grip on the road. However, if your trailer is nearly empty, it will be more prone to skidding as there is less weight to provide traction.
Another way to prevent skidding is to drive at an appropriate speed for the road conditions. Slow down when driving in wet or icy conditions, and avoid sudden braking or acceleration. This will help maintain traction and reduce the risk of skidding.
