When attaching a trailer to their vehicle, what must a driver check?
- Correct answerThat the load is evenly spread.
- That the load is positioned to the rear of the trailer.
- That the trailer has a spare wheel.
- That the load is positioned to the front of the trailer.
Explanation
Proper weight distribution helps to ensure the stability of both the towing vehicle and the trailer. In the trailer, the bulk of the load should be over the axles. If a heavy load is positioned at the front of the trailer, this will result in too much nose weight on the hitch of the towing vehicle and make it difficult to steer. If a heavy load is positioned at the rear of the trailer, this will result in reduced weight on the rear axle of the towing vehicle, which will make it more unstable.

在将拖车连接到车辆时，驾驶员必须检查什么？
- 负载均匀分布。
- 货物被放置在拖车的后部。
- 拖车有一个备用轮胎。
- 货物被放置在拖车的前部。
正确的重量分配有助于确保牵引车和拖车的稳定性。在拖车中，大部分载荷应位于车轴上方。如果重物放在拖车前部，会导致牵引车挂钩上的鼻重过大，难以转向。如果重物放在拖车后部，会导致牵引车后轴上的重量减少，从而使其更加不稳定。
