What are some common mistakes people make when using wheel chocks?

Some common mistakes people make when using wheel chocks include improper sizing, incorrect positioning, and inadequate quantity. Firstly, using a chock that's too small for the tyre diameter can result in a vehicle rolling. It's crucial to choose the right size for maximum effectiveness. Secondly, positioning chocks on the wrong side of the tyre or on uneven surfaces can reduce their efficiency. Ensure chocks are placed snugly against the tyre's downslope, on level ground. Lastly, using too few chocks can compromise their ability to secure the vehicle. For optimal results, utilise chocks on both sides of the wheels in pairs, ideally on the same axle. Avoiding these common errors can significantly enhance wheel chock performance and safety.
