Bricks would be safe enough as wheel chocks because the rubber tyre spreads the load. (Imagine trying to chock a railway wagon with a brick however, and it would be another matter.) But all the same, the proper wedge-shaped blocks are probably best.Aug 8, 2004
Are plastic wheel chocks safe?
Polyurethane plastic is the second most common material for wheel chock. They're better at resisting cuts, blunt damage, water damage, and wind damage than rubber chocks, and they're lighter-weight than rubber or aluminum. But, plastic wheel chocks are not as high-strength as aluminum or steel alloy chocks.Dec 31, 2019
Can I use a rock as a wheel chock?
Basic Chocking Never use a make-shift chock. That includes lumber, bricks, rocks or any other creative contraption you come up with on the fly. Use only proper wheel chocks that are manufactured and regulated to do the job right.Aug 26, 2015
