How to Use Wheel Chocks: The Basics, Proper Placement, and Regulations
How to Use Wheel Chocks: The Basics
Make sure you invest in chocks specifically designed for the type of vehicle you are driving. You should consider wheel size, vehicle weight, and the surface you'll be chocking on. Larger, heavier vehicles will require larger chocks, and vice versa. You may need specific chocks if you'll be chocking in muddy or icy conditions, or on significantly unlevel surfaces.
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 chocks manufactured and regulated to do the job right. Keep sets of chocks in the truck or trailer; you cannot rely on the docks to always have them. That being said, it is best practice for the docks to have wheel chocks, and for that matter, chocks that are chained to the dock to prevent theft or loss.
Wheel Chock Placement at a Loading Dock
Upon arrival, set the brakes and activate the locking mechanism included on the dock. You’ll need to park as firmly and as closely to the dock as possible. Engage the chocks on both the left and right wheels that are closest to the loading dock. Be extremely mindful when you know a forklift will be driving in and out of the trailer from the edge of the dock. When the wheels are not chocked, the trailer can become dislodged, creating a space between the dock and the trailer. Forklift operators can get caught in that space or fall into the gap that is created. Do not drive a forklift into a trailer until you are sure the wheels are properly and safely chocked.
Wheel Chock Placement on a Free-Standing Trailer
Chock both the left and right rear axle wheels. It is best practice to chock both the front and back wheels on both sides of the vehicle. Sometimes it’s even better to chock the front and back of each tire.
OSHA Wheel Chock Requirements
Federal requirements on wheel chocking can be confusing, but one thing is clear - you SHOULD chock your wheels when loading and unloading. Federal regulation OSHA 29 CFR 1910.178(k)(1) says "the brakes of highway trucks shall be set and wheel chocks placed under the rear wheels to prevent the truck from rolling while they are boarded with powered industrial trucks."
