ALWAYS chock wheels at the center point of the wheel. NEVER chock wheel at off-center or at an angle.
Improper chocking can lead to the chock not working correctly and/or could lead to possible injury.
ALWAYS position wheel chock against the wheel so that it is making contact.
If chocking on an incline or decline, chock the wheels accordingly based on type of vehicle, weight, tire diameter/size etc. Consult full “Wheel Chock Guidelines” for more information.
ALWAYS consider the surface/terrain and environment around the vehicle. Soft “Soil”, wet, or slippery terrain can affect the usability of wheel chocks and/or cause a potential for failure.
TIRE SIZES/GVW - Always consider the tire size and type of tire/wheel configuration. Radial vs. Biased Tires may require a different sized chock. Always consider the vehicles “Gross Vehicle Weight”. Chocks are designed based on tire diameter and GVW.
ALWAYS use a minimum of (2) wheel chocks.
Top of Chock — Grips for non-slip of the tire
Bottom of Chock — “V” shaped for better leveling on uneven surfaces like concrete
