Make sure your vehicle is off, parking break engaged and in the park position.
ALWAYS chock wheels at the center point of the wheel. NEVER chock wheel at off-center or at an angle.
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.
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.
Always consider the vehicles “Gross Vehicle Weight” (for “hauler” type vehicles, always)
