The below diagrams demonstrate the correct placement of wheel chocks.
Parking On Neutral Ground
If parking on flat ground, or grade cannot be determined, place chocks on both sides of driver side tire.
Consider using four chocks if care for total safety is a concerned.
Parking On Grade
If parking on a grade, place chocks against the grade on both ends of one axle.
Chock against the heaviest weighted axle to allow qualified chocks to function at their greatest potential.
Parking On Grade (Dual Axle)
Consider using four sets of chocks on two axles if care for total safety is a concern, for heavily weighted axles.
Employing two pairs of chocks will deminish the load by half over standard paired usage.
