Question

DentroTest · Accepted Answer

The General Traffic Regulations establish that any vehicle of more than 3,500 kg maximum authorized mass (MAM) immobilized on a noticeable slope must be properly chocked, in addition to having the parking brake applied and the appropriate gear engaged (first gear on uphill slopes and reverse on downhill slopes). If approved chocks are not available and there is a curb, the regulatory way to chock the vehicle is to rest one of the steered wheels against the curb. On uphill slopes, the steered wheels must be turned toward the center of the roadway, so that the rear part of the tire rests against the curb, preventing the truck from rolling backward. On downhill slopes, they would be turned outward (toward the curb). It is strictly prohibited to use natural or improvised items such as stones or pieces of wood as chocks.
