Abstract: A motor vehicle including a passenger compartment is rendered collision resistant by a wedge member formed at the front of the vehicle defined by a forward most apex designed to run close to the ground, a rigid pan extending horizontally backwardly from the apex underneath the vehicle and an inclined ramp which extends upwardly and rearwardly from the apex to a position over the passenger compartment. The suspension of the vehicle is arranged so that on engaging an oncoming vehicle or the like the apex is forced downwardly to engage the pan with the ground so that the ramp acts to allow the oncoming vehicle to run up and over the vehicle while the vehicle continues to slide forwardly on skids or rollers on the underside of the pan.
