A vehicle ground collision prevention method involves acquiring a geometric profile of a road feature, the geometric profile defining a shape of the upper surface of the road feature, acquiring wheel diameters and inter-axle distances for a vehicle, generating an interference boundary based on the road feature geometric profile, wheel diameters and inter-axle distances, where the interference boundary is an upper envelope bounding the trajectories of all points on the road feature geometric profile as observed in a vehicle-fixed reference frame as the vehicle passes over the road feature, acquiring an underbody profile of the vehicle, the underbody profile defining the shape of the lower surface of the vehicle, calculating a ground clearance curve for the vehicle-road feature pair by comparing the underbody profile with the interference curve, determining a minimum ground clearance over the ground clearance curve, and providing information regarding the minimum ground clearance to the vehicle's driver.
