Abstract
A metal detector and distance sensor for a motor vehicle. A departure of the motor vehicle from a correct path indicated by one or two metal lines covered with paint in the road is signaled. The metals lines are formed by projecting a jet of metal in the gaseous state at high speed onto the road surface. A covering of paint is then formed over the metal line on the road surface. A turbine supplied by an air compressor projects the jet of metal in the gaseous state from a vehicle or a trailer having a metal supply device and a painting device thereon. A display indicates the direction of departure from the correct path and the distance separating the motor vehicle from a preceding vehicle. Alarm signals can be emitted upon the departure.
