A vehicle guidance and parking system that continuously guides the operator of a vehicle to a pre-determined parking position by using two laser beams impinging on a forward or rearward surface. The two lasers beams project to a substantially vertical surface to which a vertical line has been applied and the vehicle is guided by the operator such that the two laser beams are kept equidistantly horizontally centered around the line during the vehicle approach to maintain the correct lateral position in the pre-determined parking position. When the two laser beams converge on the vertical line, the vehicle is longitudinally positioned to the pre-determined parking position. Temperature compensation, due to the wide temperature of potential use range, is provided by the laser emitting device used in the vehicle guidance and parking system. A light blocking shroud is used around the vertical line in bright sunlight conditions when necessary to improve the visibility of the two laser beam outputs for vehicle maneuvering.
