method and system for preventing vessels from surfaces, in particular of departures of freeways and expressways in an undesired direction

摘要

In a method and a system for preventing driving in the undesired direction onto road surfaces, in particular exits of motorways and fast roads, visibility-hindering agents, preferably a liquid, slurry or dispersion, in particular a dye dispersion, are applied, in particular sprayed or poured, from outside, in particular from the edge of the road, onto the windscreen. As a result, the driver of the vehicle travelling in the undesired direction is made to stop immediately and is prevented continuing in the undesired direction.
