Abstract: A vehicle for re-establishing safe roadway conditions after a car accident by cleaning the roadway. The vehicle includes a first tank containing clean water; a second tank containing a washing liquid for washing oil and other fluids off the road; and a suction tank containing emulsion obtained by collecting the washing liquid and the oil materials. The vehicle also includes a high-pressure water gun; a suction system for removing the emulsion from the roadway; and a suction tube for removing debris from the road, such as broken glass and pieces of plastic. The high-pressure water gun and suction system are powered by an internal combustion engine which powers a pump and three-way distributor which pumps pressurized oil through a hydraulic circuit. There is also a level sensor to measure the quantity of liquid in the suction tank so that the combustion engine is switched off when suction tank is full.

Abstract: Multi-purpose module (450), preferably installed on a light commercial vehicle, for re-establishment of safe and practicable road conditions, after car accidents, through cleaning of the road platform, said vehicle being equipped by:—a tank (415) containing clean water; a tank (414) containing water mixed to a specific washing liquid—ecological surfactant—and a specific treatment liquid for the road platform—so called molecular chain destroyer, to be sprayed on oil and related oil products (428); a suction tank (405) containing emulsion (430) obtained by collection of the washing/treatment liquids and the polluting oil materials;—a high-pressure water gun (408), including a rain jet adjustment, providing a jet of the above said solution (428) on the road platform, where polluting functional liquids (429)—lubricating oils, fuels, cooling substances, etc.
