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. ## Claims ### Claim 1 A multi-purpose module (450), configured to be installable 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 comprising: 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) have been eventually lost by vehicles as a consequence of car accidents or breakdown; a suction system (431) suitable to remove, from the road platform, the above resulting emulsion (430), obtained from polluting materials mixed to the washing/treatment solution (428); the suction system further including a suction tube (407) for removing solid and not biodegradable debris from the car accident; the vehicle further including: an internal combustion engine (419) which, through a double oil-dynamic pump and a three-way distributor (425), pushes the pressurized oil contained in a hydraulic circuit, allowing its motion in direction of two hydraulic motors (404, 409), that are required to operate both said high-pressure water gun (408) and said suction system (431); a level sensor configured to measure the quantity of liquid in said suction tank (405) such that, when contents in the suction tank reach a particular level, said level sensor is configured to switch off said combustion engine (419). ### Claim 2 (depends on 1) The multi-purpose module of claim 1 further comprising: a GPS system (Global Positioning System), or a satellite system for detecting the geographical position, having an electronic circuit activated by the ON position switched on the control panel of the module (450); said GPS system further comprises communication means using a SIM card to allow the transmission of data, through a network of mobile and/or wireless communication, to an Headquarter, such data relating to geographical coordinates of the vehicle and time of its arrival on the place of accident. ### Claim 3 (depends on 1) The multi-purpose module of claim 1 further comprising: an oil tank (418) belonging to said hydraulic circuit, positioned at the center between said tank (415) containing clean water and said tank (414) containing water mixed to a specific washing liquid and a specific treatment liquid, thus obtaining a tripartite parallelepiped tank, such as to determine a heat exchange through both the walls of contact and the walls of some serpentine tubes in which the oil flows; these serpentine tubes work as “radiators” because they are placed inside tank (415), containing clean water, and tank (414), containing water mixed to a specific washing liquid and a specific treatment liquid. ### Claim 4 (depends on 1) The multi-purpose module of claim 1 including: two source points of oil, connected respectively to said hydraulic motor (409) of the washing circuit (423) and to said hydraulic motor (404) of the suction circuit (424); wherein each of said hydraulic motors (404, 409) is connected by its own source point, and only two branches are connected to the main circuit: one connected to the high-pressure water gun (408), necessary for washing, and another connected to the aspirator (407), necessary to remove polluting liquids (429) and debris. ### Claim 5 (depends on 1) The multi-purpose module of claim 1 wherein the diameter of the suction tube has been reduced compared to that of the prior art, in such a way to increase the speed of the suction process and therefore to improve the suction power of the suction system. ### Claim 6 (depends on 1) The multi-purpose module of claim 1 wherein the diameter of the drain pipe connected to the suction tank (405) has been increased compared to that of the prior art, in such a way to facilitate and speed up the flow of such materials, when they are discharged to treatment and/or disposal plants. ### Claim 7 (depends on 1) The multi-purpose module of claim 1 including: a terminal for electrical connection to ground, that allows to discharge any leakage of electrical current; all the electrical devices belonging to the multi-purpose module are connected to a unique and to the same circuit connected to ground, in such a way to give to the entire system a better safety against possible accidents to operators and to assure a better protection against damage to the components of the same module (450).
