NOVELTY - A multi-purpose vehicle contains a special washing liquid comprising a specific solution that is capable to take apart the molecular chains of hydrocarbons and/or other types of organic or inorganic compounds, through respective chemical, physical, and/or bacteriological processes.    USE - Multi-purpose vehicle such as emergency vehicle for re-establishment of safe and practicable road conditions, through cleaning and extraordinary maintenance of road platform and related parts involved in car accidents.    DETAILED DESCRIPTION - A multi-purpose vehicle (100) comprises:    (A) a mechanism for storage (101) of a special washing liquid (103);    (B) a mechanism for delivering the special washing liquid on the road platform, through a high-pressure jet (102);    (C) a mechanism for a fast suction (104), from the above road platform, of a resulting liquid (106) that is a mixture of the special washing liquid and other liquids or polluting materials (105), eventually lost by vehicles involved in the car accidents; and    (D) a mechanism for storage (107) of the above the resulting liquid (106) to submit it, as a special waste, to a special following treatment.    The special washing liquid comprises a specific solution that is capable to take apart the molecular chains of hydrocarbons and/or other types of organic or inorganic compounds, through respective chemical, physical, and/or bacteriological processes so that it realizes a special vehicle, supporting the intervention of operators (108, 109) directly on the site of accident, and these operators provide the re-establishment of normal road conditions, through cleaning and maintenance of road platform and related parts, and that means through aspiration and collection of liquids and other polluting materials eventually lost by vehicles involved in the same accident.
