Abstract:
A vehicle-collision prevention system wherein a first vehicle has four sides, including front and rear sides, with one or more of its sides provided with solenoid-operated air valves with inlet and outlet ports, compressed air tanks and a manually-operated switch, a circuit also including a voltage supply, each of said air valves being connected to a compressed air tank with piping, with all solenoids being connected in parallel with the same, single voltage supply, and in series with said switch, preferably having said air valves mounted on said front side; when said switch being closed, all air valves are opened to blast high pressure air out of said front side of said vehicle to provide a cushion behind another second vehicle traveling along the road ahead, with which said first vehicle may collide; a sufficient number and size of air valves with sufficient air pressure being provided to offer the needed air cushion to avoid a hard collision; the air blasts from said valves both causing said-first vehicle to slow down and pushing said second vehicle ahead and out of the way.
