The LPG is stored in the vehicle in liquid form and contained in a substantial LPG tank. An automatic, safety valve prevents overfilling of the tank. A number of other safety features are built into the tanks including a pressure release valve and a solenoid valve to shut off the flow when the engine stops. Crash tests have shown that gas-powered vehicles are extremely safe, as LPG is more difficult to ignite than any other fuels. Due to these properties and safety features, gas-powered vehicles are safer than petrol-powered vehicles.← Is it Safe?
