Putting the wrong fuel into a truck or heavy goods vehicle (HGV)/PSV presents significant risks, including the potential for severe engine damage and widespread road disruptions. Should a vehicle be operated with the incorrect fuel, it not only worsens the initial problem but also adds complexity to the situation, compounding damage and posing additional hurdles for drivers and emergency services alike. Furthermore, the consequences of misfueling extend beyond the vehicle itself, as it can block entire sections of petrol station fuel pumps, inconveniencing other motorists and potentially impeding critical emergency operations.
