You see a lorry involved in a collision on a dual carriageway. It has orange hazard warning plates and other dangerous goods signs on it. What should you do?

Explanation

The Highway Code Rule 285 says that if an incident involves a vehicle containing dangerous goods, you must follow the guidance in Rule 283 and treat it with extra caution. You should stay well back, avoid smoking or using naked flames, and call the emergency services, clearly stating that the vehicle is carrying dangerous goods. You must not approach the vehicle or attempt to move any containers yourself.
