At the scene of an accident you see an overturned lorry marked with a plain orange plate with no numbers on it. What does this mean and what precautions should you take?

An orange plate on a vehicle means it is carrying dangerous goods. Even with no specific numbers, the plate warns of a general hazard. Approach such a vehicle carefully, keep your distance and avoid any open flame.
KET reference: KET 212, appendix 4, 13: vehicles carrying dangerous goods are marked according to the ADR agreement (with orange plates).
