Driver and Vehicle Standards Agency officers have powers to stop vehicles on all roads, including motorways and trunk roads, in England and Wales. They will attract your attention by flashing amber lights
- either from the front requesting you to follow them to a safe place to stop
- or from behind directing you to pull over to the side by pointing and/or using the left indicator.
It is an offence not to comply with their directions. You MUST obey any signals given (see ‘Signals by authorised persons’).

Traffic officers have powers to stop vehicles on most motorways and some ‘A’ class roads, in England only. If traffic officers in uniform want to stop your vehicle on safety grounds (e.g. an insecure load) they will, where possible, attract your attention by
- flashing amber lights, usually from behind
- directing you to pull over to the side by pointing and/or using the left indicator.
You MUST then pull over and stop as soon as it is safe to do so. Then switch off your engine. It is an offence not to comply with their directions (see ‘Signals by authorised persons’).

Flashing headlights. Only flash your headlights to let other road users know that you are there. Do not flash your headlights to convey any other message or intimidate other road users.
Never assume that flashing headlights is a signal inviting you to proceed. Use your own judgement and proceed carefully.

- while stationary on the road
- when driving in a built-up area between the hours of 11.30 pm and 7.00 am
