Driver and Vehicle Standards Agency officers have the power to stop vehicles on all roads, including motorways and trunk roads. 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’).
