What to do if…
an unmarked vehicle signals for you to pull over and you are unsure it is legitimate

Short answer

Put your hazard lights on to show you’ve seen them, drive calmly to the nearest well-lit public place, and (only if you can do so safely hands-free or via a passenger) call 999 to verify it’s the police.

Do not do these things

  • Don’t speed up, weave, or try to “lose” the vehicle (that can look like you’re trying to escape).
  • Don’t stop immediately in an isolated lay-by, dark side road, or anywhere you feel trapped if you can safely continue to a public, well-lit place.
  • Don’t use a hand-held phone while driving.
  • Don’t drive home (it reveals where you live).
  • Don’t unlock doors or get out of the car just because someone says “police” through the window.
  • Don’t hand over money, bank details, or your phone to “pay a fine” or “confirm identity”.

What to do now

  1. Acknowledge the signal without escalating. Indicate left and/or put your hazard lights on so it’s clear you’ve seen them and intend to stop.
  2. Slow down and choose a safer place to stop. Keep to the speed limit and head to the nearest busy, well-lit public place (petrol station forecourt, supermarket car park, or similar). Avoid secluded spots.
  3. Verify via 999 (safely). If you can do so safely hands-free (or a passenger can call), dial 999 and say:
    • your location and direction of travel
    • your vehicle make/colour and registration
    • that an unmarked vehicle is signalling you to stop and you’re driving to a well-lit public place If you cannot safely call while moving, drive to the public place first, then call from a stopped position.
  4. Stop there, stay in the car, and lock the doors. Keep the window mostly up at first. If it’s dark, you can switch on the interior light so your hands are visible.
  5. Ask for ID before you fully engage. Ask to see the officer’s warrant card (ID) and take a moment to look at the photo and name.
  6. If you’re still unsure, keep verification going. Ask for the officer’s name/collar number and which station/unit they’re attached to, and confirm via 999 (or stay on the line if you already called). Follow the call handler’s instructions.
  7. If anything feels wrong, prioritise staying safe. Tell 999 you do not feel safe and follow their guidance (for example, remaining in a public place, or proceeding to another agreed safe location).

What can wait

  • You do not need to decide right now whether the stop was “lawful” or whether to complain later.
  • You do not need to give a detailed explanation beyond what’s necessary to deal with the stop safely.
  • You do not need to check dashcam footage, message people, or post online while this is unfolding.

Important reassurance

Being cautious about an unmarked vehicle is a normal safety response. Verifying through 999 and stopping somewhere public can protect you while still showing you’re cooperating.

Scope note

This is first-steps guidance for the moment you’re being signalled to stop. If anything about the encounter later feels improper or threatening, consider reporting it once you’re safe.

Important note

This is general information, not legal advice. Prioritise road safety and personal safety, and follow lawful instructions once you have reasonable confirmation you are dealing with genuine police.
