What to do if…
you are pressured to pull over by a suspicious incident or unmarked vehicle

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Slow down, switch on your hazard lights, drive predictably, and call 911 hands-free to explain that a suspicious or unmarked vehicle is trying to stop you. Ask the dispatcher whether an officer is attempting the stop and follow their instructions about where to pull over.

Do not do these things

  • Do not speed up, drive erratically, or try to outrun the vehicle.
  • Do not stop in an isolated place solely because an unknown driver gestures or pressures you.
  • Do not handle your phone while driving if you cannot do so safely.
  • Do not leave your vehicle to confront or inspect the other person.
  • Do not make sudden movements once you have stopped.
  • Do not give money, financial information, passwords, or an unlocked phone to someone claiming to be an officer.
  • Do not ignore instructions from the 911 dispatcher or an officer whose identity has been verified.

What to do now

  1. Switch on your hazard lights to show that you have noticed the vehicle. Slow to a steady, lawful speed and continue without sudden turns or other unpredictable movements.
  2. Call 911 using hands-free calling, or ask a passenger to call. Say that a suspicious or unmarked vehicle is pressuring you to pull over.
  3. Give the dispatcher your location, direction of travel, vehicle description, and any license plate or identifying details you can observe without distracting yourself.
  4. Ask whether a legitimate officer is attempting to stop you and where you should pull over. If the dispatcher confirms the stop, stop as directed.
  5. If the location is isolated or the dispatcher cannot immediately confirm the vehicle, explain your concern and continue carefully toward a nearby well-lit, populated place while following the dispatcher’s instructions.
  6. If another motorist has no clear emergency lights or siren but gestures for you to stop, claims you struck their vehicle, or says something is wrong with your car, keep your doors locked and tell 911. Do not negotiate or investigate on an isolated roadside.
  7. Once stopped, keep your hands visible and turn on the interior light at night. Until the person’s identity is clear, keep the door locked and lower the window only enough to communicate.
  8. If the person is not clearly identifiable, calmly ask for their agency name, badge, and agency-issued photo identification. You may also ask the dispatcher to verify the person or request a uniformed officer in a marked vehicle.
  9. If anyone tries to force entry, threatens you, or creates an immediate danger, tell the 911 dispatcher at once and follow their emergency instructions.

What can wait

You do not need to decide now whether to challenge a citation, make a complaint, contact a lawyer or insurer, post about the incident, or investigate the vehicle yourself. First reach a safe stopping place, verify who is involved, and let the immediate encounter end safely.

Important reassurance

Legitimate law-enforcement officers may use unmarked vehicles, but it is still appropriate to communicate your concern and ask 911 for verification. Slowing down, signaling that you have seen the vehicle, and following dispatcher instructions can help you avoid both panic and sudden escalation.

Scope note

This guide covers immediate safety steps only. Questions about a citation, collision claim, officer conduct, suspected impersonation, injury, property damage, or later reporting may require help from the relevant local agency or a qualified professional.

Important note

This is general safety information, not legal advice. Traffic-stop duties, emergency-light rules, and law-enforcement procedures vary by state and locality, so follow lawful instructions from the 911 dispatcher and verified officers.
