What to do if…
you find an unfamiliar item placed on your car like a note, tag, or object you did not leave

Short answer

Move to a safer place and assess from a distance. If the item looks attached, bulky, tampered-with, or clearly out of place, don’t touch the item or the car—move away and call 911.

Do not do these things

  • Don’t touch, open, move, or peel off anything that looks attached (magnet/tape/box/wires) or out of place.
  • Don’t get into your car if you feel watched, followed, or boxed-in—step back and change location first.
  • Don’t confront someone you suspect placed it, and don’t respond to a note with personal info.
  • Don’t drive the car away if you suspect something has been attached to it (especially underneath or near the wheels/engine area).
  • Don’t post photos online that show your license plate, home street, regular workplace, or other identifying details.

What to do now

  1. Make yourself safer first (before you “solve” it).
    Go into a nearby store/building, stand in a well-lit busy area, or ask staff/security to stay with you.

  2. Look without touching (10–20 seconds). Decide which of these it is:

    • A loose paper note/flyer/tag (under wiper, hanging, resting on the car), not connected to the vehicle.
    • Something attached or “installed” (taped/magnetized object, device, wires, box, anything placed underneath, or anything you can’t identify quickly).

  3. If it’s attached / bulky / suspicious: treat it as unsafe.

    • Do not touch the item or the vehicle.
    • Move away and keep others back.
    • Call 911 and describe your exact location and that there’s an unknown item on your vehicle that appears attached/under the car.

  4. If it’s a loose note/tag and nothing suggests immediate danger:

    • Photograph it in place (wide shot + close-up).
    • Write down details: time, location, who was with you, anything you noticed nearby.
    • If you’re on a property with cameras (store, garage, managed lot), ask staff/security to preserve footage for the relevant time window and note who you spoke to.
    • If you might report later, remove it with minimal handling (tissue/gloves if available) and seal it in a bag/envelope.

  5. Do a quick sweep before you get in.
    Walk once around the car and look for anything new: under wipers, door handles, wheel wells, under bumpers, unusual tape/magnets, or something wedged near the gas cap. If anything seems attached, step back and follow Step 3.

  6. Check for signs of unwanted tracking on your phone (1–2 minutes).

    • If you get an alert about an unknown tracker, save screenshots.
    • If your phone offers it, run a manual “unknown tracker” scan.
      This won’t detect every possible tracker, but it can catch common Bluetooth item trackers.

  7. If you think you’re being targeted (repeat incidents, targeted message, someone lingering):

    • If you’re in immediate danger or being followed: call 911.
    • Otherwise, call your local police non-emergency number to make a report and ask for a case/report number.
    • If you suspect your phone might be monitored, consider using a safer device/account to reach help (so you don’t escalate risk by tipping someone off).

  8. If you want confidential victim support without having to “decide what this is” yet:
    Contact VictimConnect for confidential support and referrals in the U.S. (phone/text/chat options).

What can wait

  • You do not need to figure out who did it or why right now.
  • You do not need to decide immediately whether this “counts” as stalking or a crime—focus on safety and preserving options.
  • You do not need to make big life changes in this moment (moving, changing jobs, changing routines) unless there’s an ongoing pattern and you have support.

Important reassurance

Feeling alarmed is a normal response. Many items on cars are harmless (flyers, mistakes), but it’s reasonable to treat an unfamiliar attached object or a targeted message as a safety issue until proven otherwise.

Scope note

This is first-steps guidance for the next few minutes. If this becomes a pattern, you may need a more detailed safety plan and victim-support guidance tailored to your location.

Important note

This is general information, not legal advice. If you believe you are in immediate danger, call 911.
