What is a police marker?
Why do the Police place markers on a vehicle?
1. A negative report about a vehicle
2. Theft markers
Escape the buyers remorse
3. Drug and drug-related offenses
If the police find drugs on a vehicle, they usually place a marker on it. They may also mark a vehicle if the driver is found drunk or involved in drunk driving.
The police place this marker because it is presumed possible to find drugs on the vehicle in the nearest future.
