The police can seize a vehicle if they think it’s being used in a way that causes alarm, harassment or distress, for example careless or inconsiderate driving.
They can also seize a vehicle if they think it’s:
being driven by someone who does not have a proper licence or insurance
dangerously, illegally or obstructively parked
broken-down or abandoned
If your vehicle is seized there’s a ‘release fee’ of up to £200 plus a storage fee of £20 for every day or part day.
