How can I lookup police impounded and pink/yellow/green “stickered” status for a vehicle?

Unfortunately there is no database available for CarJam or the public to search regarding vehicle impounds or status/presence of green, yellow or pink stickers attached to vehicles.

If you have a specific question regarding Police involvement with a vehicle you should refer that question to your local police
