Who is responsible to remove derelict vehicles off my property they don't belong to me?

Typically, the responsibility for removing derelict vehicles from your property falls on the property owner, even if the vehicles do not belong to you. You can report the issue to your local government or municipality, which may have specific ordinances regarding abandoned vehicles. They may send a code enforcement officer to assess the situation and take appropriate action. Additionally, you may want to contact local law enforcement if the vehicle poses a safety hazard.
