What is the incorrect thing to do if you cause damage to an unattended vehicle?

Make every effort to find the owner of the vehicle

Contact your insurance company

Leave a note for the owner with your name, address, and vehicle plate number

Leave the scene immediately without notifying anyone

It is incorrect to leave the scene immediately without notifying anyone, and in most states it is considered a crime as you are fleeing the scene of a crime. You should make an effort to locate the vehicle's owner, you should contact your insurance company, and you should certainly leave a note for the owner with all of your information.
