For property that does not have serial number, mark it with an engraver or other device with identifying marks. Do not use social security numbers or other personal information as an identifying mark.
Always lock your vehicle and keep your windows rolled up. An unlocked vehicle is an easy target for thieves, even when it is parked in your driveway.
Park in well lit areas.
Don’t leave anything in plain view in your vehicle that appears that it might be valuable (backpacks, bags, etc.). Thieves will break a window to take a backpack, even if it doesn’t have anything valuable in it. They don’t know it isn’t valuable.
