3. Don’t leave valuables inside your car.
A car which has valuables within plain view is always a target for car thieves. Don’t leave any personal documents, credit cards or cash inside your vehicle. If you have to store valuable items in your car, make sure that you put them in the trunk, or at the very least, hide them from plain sight. Keep in mind that stowing your valuables at your destination and then leaving your car in the parking lot can also be tempting for thieves who may be watching from the other side of the lot – so whenever possible, store your valuables before arriving at your destination.
