One of the most important things you need to consider when going on a road trip is your safety. Your car is incredibly vulnerable to thieves, so it's always a good idea to know what to look out for. In fact, you should keep your eyes out for any pennies stuck in your door handles. It's been reported that thieves will do this as a way to stop you locking your car door.
If you can't lock your door, thieves will be able to steal anything from your car - or even the car itself. So, if you want to keep yourself safe, check for pennies before you lock your car.
