Make sure to lock your car doors when you’re in bear country.

The Boulder County Sheriff’s Office posted a dramatic reminder of what can happen when you forget. In a Facebook post, the department shared a photo of a car that had been inadvertently totaled by a bear.

On Thursday night, a bear pulled open an unlocked driver’s door and climbed into a car. The door shut behind it, and the bear attempted to dig itself out.

It then “butt-shifted” the car into neutral, and it rolled backward off a driveway and 100 feet down a hill.

The car swiped a tree on the way down, popping a door open. Good news for the bear, bad news for the car, which is now undrivable.

Living in Colorado can mean coming into close contact with bears from time to time. To prevent damage to you or your vehicle, wildlife experts recommend always keeping your car locked and not keeping food or other strong smelling items in your car.
