Why cant you take your car out of park?

On a newer car, the car's brake must be applied to get out of park. Most cars will not go out of park if the key is not in the "on" position. It may stick if it's very cold outside. In an older car, parking on a hill can cause the shift lever to stick in park.

To avoid the last one, apply the parking brake before shifting into park when parking your car on a hill.

To get the car unstuck from a car in park on a hill, rock the car up the hill while pulling the shifter.
