When is the only time you should not use your parking brake when parking on a hill?

• A. When there is a slight grade
• B. When it is extremely cold outside
• C. When parking briefly
• D. When you are stopping for a moment

Answer: (B)

When parking on a hill, you use the parking brake to keep the car from rolling and to provide a secure hold while you’re parked. The one time you should not rely on it is when the weather is extremely cold. In very cold conditions, moisture can freeze inside the parking brake mechanism, causing it to seize or stick and making it hard or impossible to release. If the brake might freeze, it’s safer to hold the vehicle with the transmission (and, if possible, wheels chocked) rather than depending on the parking brake. In all other scenarios, such as a slight grade, a brief stop, or a short parking moment, engage the parking brake as part of a proper holding routine.
