When should you use the parking brake?

• A. Every time you leave the vehicle
• B. Only when loading
• C. Only on hills
• D. Never

Answer: (A)

Always set the parking brake whenever you leave the vehicle. This simple habit keeps the truck from rolling away, even on level ground, and provides a second safeguard beyond the service brakes in case of a transmission or brake issue. It’s especially important on hills or ramps, but relying only on the parking brake in those situations isn’t sufficient if you forget to use it routinely. Release the parking brake before moving again to avoid a sudden pull and extra wear. The other options miss the essential safety practice of securing the vehicle every time you park.
