Explanation:

Parking brakes should always be utilized when the vehicle is parked to ensure safety and prevent unintended movement. This is crucial regardless of the weather, the operational state of the engine, or the location of the vehicle. Using parking brakes helps secure the vehicle in place and is especially important on inclines or declines, where gravity could cause the vehicle to roll. The effectiveness of parking brakes can vary based on the vehicle's load and the surface it's parked on, but the standard practice is to engage them whenever a vehicle is parked to mitigate these risks. This habit enhances safety for the driver, passengers, and other road users, making it a vital aspect of vehicle operation and maintenance.
