What is the safest method for ensuring your vehicle does not roll away when parked downhill?

The safest method for ensuring your vehicle does not roll away when parked downhill is to turn the front wheels towards the curb, leave it in gear or park, and apply the handbrake. This approach combines several safety measures:

1. Turning the Wheels: By turning the front wheels towards the curb, if the vehicle does start to roll, the tires will make contact with the curb, which can help to stop the vehicle from moving further down the slope. This action serves as a physical barrier to prevent rolling.

2. Leaving in Gear or Park: Putting the vehicle in gear (for a manual transmission) or in the 'Park' position (for an automatic transmission) helps to lock the transmission, which adds an additional layer of security against movement. This prevents the vehicle from rolling away if other measures fail.

3. Applying the Handbrake: Engaging the handbrake firmly ensures that the rear wheels are securely held in place. This brake is specifically designed to keep the vehicle stationary, even on inclines. A properly functioning handbrake is essential in preventing the car from rolling.

Together, these actions create a comprehensive safety strategy to minimize the risk of the vehicle rolling away, especially in downhill situations.
