What action should a driver take immediately before exiting a vehicle parked on a hill?

When a driver prepares to exit a vehicle parked on a hill, it is essential to take specific actions to ensure both their safety and that of other road users. Turning off the ignition is necessary to prevent the vehicle from accidentally rolling away, as the engine should be off when exiting. Setting the emergency brake is crucial because it provides additional security by immobilizing the vehicle and reducing the risk of it rolling down the hill. Finally, turning the wheels is a critical step as well – if the vehicle is parked facing downhill, the wheels should be turned toward the curb, and if parked uphill, they should be turned away from the curb. This practice helps ensure that if the vehicle does start to roll, it will roll into the curb rather than into traffic.

Combining all these actions—turning off the ignition, setting the emergency brake, and turning the wheels—creates a comprehensive safety procedure that helps to prevent accidents and ensures the vehicle remains securely parked. Therefore, selecting all of the actions taken together is the most complete and safe practice for exiting a vehicle on a hill.
