Final answer:
When parking UPHILL with a curb, turn the wheels away from the curb and use the parking brake. These precautions prevent the vehicle from rolling down the hill and are often legally required.
Step-by-step explanation:
When parking UPHILL against a curb, it's important to take certain safety precautions to ensure that your vehicle doesn't roll down the hill. First, you should always turn your wheels away from the curb so that if your vehicle begins to roll, it will roll into the curb which will help stop it from moving further. This is a basic rule that is part of safe driving practices taught in driver's education.
Additionally, you should always engage your parking brake when parking on an incline to provide extra security against your vehicle rolling. In some areas, it is also legally required to turn your vehicle's wheels in a specific direction when parked on an incline with a curb. Therefore, not only is this a safety measure, but it's also often a legal requirement.
