What is the parking rule for downhill parking along a curb in Indiana?

When parking downhill along a curb in Indiana, turning your front wheels toward the curb is the correct approach to ensure the vehicle does not roll into traffic if it were to slip out of gear or be involved in an accident. By positioning the front wheels toward the curb, the vehicle will likely be prevented from rolling directly into the street, as the curb acts as a barrier. This practice enhances safety for both the parked car and surrounding traffic.

The other choices, while they might involve safe parking practices, do not align with Indiana's specific laws regarding downhill parking. For instance, leaving the vehicle in neutral would potentially allow it to roll away if not properly secured. Parking with the tires against the curb is misleading since it does not specify the necessary wheel positioning for downhill parking. Therefore, the recommended method is to turn the wheels toward the curb when parked downhill.
