Question

Difficulty: HardParking, Standing, and Stopping Regulations

A driver parks a vehicle on a narrow rural road facing downhill on a steep grade with no raised curb along the roadway edge. To ensure the vehicle remains safely secured and prevented from rolling into traffic if the mechanical parking brake fails, which combination of actions must the driver take before exiting?

  1. Turn the front wheels sharply toward the right (toward the side of the road), firmly engage the parking brake, and place the transmission in Reverse (or Park for automatic).Answer
  2. B
    Turn the front wheels sharply toward the left (toward the center of the road), firmly engage the parking brake, and place the transmission in Low gear (or Park for automatic).
  3. C
    Keep the front wheels pointed straight ahead, firmly engage the parking brake, and leave the transmission in Neutral.
  4. D
    Turn the front wheels sharply toward the right (toward the side of the road), release the parking brake slightly to settle tire tension, and place the transmission in First gear.

Answer

Turn the front wheels sharply toward the right (toward the side of the road), firmly engage the parking brake, and place the transmission in Reverse (or Park for automatic).
When securing a vehicle parked downhill on a road without a curb, turning the front tires to the right directs any unintended forward motion off the road onto the shoulder. Combining this tire orientation with a fully set parking brake and engaging Reverse gear (or Park) provides complete mechanical redundancy.

Step-by-Step Solution

1
Determine wheel direction relative to roadway edge and grade direction.
Facing downhill, front wheels must be turned toward the right (edge of the road) so any forward roll directs the vehicle away from traffic.
Without a curb to catch the tire, turning right ensures the vehicle rolls off the roadway onto the shoulder or embankment.
2
Determine appropriate transmission gear for downhill parking.
Select Reverse for manual transmission (or Park for automatic transmission).
Reverse gear provides maximum mechanical engine resistance against forward downhill motion.
3
Apply secondary holding mechanisms.
Fully engage the mechanical parking brake.
The parking brake acts as the primary stationary holding device to lock the rear wheels.
