Difficulty: MediumParking, Standing, and Stopping Regulations

A driver brings a vehicle to a complete stop facing uphill on a road that lacks a raised curb along the shoulder. To prevent the vehicle from rolling into oncoming traffic if the parking brake fails, in which direction should the driver turn the front wheels?

  1. To the right, toward the edge of the roadAnswer
  2. B
    To the left, toward the center of the roadway
  3. C
    Straight ahead, parallel to the road shoulder
  4. D
    Toward the left shoulder regardless of traffic flow

Answer

The front wheels should be turned to the right, toward the edge of the road.
When parking on an incline (uphill or downhill) where there is no curb, the driver must always turn the front wheels toward the right side/edge of the road. This ensures that if the vehicle starts to roll due to brake failure, it will roll away from active traffic lanes and come to a rest off the roadway.

Step-by-Step Solution

1
Identify the hill orientation and curb presence
The vehicle is facing uphill on a grade without a curb.
Curb presence determines whether tires can be blocked by a curb or must steer the vehicle off the roadway entirely.
2
Determine the rolling trajectory if the parking brake fails
Without a curb, turning wheels right forces the rear of the vehicle to roll off the road away from traffic.
If wheels are turned left without a curb, a backward roll directs the vehicle straight into active traffic lanes.
