A driver is parking a passenger vehicle facing uphill on a steep two-way roadway bordered by a raised concrete curb on the right side. To ensure maximum safety and prevent the vehicle from rolling into moving traffic lanes if the mechanical parking brake fails, how should the driver position the vehicle's front wheels?
- Turn the front wheels sharply to the left (away from the curb) and allow the vehicle to roll back slightly until the rear edge of the front tire touches the curbAnswer
- BTurn the front wheels sharply to the right (toward the curb) so that the front edge of the tire rests against the curb face
- CKeep the front wheels pointed straight ahead parallel to the curb to maintain steering alignment
- DTurn the front wheels to the right (toward the curb) only if the incline exceeds a ten percent grade
Answer
The driver should turn the front wheels sharply to the left (away from the curb) and allow the vehicle to settle so the back of the front tire rests against the curb.
When parking facing uphill where a raised curb is present, turning the front wheels to the left (away from the curb) creates a safety mechanism. If the parking brake fails, gravity pulls the vehicle backward, causing the back edge of the front tire on the curb side to roll directly into contact with the curb, which stops the vehicle from moving into traffic.
