Final answer:
The correct technique for steering while backing up involves using the hand-over-hand or one-hand method at the bottom of the steering wheel, turning it in the direction you want the vehicle's rear to go.
Step-by-step explanation:
When steering a vehicle in reverse, the correct technique involves using the hand-over-hand or the one-hand method. For the hand-over-hand method, you should place one hand on the steering wheel and turn it in the direction where you want the rear of the car to go while the other hand assists in managing the wheel. For the one-hand technique, the hand should be placed at the bottom of the steering wheel, and to move the vehicle's rear to the right, you would move your hand to the right and vice versa for the left.
Always make sure to check your mirrors and over your shoulder for any obstacles or hazards before and during the maneuver. Additionally, it is advisable to reverse slowly to maintain control over the vehicle.
