When backing up, hold the steering wheel firmly with one hand in what position?

Answer: D — 12 o'clock

The correct position for holding the steering wheel with one hand while backing up is at the 12 o'clock position. This position provides optimal control and visibility for the driver. When the steering wheel is held at 12 o'clock, it allows for quick and precise adjustments while reversing, which is critical for navigating safely in reverse. It also helps maintain a good posture and balance, ensuring that the driver is well-positioned to observe the surroundings and react appropriately to any potential hazards. Other positions, such as 2 o'clock, 3 o'clock, or 10 o'clock, may not offer the same level of control and response ability when reversing, as they limit the driver's ability to easily turn the steering wheel or look over their shoulder effectively. Maintaining proper hand placement at 12 o'clock helps ensure that the driver can make smooth, controlled turns while simultaneously scanning the environment for obstacles or pedestrians.
