Final answer:
For driving in reverse, the recommended hand placements are either at 12 o'clock or at 6 o'clock on the steering wheel, depending on the specific situation and level of control required.
Step-by-step explanation:
When driving a vehicle in reverse, the recommended hand placement for maintaining control and being able to look back comfortably is usually either 12 o'clock on the steering wheel with one hand, or with one hand at 6 o'clock if needing to turn the wheel substantially. However, opinions vary with different driving schools and countries. For example, when placing your hand at 12 o'clock, you would place your left hand on the top of the steering wheel and turn to look over your right shoulder through the back window, using the right hand to guide the wheel if necessary. This method is often taught for its simplicity and because it allows a clear view through the rear window. On the other hand, the 6 o'clock position may be preferred in some driving techniques for more precise control while turning at low speeds. This answer is based on the general conventions of driving and may not be the only correct method as techniques can vary based on location and specific instruction.
