Final answer:
Proper hand position on the steering wheel is achieved by placing hands at the 9 and 3 o'clock positions with a relaxed grip, which assists in control and reduces fatigue. Supination and pronation should be considered for ergonomics and comfort. Techniques like hand-over-hand or push-pull help with sharper turns.
Step-by-step explanation:
Proper hand position while holding the steering wheel is essential for safe driving. Generally, it is recommended to position your hands on the steering wheel at the 9 o'clock and 3 o'clock positions, as if on a clock face. This positioning aids in maintaining control while steering and allows for smooth turning of the wheel without having to cross arms, which could be dangerous. It is also important to keep your grip relaxed on the wheel to avoid fatigue and maintain better control.
Techniques like the hand-over-hand or push-pull methods might be taught in driver's education courses when making sharper turns. These techniques allow for full control of the steering wheel during a turn while keeping both hands on the wheel at all times. In addition, making sure your hands and wrists are positioned for correct ergonomics will assist in reducing the potential for fatigue or injury over long drives.
Supination and pronation are terms related to forearm movement. When your palm faces upward in a supinated position, it can help with the overall ergonomics of holding the steering wheel. Make sure to adjust your grip and seat positioning so that your forearms and hands do not have to excessively pronate or supinate, leading to discomfort or decreased control.
