Operating a motor vehicle demands energy, focus and stamina when travelling longer distances. Cars are designed to relief the driver of as much stress as possible to reduce fatigue. A less fatigued driver is also a safer driver. The seating position for the driver’s seat plays a major role in fighting fatigue.
When adjusting the driver seat, you should look into the following settings:
The distances to the steering wheel and pedals should be as such that they can be reached comfortably. When placing the hands at the “10 past 2” position, the arms should not be fully stretched out and straight but slightly bent. You should be able to reach all stalks, switches and buttons needed to operate the vehicle. Your feet should be placed firmly on the floor without having to shift in the seat when pressing either one.
It is important to maintain at least 10–12 inches (25–30 cm) of distance between your chest and the steering wheel for proper airbag deployment safety.
The seat height should be set in a manner so that the hips are at least level with, or slightly higher than, your knees. This is to ensure the spine's natural curve and to promote blood circulation. Ensure you have a clear view of the road and instrument panel. Often forgotten in this context, the mirrors should also moved into clear view by way of adjusting the seat. Moving or craning one’s neck to get the mirrors into the driver’s field of vision can potentially be risky as the road might be out of view.
When observing those who drive commercially (Bus drivers, truckers or taxi drivers) one will notice that they set the backrest almost upright. A decline to a slight angle of approximately 100–110 degrees is recommended. This helps distribute pressure evenly along your spine, ensures your shoulders are relaxed, and prevents slouching. If your backrest features one, you should adjust the lumbar support to fit snugly into the natural inward curve of your lower back. If you feel pain, it is not correctly adjusted. You can use a small cushion or a rolled-up towel for support should your car not come with a lumbar support.
It may block the view from the passengers in the back, but the headrest actually plays an important role in your car. It is a personal protection device in essence. It should be adjusted to be as close to the back of your head as possible, to about 6 – 10 cm away. This is to prevent whiplash in a collision.
Position the headrest so the top of it is level with the top of your head (or at least your ears).
