8. Adjust the head restraints. Place the headrest to a height just above your eyelids, and (more importantly) — as close to the head as possible (2-3cm). A head-restraint further than 7cm increases the risk of whiplash. Keep in mind that while driving our head bends forward a bit more. If you cannot adjust the head-restraint to the proper distance, you need to compensate by increasing the backrest tilt.
9. Make additional adjustments as necessary.
- Lumbar support: Should provide equal pressure across the whole length of the back. For drivers with lumbar problems without such an adjustment, you can use one or two rolled towels.
- Side Bolsters: Should be adjusted for the maximum possible hip support without limiting the ability to depress all pedals fully.
- Seat base reclining: Should keep the thigh in full contact with the seat. Avoid too much reclining which will create pressure behind your knees, or interfere with strong braking (you should not apply pressure against the seat).
- Pedal adjustments: Should allow operation of the pedals as described above as comfortably as possible. You should be able to place your heel roughly in front of the brakes, place your foot on the brakes with the slightest possible offset to the right, and pivot as easily as possible towards the throttle pedal on the right, while keeping your knee bent at about 100 degrees.
10. Position your hands properly. Your hands should both be on the wheel, at the 9 and 3 position. This increases the leverage on the wheel to a maximum. Your palms should be placed against the outer diameter of the wheel and the thumbs should be lightly hooked on the cross-brace of the wheel.
- Grip and stabilize the wheel not only with the thumbs and/or palms, but mainly with your fingers and fingertips. In general, keep the grip of the wheel as light as possible without losing your control over the wheel. This results in better control and less fatigue.
- Keep both hands on the wheel. Steering with one hand makes the weight of the hand work on the wheel, for which the shoulder muscles must be used to keep the wheel steady, resulting in a twist of the spine, especially if you get into the (bad) habit of holding the wheel from its top.
11. Wear your seat belt properly. Adjust the lap-belt as snugly as possible over the waist. The belt should be physically tightened and placed as low as possible, on the pelvic bones, rather than the soft belly.
- The shoulder strap should be adjusted to the height, so that the mounting is higher than the shoulder, and that the strap itself is placed over the acromion (middle of the shoulder), which is felt as a socket midway between the arm and neck.
- If the shoulder strap is placed on the neck or even on the collar bone (clavicle), it is too high and will cause fractures to the clavicle and cuts the neck.
- If the strap is placed too low on the shoulder itself or on the arm/under the armpit, it will not support the body and cause severe cuts to the arm.
- All passengers should be strapped, and little children need to be harnessed in the suitable child seats and boosters. There are also special straps for pets. There are also other points that are worthwhile for the passengers:
- Head restraint adjustment
- Window adjustment
- Proper placing of limbs relative to airbags: Avoid placing feet over the passenger’s airbag or placing hands in the way of the lateral or curtain airbags, etc…
- Proper distance from the dashboard
- Full and erected seating: Full contact of the back and the seat, and an erected rake angle for the front passenger, to avoid “submarining under the lap belt.
- Awareness: Falling asleep is dangerous for passengers. The front passenger should be awake to monitor and assist the driver, and to avoid acute abdominal injuries in a collision, which are intensified when the person is asleep.
Not all seats of the car are equally safe. The middle-rear seat is considered safest, followed by the seat behind front passenger seat, than the seat behind the driver, the front passenger seat and the driver being in the greatest threat. This division changes in cars with additional seats (minivans) or when the middle-back lacks a diagonal or adjustable belt or a head-restraint.
12.Check your visibility. With this position, your eyes will be placed in front of the center or upper half of the glass for improved visibility. Keep your eyes relaxed rather than trying and focus, and keep the eyes up rather than down. You will see more and further away, while still being aware of your surrounding with your peripheral vision.
- Adjust your mirrors to give you a broad field of vision to the rear and sides (see in links below) at the glance of an eye or a slight tilt of the head (if you have a narrow field of vision due to illness or age). In some cars, you might also need to be ready to lean slightly forward or take a slight peek to the side (“Shoulder check”) to make sure you see everything around while driving.
13. Keep objects in the car low, on the floor, preferably at the front seat. Do not keep anything around the driver’s seat, because it might slip under the pedals.
- In general, anything not stock is not wanted: A convex mirror mounted on the center mirror, a padded cover of the steering wheel, things dangling about on your rear-view mirror — these are all bad things that can also prove hazardous in an accident.
- Windows, in this respect, are best either completely closed, slightly opened or almost fully opened, rather than half-way down, in which case the head of the driver or one of the passengers might hit it. Always keep one of your front windows slightly opened for fresh air.
- Open windows on highways can create drag that impairs fuel consumption and even the stability of the car, so it’s best to only keep one or two windows slightly opened at most.
- On rugged terrain, the windows should be fully closed or fully opened to avoid rocking the window’s bushings.
- Windows, lights and spectacles should be kept clean.
14. Adjust your rear-view mirrors to a minimal overlap and maximal visibility.
- While it is possible to fit a quality, vacuum-adhesive interior mirror to view the back seat, in long drives with the whole family, it’s best for the front passenger to be the one in charge of the inside of the car, and for the driver to focus himself on the road. Do not adjust your stock interior mirror to see the back seat and do not use wide-angle convex mirrors as well.
Likewise, avoid placing a child in the front seat, regardless of child restraints or airbags.
15. Use the air-conditioning to demist fumes on the windshields, and to provide a comfortable environment. It’s better to use the car heat in the winter instead of driving with heavy clothing that interferes with steering and with the function of the seat belt. Keep one window slightly open for fresh air both in the summer (for oxygen) and winter (for fresh cold air).
- The air conditioning is there to be used — open the A/C periodically, even in the winter, and open the heating periodically — even in the summer — to ensure proper mechanical function of the two over time.
- A/C air recirculation is very efficient because is blows large amounts of air. However, you need some fresh air through the driver’s window. Likewise, if the windscreen is very heavily misted, opening the A/C for fresh air (along with an open window) can do better. Using external circulation is also efficient when you try to cool down a very hot cabin before entering it.
- The A/C can also clear out bad smells. A few minutes before you turn off the car, close the air conditioner and air circulation, but keep the fan blowing air. This will channel out waste in the air ducts via a little hose inside it. Likewise, in a hot summer day, it’s worthwhile to keep the heating blowing full time with all windows and doors open, to refresh the cabin.
- The heating is also a good choice for when the engine starts to overheat. In highways, stopping on the hard-shoulder is so perilous that it is better to keep on driving towards a safe stopping place, even in the price of causing damage to the car (like overheating the engine). Using the heating to disperse engine heat can help reaching a safe stopping place without the engine reaching critical levels of heat.
