Car Driving Ergonomics

Car Driving Ergonomics

Back pain and driving can’t be separated.  Sitting in the wrong position for long hours, gripping the steering wheel and being exposed to vibration from the roads can contribute to the back pain and shoulder pain. Humps and pot holes in road make sudden unexpected breaking and the same give more vibration in lower back and shoulder.

In recent years, majority of car provide wide range of adjustments. However, it is our duty to set our car parameters according to our own anthropometric measurements. Small adjustments can reduce the risk of back pain, neck pain and shoulder pain. 

Car adjustment:
  1. Start the ergonomic modification by getting the seat into the ‘initial set up position’, where adjustable:
  2. Steering wheel fully up and fully forward
  3. Seat height at its lowest
  4. Cushion tilted so that front edge in lowest position
  5. Backrest approximately 30 degrees reclined from vertical
  6. Lumbar support adjustment backed off
  7. Seat fully rearwards
  8. The car adjustment according to the ergonomic measure must be done according to the individual driver specific anthropometric measures.


Loughborough University guidelines & Chartered society of physiotherapy guidelines for car adjustment based on driving ergonomics


1. Step One – Seat height for better vision
    o Raise the seat as high as is comfortable to improve your vision of the road.
    o   Check you have adequate clearance from the roof.
    o   Ensure you have maximum vision of the road.

2. Step Two – Seat place for pedal comfort 
       o   Move the seat forwards until you can easily fully depress the clutch pedal and accelerator pedal. 
       o   Adjust seat height as necessary to give good pedal control.

3. Step Three – Avoid stress in leg
   o   Adjust cushion tilt angle so that the thighs are supported along the length of the cushion.
   o   Avoid pressure behind the knees.

4. Step four – Backrest is the best way to prevent back pain
       o  Adjust back rest so it provides continuous support along the length of the back and is in contact up            to  shoulder height.
o   Avoid reclining the seat too far as this can cause excessive forward bending of the head and neck and you may feel yourself sliding forwards on the cushion.

5. Step five – Lumbar support should be in lumbar curve
o   Adjust the lumbar support to give even pressure along the length of the back rest.
o   Ensure lumbar support ‘fits’ your back, is comfortable with no pressure points or gaps.

6. Step six – Steering wheel adjustment and avoid obstructions 
       o   Adjust steering wheel rearwards and downwards for each reach.
o   Check for clearance for things / knees when using pedals.
o   Ensure panel display is in full view and not obstructed.

7. Step seven - Head restraint adjustment to prevent head and neck injury 
       o   Adjust the head restraint to ensure the risk of injury is reduced in the event of a car accident

Repeat stages 1-7 and fine tune as necessary

Tips to prevent work related musculoskeletal injury for car drivers 
  1.  Never use your mobile phone while you are driving, use hand free to avoid neck pain  
  2.  Use seat belt irrespective of distance and speed, it can save a life during accidents
  3.   Adjust the rear view mirror and side mirror to avoid excessive and frequent  neck turning
  4.  Do adequate warm up before any sudden intense physical activity (such as lifting)
  5.  Keep the satellite navigation route system device away from your vision area
  6.  Keep spine straight and fully supported on seat while driving
  7.  Take a small break from driving every two hours
  8.  Do the simple stretch in every four hours
  9.  Avoid air condition if u has myo- facial pain, trigger points...
  10.  Use right hand in 2 o’clock and left hand in 10 o’clock position and avoid crossover of hand in steering wheel.
