Back Care & Posture
86% of professional drivers report back pain. Hours of sitting in a vibrating cab compresses your spinal discs, weakens your core, and tightens your hip flexors. The good news: most back pain is preventable with the right habits.
Your seat is your office chair. Getting it right is the single most important thing you can do for your back. Spend 5 minutes setting up properly — it will save you years of pain.
1. Seat Height
Adjust so your hips are level with or slightly higher than your knees. Your feet should reach the pedals comfortably without stretching.
Too low = extra pressure on your lower back. Too high = your legs dangle and circulation suffers.
2. Seat Distance
Slide the seat so you can fully depress the clutch with a slight bend in your knee. Your back should stay against the backrest.
Too far = you lean forward and strain your back. Too close = cramped legs and poor circulation.
3. Backrest Angle
Set the backrest to about 100-110 degrees — slightly reclined from vertical. Not bolt upright, not lounging.
This angle puts the least pressure on your spinal discs. Sitting at 90° actually increases disc pressure by 40%.
4. Lumbar Support
Adjust the lumbar support to fill the natural curve of your lower back. If your seat lacks lumbar support, use a rolled-up towel or a £10 lumbar cushion.
Without lumbar support, your spine flattens and the muscles have to work overtime to hold you up.
5. Steering Wheel
Adjust the wheel so your wrists rest on top with arms slightly bent. Your shoulders should stay relaxed, not raised.
Reaching for the wheel causes shoulder and upper back tension. Too close causes cramped arms.
6. Mirrors
Set all mirrors so you can see them without twisting your body. You should only need to move your eyes, not your neck or torso.
Constantly twisting to check mirrors creates asymmetric strain on your spine.
The Numbers
Back pain is the leading cause of sickness absence in the transport industry. A study by the Health & Safety Executive found that professional drivers are 3 times more likely to develop chronic lower back pain than the general population. Whole-body vibration from the vehicle, combined with prolonged sitting, accelerates disc degeneration. However, regular movement breaks and targeted exercises reduce the risk by up to 50%.
