Truck Ergonomics: Reducing Driver Fatigue and Injury

April 28, 2026

Key Takeaways:

• Seat positioning: Your knees should be level with your hips.
• Lumbar Support: Support the natural curve of your lower back to prevent slouching.
• Steering & controls: Prevent overreaching by keeping shoulders relaxed and elbows bent.
• Mirror adjustment: Set your mirror so that you don’t twist or lean.
• Pedal Reach: Adjust your seat so you can operate pedals without fully extending your legs.
• Regular breaks: Get out and stretch every 2 hours.
• In-seat movements: Try moving in your seat every hour for better circulation and posture.
• Fatigue monitoring: Stay alert. Use your truck’s in-cab monitoring to keep safe.
• Healthy habits: Stay hydrated and avoid sluggishness.
• Quality sleep: Get good sleep with blackout blinds, earplugs, and cab soundproofing.
• Vibration reduction: Choose a truck with air ride or hydraulic suspension seats.
• Task aids: Use tools to take the strain off your body.

It’s so important to keep your body healthy when you’re driving. But there’s a bit more to ergonomics than just getting out for the occasional stretch now and then. Your truck has a range of helpful, assistive features that help you stay at your best on those long drives. But there are also some things you should make sure you do, too. So, let’s take a look at them.

Ergonomic Cab Adjustments

Seat positioning:

The foundation of a healthy drive is how you sit. Position your seat so that your knees are level with or slightly lower than your hips. Ensure your thighs are fully supported by the seat cushion without the edge pressing into the back of your knees. To reduce spinal pressure, a slight recline of approximately 110 degrees is often more comfortable than sitting perfectly vertical.

Lumbar Support:

It isn’t just your legs that take the strain; your lower back is often the first place to feel the miles. Adjust the backrest so it fills the hollow of your lower back (the lumbar curve). If your seat’s built-in support isn’t hitting the right spot, a dedicated lumbar roll or firm pillow can help prevent the “slump” that leads to long-term injury.

Steering & Controls:

To protect your neck and shoulders, use your truck’s tilt and telescopic steering features. You want the wheel close enough that your shoulders remain relaxed and your elbows stay slightly bent. Overreaching for the wheel puts unnecessary leverage on your upper back and can lead to tension headaches. You can also use your Volvo truck’s tilt and telescoping features to find an even more optimal position for yourself.

Mirror Adjustment:

And now, the thing that you check every time you sit down in your cab: the mirrors. You likely already adjust your mirrors to your comfort, but now that you’ve checked everything else, be sure to set them. Hence, you have full visibility in your new ergonomic driving position. You don’t want to have to twist or lean while you’re driving at all, so use your mirror in a way that makes sure you don’t have to. Use adjusting your mirrors as a cue to sit up straight.

Pedals: 

While you can’t move the pedals, you can move the pilot. Adjust your seat’s forward/backward position so that you can depress the pedals fully while maintaining a slight bend in the knee. You should never have to “point” your toes or lock your joints to reach full travel.

Regular breaks: 

Just because your cab is now ultra-ergonomic doesn’t mean you can now spend all day in there! On longer journeys, try to limit continuous driving sessions to 2 hours. When you get out of your UD truck, take a short break to stand, walk around a little, and stretch before you sit back down.

In-seat movements: 

You don’t just have to get out to do your stretches – you can also shift your weight and adjust your position in your chair around every 30 or 60 minutes. Doing this will help with your circulation as well as your posture.

Fatigue monitoring:

Fatigue is extremely dangerous for a driver. That’s why we recommend you use technology to track your alertness. Many Isuzu trucks offer systems with in-vehicle monitoring for drifting or yawning, with real-time alerts.

Healthy habits: 

Fatigue isn’t the only thing you have to worry about on the road. Proper hydration is also important, as well as avoiding sluggishness. So, bring a water bottle with you, and avoid parking your Electromobility truck at that greasy spoon for heavy, greasy meals.

Quality sleep: 

It can indeed be difficult to get good sleep out on the road. But today’s modern Mack trucks offer many ways to make sleeping easier. A cab with soundproofing and blackout curtains can help you catch up on those REM cycles. You could also invest in earplugs or sleep headphones to ensure you get those 8 hours.

Preventing Injuries and Strain

Vibration reduction: 

Not every road is a well-maintained, smooth ride. Sometimes you have to drive over bumpy roads or potholes. When this happens, road vibrations can cause a surprising amount of back, neck, and shoulder pain. So, whether new or used, look for a truck with air-ride or hydraulic suspension seats.

Task aids:

Use tools like pin pullers, tyre steps, or tandem axle stoppers to avoid manual, high-force maneuvers, especially when your body feels stiff.

When it comes to high-force maneuvers, there are plenty of tools that can make the job a bit easier. Pin pullers, tyre steps, and tandem axle stoppers are all handy ways to reduce the strain on your body, especially if you’re feeling stiff.
