Understanding driver fatigue and how to reduce it

Driving fatigue is a state of reduced mental and physical alertness that significantly impairs driving ability. It's often described as tiredness, weariness, sleepiness, or exhaustion experienced while driving.

Fatigue driving increases the risk of accidents and is considered as dangerous as driving under the influence of alcohol.

Signs of fatigue while driving

When driving, it’s important to be aware of signs that can compromise safety.

• Feeling sleepy impairs your ability to stay alert on the road.

• Heavy eyelids lead to reduced visibility and focus.

• Difficulty concentrating causes you to miss hazards or traffic signals.

• Distorted perception makes you misjudge your car’s speed or how far you are from other vehicles.

• Delayed reactions affect your ability to avoid hazards or quickly process changes in road conditions.

Common causes of driving fatigue

Several factors can contribute to drowsy driving.

• Lack of sleep is the primary cause of driver fatigue, as it affects your alertness and concentration.

• Extended driving without breaks leads to mental and physical exhaustion.

• Driving late at night disrupts your natural sleep patterns and contributes to drowsiness.

• High levels of stress drain energy, making it challenging to maintain focus on the road.

• Vehicle noise, vibration, and harshness create discomfort and distraction while driving.

Reducing drowsy driving requires attention to both your driving habits and your vehicle's condition. While personal strategies like getting adequate rest and taking regular breaks form the foundation of fatigue prevention, your vehicle's equipment and maintenance also play a role in creating a comfortable driving environment.

Prioritise rest for safe driving

Getting sufficient sleep is vital for safe driving, especially on long trips. If you're planning to drive a significant distance, consider going to bed earlier so that you are well rested and aim to drive during the hours you are normally awake to ensure you stay alert.

Additionally, it's important to take a 15-minute break every two hours and stretch to help maintain alertness and reduce fatigue. Don't eat too much before or during your trip, as heavy meals can increase drowsiness. If possible, switch drivers with a friend or family member to share the responsibilities of driving, allowing both of you to stay refreshed throughout the trip.

While driving, keep your car well ventilated and at a comfortable temperature, and avoid staring at the centreline of the road all the time to prevent eye strain and maintain alertness. If you are getting tired while driving, pull over and rest or switch drivers.

Create a comfortable driving environment

Beyond staying rested and taking breaks while driving, certain vehicle equipment and maintenance can also help reduce fatigue.

• Maintain proper tyre pressure and alignment for a smooth ride. Keeping your tyres properly inflated prevents a stiff, bumpy experience, while regular wheel alignment and balancing reduce vibrations that can contribute to fatigue driving over long distances.

• Choose quality suspension components to minimise road harshness. Well-maintained shock absorbers and struts help your vehicle handle bumps and road imperfections smoothly, reducing the physical strain on your body during extended driving.

• Ensure your seat is properly adjusted and consider ergonomic accessories like lumbar support cushions to maintain comfort and reduce back strain during long drives.

• Opt for low-noise tyres to create a quieter cabin environment. Tyres with specially designed tread patterns can significantly reduce road noise, allowing you to concentrate better without the distraction of excessive noise.
