Driver fatigue is a significant problem, contributing to thousands of road accidents worldwide each year. Although it is impossible to calculate the exact number, research suggests that fatigue may be a factor in up to 20% of all crashes and as much as 25% of fatal and serious collisions.

Fatigue-related crashes are particularly severe, often involving high-speed impacts. When a driver falls asleep, they typically fail to brake or steer, resulting in devastating consequences.

Sleepiness substantially reduces reaction times – a critical element of safe driving – by impairing concentration and alertness. This diminishes our ability to make sound decisions behind the wheel, often with tragic results.

Alarmingly, most drivers are aware when they are feeling sleepy but continue driving instead of stopping to rest. Ignoring this common-sense decision often stems from a desire to ‘push through’ and complete the journey.

However, this behaviour can have dire consequences.

In some countries, including the UK, self-imposed sleep deprivation is now considered reckless driving and carries severe penalties.

When are you most at risk?

Fatigue-related crashes are most likely to occur:

During long, monotonous journeys, such as on motorways or other straight, low-traffic roads.

Between 2am and 6am, when the body’s natural alertness is at its lowest.

Between 2pm and 4pm, particularly after a meal.

After insufficient sleep or long working hours, especially following night shifts.

When alcohol or certain medications that cause drowsiness have been consumed.

Reducing the risks

To minimise the risk of fatigue-related accidents, consider the following tips:

Don’t start a journey when tired. Ensure you get a good night’s sleep before setting off on a long drive.

Avoid driving between midnight and 6am. This is when your circadian rhythm naturally lowers alertness.

Plan regular rest stops. Take at least a 15-minute break every two hours of driving.

Stop if you feel sleepy. Pull over in a safe place – never on the hard shoulder of a highway.

Be mindful of over-the-counter medicines, especially those for colds, flu, and hay fever, which can cause drowsiness. If the label says ‘may cause drowsiness’, assume it will!

Warning signs of fatigue

Recognising the signs of fatigue is vital to preventing accidents. These include:

Constant yawning.

Drifting between lanes.

Sore or heavy eyes.

Difficulty keeping your head upright.

Delayed reactions.

Daydreaming or losing focus.

Trouble remembering the last few kilometres driven.

Erratic changes in speed.

Staying Awake, Staying Alive

To combat driver fatigue:

Sleep well: Aim for 7-8 hours of uninterrupted sleep before a long journey.

Take regular breaks: At least 15 minutes every two hours, during which you should stretch and get some fresh air.

Share driving duties: If possible, alternate with a co-driver who is also well-rested.

Eat balanced meals: Stick to regular mealtimes.

Avoid sedating medications: Check labels carefully.

Time your journey wisely: Avoid late-night and early-morning drives when the risk of accidents is highest.

By following these simple rules, you can ensure you stay awake, alert, and safe behind the wheel.

Safe driving!
