Driver tiredness & fatigue

You should not drive while tired or fatigued. Drivers who are suffering from a lack of sleep are a danger to themselves and other road users.

If you are tired and fighting sleep, you are likely to experience 'micro sleeps'. These episodes can last up to 10 seconds and can be experienced even when your eyes are open.

During a micro-sleep of even four seconds, your car can travel 110 metres (more than the length of a football pitch) without you being in control of your vehicle.

In the past, driving when tired has resulted in the driver falling asleep, losing control of the vehicle, and causing serious injuries and fatalities.

Driving while tired or fatigued is not illegal. However, if you lose control of your vehicle and cause a crash you will be prosecuted.Picture of driver with eyes closed at wheel.
