You have a body clock called a ‘circadian rhythm’ that allows you to live a normal day-to-day life by planning when you should be awake and asleep. Your body clock makes you tired when you should be asleep and can be very dangerous when driving.Fatigue is the feeling of being tired, sleepy or exhausted and is a major cause of crashes
Fatigue affects everyone regardless of driving experience, but experienced drivers are often better able to avoid fatigue by knowing when to take a break.
Fatigue can slow your reflexes, affect your attention, affect your judgement, and cause you to fall asleep at the wheel.
The only way to stop fatigue is by getting enough sleep, and the only way to treat driver fatigue once you have started driving is to stop and rest.Take regular breaks to avoid fatigue
Not sleeping for 17 hours has the same effect on driving as a BAC of 0.05, and not sleeping for 24 hours has the same effect as a BAC of 0.10.
Some early signs of fatigue:
Make sure to take breaks every two hours. If you feel tired or notice any of these early signs of fatigue - STOP AND REST!
Typical situations when fatigue can happen:
Driving while tired can cause microsleeps. Microsleep is a short, unintended loss of consciousness characterised by briefly closing the eyes, head snap
At 100 km/h, a 1-second microsleep means that the car will travel about 28m without the driver having any control.
To avoid fatigue:
Driver Reviver sites are places where you can take a break during peak holiday travel periods (e.g. Christmas and Easter). They provide free coffee, tea, snacks and road advice.
Rest areas are places where you can stop and revive before continuing your journey. They are open 24/7.
You can also take breaks at petrol stations, parks etc.
