Fatigue can be defined as extreme tiredness caused by a lack of sleep, not enough rest or excessive mental or physical exertion. Despite this, most people underestimate what their body is telling them, and still get behind the wheel of a vehicle every day.
Sleep-deprived driving (commonly known as driver fatigue) is one of the main contributors to road accidents every day and approximately 30% of young drivers (16 to 24) are involved in fatigue-related crashes.
On average 31 people are killed and 462 seriously injured each year on Queensland roads as a result of crashes where fatigue played a part .
Did you know?
- Being awake for 17 hours poses the same risk of a crash as drivers with a BAC (blood alcohol concentration) reading of 0.05 g/100ml 
- 1 in 3 people have experienced micro sleeping behind the wheel
- Fatigue-related crashes are almost three times as likely to be fatal than crashes not involving fatigued - drivers who are asleep can't brake .
Tips to manage driver fatigue
When trying to manage fatigue while driving there is one main tip you should keep in mind; get enough sleep.
- Plan to take a break every 2 hours for up to 15 minutes at a time
- Don’t drive for more than 10 hours a day
