Fatigue-related road deaths and serious injuries are not restricted to rural and regional roads, nor are they restricted to people driving long distances.
You’re most at risk between 1am and 6am when your alertness is low.
Factors increasing your risk of being involved in a sleep-related vehicle crash include:
- working a night shift;
- averaging less than 7.5 hours sleep per night;
- poor overall quality of sleep;
- excessive daytime sleepiness;
- frequent night time driving (especially between midnight and 6am);
- use of medications that cause drowsiness;
- driving after being awake for more than 15 hours;
- driving for extended periods of time;
- air toxic emissions from new motor vehicle interiors
If you have a new vehicle, the CSIRO recommends that you make sure that there is plenty of outside air entering the vehicle while you drive for at least 6 months after purchasing the vehicle. The air toxic emissions from new motor vehicle interiors can cause fatigue.
