Driver fatigue is a term often associated with those spending long hours behind the wheel, such as drivers in the freight industry and those undertaking long road trips, whether for leisure or work. But driving a vehicle while impacted by sleep loss is a much wider issue in the community, including over short distances.

The Sleep Health Foundation estimates that more than half of Australian adults are suffering from at least one chronic sleep symptom. And almost half (48%) of all Australian adults report at least two sleep-related problems according to the Australian Institute of Health and Welfare.

It follows that the number of drivers on our roads who are operating a vehicle while affected by sleep loss must also be high.

This episode unpacks the impacts of poor quality and inadequate sleep on driving, and practical steps you can take to prevent driving tired.
