Fatigued Drivers - A High Risk On Roads

‘The Weekly Advertiser’ Horsham and Wimmera District. EDITORIAL by Lauren Henry

Anyone who has driven back home to the Wimmera and Grampians regions from Melbourne (298kms), particularly after a busy weekend, knows all too well how fatigue can set in.

Driving along the Western Highway, or any country road, for a lengthy period can be a challenge at any time of day, but even more so if the driver has not had enough sleep.

A list of pre-arranged engagements has meant I have spent about every weekend for the past six weeks clocking up thousands of kilometres.

It is tiring, it is laborious, and at times, boring.

Research shows drivers are four times more likely to crash if they have had less than five hours’ sleep. Tired drivers contribute to about 20 percent of fatal crashes on Victorian roads each year.

Crashes caused by fatigue accounts for about 25 percent of road trauma injuries at The Alfred and Royal Melbourne hospitals.

It does not seem difficult to prevent fatigue – it is simple to pull over and have a nap. 

Let us not only care about our own safety and those of loved ones, but the impact that driving while fatigued can have on all the other road users.

DROWSINESS & FATIGUE RISK QUICK FACTS

NATIONAL ROAD SAFETY PARTNERSHIP PROGRAM (NRSPP)

Why is it a problem?

When we are fatigued or drowsy:

  • Alertness is reduced.
  • Less able to detect things going wrong with our driving.
  • Less able to work out what needs to be done.
  • In extreme cases, we may fall asleep at the wheel with total loss of awareness and control.

What causes it?

  • Not enough sleep.
  • Broken or poor-quality sleep.
  • Disruption of the daily routine, e.g. driving when you would normally be asleep.
  • Sustained concentration or physical effort, long hours a work.
  • Not just a work problem.
  • Stresses from the environment, such as heat, noise, vibration, bright light.
  • Medical conditions such as sleep disorders, diabetes or serious pain may contribute to fatigue.

Fatigue related crashes are four times more likely between 10pm & dawn.

What risks does insufficient sleep pose?

After 17 hours awake, the decrement in driving performance is equivalent to a BAC of 0.05

After 21 hours awake, the decrement in driving performance is equivalent to a BAC of 0.15
