• Driving when tired is a contributing factor in between 16-20% of all road crashes in Victoria.
• Young drivers are more likely to be involved in fatigue related crashes.
• We are most tired between midnight and 6am, with tiredness peaking between 3am and 5am. There is also an afternoon dip in alertness.
• Any driver can suffer tiredness, even on short trips.

The aim of the impaired driving assessment (track trial) was to determine the risk of a crash following varying levels of sleep loss under controlled conditions. Volunteers participated in a 2 hour drive (on a closed track) in a dual-controlled vehicle accompanied by a qualified and experienced driving instructor. These drives took place after 4 sleep conditions:

• Well rested (8 hours sleep)
• 5 hours sleep within 24 hours
• 3 hours sleep with 24 hours
• Total sleep deprivation (zero sleep)

The research found the risk of crashing after 5 hours of sleep was 4.4 times compared to 8 hours of sleep. Under 5 hours sleep the crash risk increased substantially.

Before you drive, make sure you:

• Get a good night’s sleep - ideally at least seven hours of good, undisturbed sleep.
• Avoid driving at times you’re normally sleeping.
• Understand the effects any medicine you're taking might have on your driving.
• Take regular breaks – at least every two hours.
• Know and look for the warning signs of fatigue.
• When possible, arrange to share the driving.
• When you know you’re fatigued, avoid driving altogether. Take a taxi, public transport or rely on another driver.

If you are driving:

• Seek somewhere to stop and rest when feeling any signs of sleepiness.
• Pull over in a safe place (such as a rest area, tourist spots, Pause Stop or Driver Reviver site) and take a break or have a 15 minute powernap.
• When possible, share the driving.

Watch for the warning signs

• Difficulty keeping to the centre of the road.
• Struggling to keep your eyes open.
• Blurred vision/ eyes losing focus.
• Zoning out, loss of concentration or mind wandering.
• Nodding off to sleep, head nodding, or jerking back up (if this happens, stop driving).
• Not being able to recall the previous few minutes of driving (being on ‘auto-pilot’).
• Feeling bored, irritable, aggressive or impatient.

Our Pause Stop sites are running across Victoria during key holiday periods. The stops are to encourage drivers to pull over, recharge so you can get to your destination safely.

There are more than 60 places to pause from the road across Victoria during key holiday periods.

What is the source of the statistic?

The campaign was informed by two pieces of research from Monash University.

1. The impaired driving assessment – Track Trial: The main findings from the research found the risk of crashing after 5 hours of sleep was 4.4 times compared to 8 hours of sleep. Under 5 hours sleep the crash risk increased substantially.
2. Attitudes and Awareness Towards Drowsy Driving Survey: The main findings from the survey found;

• Young males reported a greater risk of falling asleep behind the wheel.
• Good awareness among the population of the dangers of driving tried.
• Minimum sleep requirements were the largest risk factor when driving tried.

Are there any proven benefits to stopping to powernap?

What are some suggestions on how I can avoid driving if I am tired?

• Avoid driving at times you would normally be sleeping
• Plan your drive, drive when well rested
• Have a powernap (15 -20 minutes)
• When possible, arrange to share the driving
• Take a taxi, public transport or rely on another driver

What am I supposed to do if I live in a rural area?

If you live in a rural area where taxi’s or public transport are not available, consider relying on another driver, or avoid driving altogether. Aim to get at least seven hours of good, undisturbed sleep before driving

Are there any support services for those who are concerned about their sleep quality?

The Sleep Foundation or speak to your GP

How can I drive in a safer way if I’m tired and driving is unavoidable?

Try to avoid driving when you would usually be sleeping. An especially dangerous time is between midnight and 6am, with tiredness peaking between 3am and 5am.
