Learn how fatigue affects your driving, the warning signs to watch for, and what to do when tiredness starts affecting your concentration behind the wheel.
Being Awake Doesn't Mean You're Alert
You can push through tiredness at work. You can push through it while studying. But when you’re behind the wheel, pushing through tiredness is like inviting trouble. Because fatigue behind the wheel isn’t obvious. It’s visible in subtle signs like a missed traffic sign, a slower reaction at an intersection, or drifting slightly within your lane. Before you realise what’s happening, you find yourself microsleeping behind the wheel with only a vague idea of the last few minutes of the journey. That’s why Sydney driving school instructors focus so much on teaching drivers to always stay alert behind the wheel and avoid driving while tired. The NSW Government considers fatigue to be as dangerous as drink driving. Research shows that being awake for around 17 hours can have a similar effect on driving performance as a blood alcohol concentration of 0.05. That’s why understanding fatigue early is just as important as learning how to steer, brake, and change lanes.
Why Fatigue Changes the Way You Drive
When you’re tired, your concentration is low, judgment suffers, and reaction time is slower. While it may not be a big deal in some other circumstances, these things matter a lot when you’re driving. For example, when you’re approaching an intersection, responding to a sudden change in traffic, or trying to maintain a safe position on the road, being quick, decisive, and alert is essential.
Whether it’s a short trip or a long journey, fatigue increases the risk of an accident. And unlike what you might believe, familiarity doesn't remove that risk. You might feel capable of driving home after a long day because you've travelled the route many times before. However, even a few seconds of microsleep or losing focus for a few moments, and you’ve travelled many meters without being alert. A microsleep is a brief, unintended episode of sleep. Even a few seconds of microsleep behind the wheel can be dangerous. For example, you’re driving at 100 km/h. Here, even a four-second microsleep can mean travelling more than 110 metres without your eyes on the road. During this time, you might encounter a pedestrian, hit an animal, miss a sign, or run a light.
That’s why drivers must remember that fatigue isn't an isolated driving risk. It's one of the Fatal 5 road safety risks, alongside behaviours such as distraction, speeding, and driving under the influence. Understanding these risks together can help you recognise how everyday decisions can affect your safety on the road.
Don't Wait Until You Can Barely Keep Your Eyes Open
So, how do you recognise how tired you are? You might think that when you start feeling sleepy or microsleeping, that’s the first indication of fatigue. However, that’s not true. Fatigue often gives you warning signs before a microsleep occurs. Watch for:
-
Frequent yawning or drowsiness
-
Tired or sore eyes
-
Difficulty concentrating
-
Slower reactions
-
Missing road signs
-
Feeling restless or irritable
-
Making larger steering corrections
-
Having difficulty staying in your lane
If you notice these signs, don't try to push through because you're close to your destination. Pull over somewhere safe and take a break.
What Should You Do If You Feel Tired?
Sleep is the best way to reduce fatigue. Even the NSW government recommends getting at least eight hours of sleep and planning regular breaks before a journey. So, if you’re driving and start feeling tired, pull over somewhere safe and have a quick nap. And if you’re travelling with other passengers who can drive, you can share the driving too, provided the other driver is rested and fit to drive. If you're on a short trip, a coffee may temporarily increase alertness, but caffeine doesn't work for everyone and isn't a substitute for sleep. When you’re genuinely very tired, don't rely on caffeine to get you through a longer journey.
