Driver Safety
Beat fatigue on the long drive.
There's no trick that beats being tired at the wheel. Not coffee, not the window down, not the music up. Here's how to plan a long drive so you never find out the hard way.
The short version
Sleep is the only real fix. Break every 2 hours, and never push through the night to save time.
Quick read Everything you need before you set off

Spot the warning signs
A long drive lulls you. The road runs straight, the cabin is warm, and tiredness creeps in so quietly you don't notice until you've drifted. Your body warns you long before you fall asleep, but the signs are easy to explain away when you just want to get home. Treat any of them as a hard stop, not a suggestion.
Constant yawning
Your body asking for sleep, plainly.
Heavy, stinging eyes
Blinking hard or struggling to focus.
Slow reactions
You notice hazards later than you should.
Drifting in the lane
Wandering, or catching the rumble strip.
Zoning out
You can't recall the last few kilometres.
Restlessness
Fidgeting and shifting just to stay awake.
17hours awake
...affects you like a 0.05 blood alcohol reading.
Push it to 24 hours without sleep and you're driving as if you were twice the legal limit for a full licence. Tiredness isn't a mood, it's impairment, and the only thing that fixes it is rest.

When fatigue hits hardest
Tiredness isn't random. It follows your body clock, so some hours are far riskier than others. Where you can, plan the long stretches around them.
1am – 6amWhen your body most wants to be asleep. The riskiest window of all.
2pm – 4pmThe afternoon dip, even after a good night's sleep.
15 – 17 hrs upOnce you've been awake that long, your reaction time is already suffering.
After workThe end of a long day, before you've even started driving.
Plan the drive
Most fatigue crashes trace back to a trip that was in trouble before it began: too little sleep, too far in one go, no breaks built in. Sort the plan first and the drive largely looks after itself.
Before you go
- Get a proper night's sleep, 7 to 8 hours, the night before.
- Don't start a long trip straight after a full day's work.
- Plan the route and decide where you'll stop before you leave.
- Check the weather, and share the driving if someone can help.
On the road
- Take a break at least every 2 hours, sooner if you feel it.
- Swap drivers regularly if you've got a second licensed driver.
- Drink water, keep meals light, and skip the energy drinks.
- The moment a warning sign shows up, pull over. Don't push on.
Rest stops
- Use a marked rest area or a town, never the shoulder.
- Get out and move, a short walk resets you more than you'd think.
- Flagging badly? A 15 to 20 minute power nap in a safe spot.
- Caffeine can give false confidence and does not replace sleep. If you feel tired, stop in a safe place and rest or arrange another way to travel. Queensland fatigue guidance

Common questions
Does coffee sober up a tired driver?
Caffeine can give false confidence and does not replace sleep. If you feel tired, stop in a safe place and rest or arrange another way to travel. Queensland fatigue guidance
How long should a rest break be?
At least 15 minutes, and 30 to 60 is better on a long trip. Get out of the car, move around, and have some water. If you're genuinely drowsy, a 15 to 20 minute power nap in a safe rest area does far more than pushing on.
How far can I safely drive in a day?
As a rule of thumb, no more than 8 to 10 hours of actual driving, with a break at least every 2 hours. If your trip needs more than that, split it across two days rather than driving into the night.
Is a roadside power nap actually safe?
Yes, in the right place. Use a marked rest area or a quiet town street, lock the doors, set an alarm for 15 to 20 minutes, and expect to feel groggy for a few minutes when you wake. That short nap can be the difference on a long drive.
This is general information to help you plan a safe trip, not medical or legal advice. If you regularly feel tired at the wheel despite enough sleep, it's worth seeing your GP.
