The Late-Night Drive Home
It is 1:30 am. You have been awake since 6:00 am and have worked a full day plus a social event. You are driving home on a familiar road, about 20 minutes from home. You notice you have yawned several times, your eyes feel heavy, and you cannot recall the last few kilometres clearly. The road is quiet, the limit is 80 km/h, and there is a rest area 3 kilometres ahead. Your phone is in a cradle and a friend has just sent a message.
1. What do your symptoms indicate, and what should you do?
Read the worked answer
The symptoms indicate driver fatigue, which is a serious impairment.
Reasoning:
- Repeated yawning, heavy eyes, and poor recall of the last few kilometres are classic warning signs of fatigue. Fatigue slows reaction time and can cause micro-sleeps.
- You have been awake for roughly 19.5 hours, which substantially increases impairment comparable to being over the legal alcohol limit in terms of crash risk.
- Correct action: pull into the rest area 3 kilometres ahead and stop. A short nap of about 15 to 20 minutes, or ending the trip, is the safe response. Do not try to push through.
- Opening a window or turning up the radio does not cure fatigue and is not a substitute for rest.
2. Should you read or reply to the message now? Explain with reference to your legal responsibilities.
Read the worked answer
No. You should not interact with the phone while driving.
Reasoning:
- Using a hand-held mobile phone while driving is illegal, and even hands-free interaction is a distraction. Touching or looking at the phone in a cradle can still breach the rules depending on how it is used.
- Your fatigue already reduces your attention. Adding a phone task multiplies the risk.
- The message can wait. Deal with it after you have stopped safely at the rest area.
- If you need navigation, set it before moving off, and do not adjust it while the vehicle is in motion.
3. If you stop at the rest area, what should you check before resuming the drive?

Before resuming, confirm that you are fit to continue.
Checklist:
- Are you still experiencing yawning, heavy eyes, or difficulty concentrating? If so, do not drive; arrange another way home or sleep longer.
- Have you had a proper rest, not just a brief pause?
- Is the vehicle safe to continue: lights working, no warning signs, tyres and load secure?
- Is your phone set up for hands-free use only, with any messages left until you are stopped?
- Plan the remaining route and any further rest stops. If fatigue returns, stop again. The goal is to arrive, not to arrive quickly.
