Night Trunk Run After Short Sleep
You are driving a 12-tonne rigid truck on the night trunk from Kuwait City to Abdali, then back to Jahra. You reported at 22:30 after about four hours' sleep. By 03:10 you have driven 5 hours 40 minutes with one 20-minute break. The company fatigue policy sets a maximum of 9 hours' driving per shift and requires a 45-minute break after 4 hours 30 minutes of driving. You still have 140 km to run, the delivery is due at 05:00, and the dispatcher has already called twice asking for an ETA. In the last 20 minutes you have yawned repeatedly, drifted onto the rumble strip once, and missed your intended exit. Your eyes feel heavy. The road is a straight dual carriageway with light traffic and no lighting for the next 30 km. You have a sleeper cab and a mobile phone.
1. Assess your fitness to continue using the symptoms and the policy, and state what you must do in the next few minutes.

The symptoms point to serious fatigue, not ordinary tiredness. Yawning repeatedly, heavy eyelids, drifting onto the rumble strip and missing an exit are warning signs of reduced attention and possible microsleeps. A microsleep at 80 km/h can cover more than 20 metres per second with no control input. The policy position is also breached: you have driven 5 hours 40 minutes with only a 20-minute break, while the policy requires 45 minutes after 4 hours 30 minutes. Your next action is to stop at the first safe place, such as a service area or a well-lit lay-by, not on the hard shoulder unless it is an emergency. Notify the dispatcher immediately that you are not fit to continue. Do not try to 'push through' the last 140 km; a 20-minute coffee stop is not enough to reverse sleep deprivation.
2. The dispatcher says the customer will reject the load if it is late and asks you to continue. How should you respond, and what alternatives should you propose?

Respond calmly but firmly: continuing would be unsafe and would also breach the company fatigue policy. Do not argue about fault or make personal accusations. State the facts: 5 hours 40 minutes driven, only one 20-minute break, missed exit, rumble-strip drift. Propose options: take a 45-minute break and then reassess, take a longer sleep in the sleeper cab before completing the run, arrange a relief driver at the next depot, or ask the dispatcher to call the customer and rebook the delivery window. If the load is time-critical, the dispatcher should arrange another vehicle rather than rely on a fatigued driver. Record the notification and the dispatcher's instruction. If the dispatcher insists you continue, escalate to the transport manager or safety officer; the driver remains responsible for not driving while unfit.
3. What should you record and change in your plan to reduce fatigue on the next night run?
Read the worked answer
Record the actual start time, sleep obtained, driving time, break times, symptoms, location of the stop and all communications with the dispatcher. For the next run, change the plan rather than merely repeat it. Aim for at least seven hours of sleep before a night shift, avoid starting a shift after a long day awake, and schedule the 45-minute break before the 4-hour 30-minute mark rather than after it. Plan the route around known rest areas, carry water and light food, avoid heavy meals immediately before driving, and do not rely on energy drinks to mask sleepiness. Where possible, avoid back-to-back night runs. If the same route and schedule keep producing fatigue, raise it as a scheduling problem, not a driver-discipline problem.
