The Duty Day That Ran Long
You are a Class C driver on a charter. Your day began at 06:00 with a pre-trip. You drove 2 hours 15 minutes to a venue, waited 3 hours 30 minutes on duty but not driving, then drove 1 hour 45 minutes to a second stop. After a 45-minute meal break off duty, you drove 2 hours 10 minutes to a third stop and have been waiting 1 hour 50 minutes, on duty, since. It is now 18:20. The organizer asks you to run a 1 hour 40 minute return trip so the group is home by about 20:15. You have had about 6 hours of sleep and feel a mild headache. Your licence is a Class C with a Z endorsement and an air brake endorsement; the bus is a 46-passenger school-type vehicle with air brakes.
1. Work out your driving time so far, your on-duty time, and whether the requested return trip is permissible.
Read the worked answer
Driving so far: 2 h 15 + 1 h 45 + 2 h 10 = 6 h 10 min. On-duty time: driving 6 h 10 plus the 3 h 30 wait plus the current 1 h 50 wait = 11 h 30 min on duty, with the 45-minute meal break off duty. A 1 h 40 return trip would bring driving to 7 h 50 and on-duty time to about 13 h 10, and it would push the elapsed day past 14 hours. Whether that is permissible depends on the specific hours-of-service regime that applies - daily driving limits, on-duty limits, mandatory off-duty periods and any cycle limits - but even before checking those, the pattern is close to several limits at once and I would need to verify each one rather than assume. The safe answer is that I cannot simply accept the request; I must calculate against the applicable limits and, if the trip would breach them, decline or arrange relief.
2. Assess your fitness to drive, and what you would do about the headache and fatigue.

Six hours of sleep plus a long day with fragmented waiting is a fatigue risk, and a headache may be a symptom of dehydration, fatigue or something more. I would not treat the request as routine. I would take a proper break, eat and hydrate, and honestly assess whether I can sustain concentration for another 1 h 40 in evening traffic with a passenger load. If I am not confident, I do not drive - fatigue impairs reaction time and judgement in ways the driver cannot reliably self-detect, and a busload of passengers is not the place to test it. I would tell the organizer I cannot make the return trip, and arrange either relief, a second driver, or an alternative for the group. If the headache worsened or came with other symptoms, I would seek medical advice rather than drive.
3. A colleague offers to drive the return leg even though he has been off duty all day. What do you check before handing over?
Read the worked answer
I check that he holds the correct class of licence for the vehicle and the required endorsements - for this air-brake-equipped bus, the air brake endorsement, and the Z endorsement if the configuration requires it - and that his licence is valid and not suspended. I confirm he is fit and not impaired, has had adequate rest, and has not already accumulated hours that would put him over the applicable limits. I brief him on the vehicle: any defects noted during the day, the air brake behaviour, the passenger count and any passengers needing assistance. I record the driver change and the time. Handing over does not transfer my responsibility to have verified these things, and if I cannot verify them, the trip does not run with him driving.
