Driving-hours breach and tachograph mismatch on the Salalah run
You are assigned a Muscat–Salalah run of about 1,000 km. The tachograph chart and digital record show: 04:10 driving, 30 minutes break, 04:50 driving, 45 minutes break, then 03:20 driving. It is now 20:30 and you are at Haima, 430 km from Salalah. Company policy limits driving to 9 hours per day, extendable to 10 hours twice a week, requires a 45-minute break after no more than 4.5 hours of driving, and requires 11 hours of daily rest, reducible to 9 hours no more than three times a week. You have had two coffees since the last stop and feel alert. Dispatch calls and says the customer will reject the load if it is not there by 06:00. The vehicle is loaded with chilled food and the refrigeration unit is running normally.
1. Assess the driving and break record against the stated limits.

Driving totals 04:10 + 04:50 + 03:20 = 12 hours 20 minutes, which exceeds even the twice-weekly 10-hour extension. The first break was only 30 minutes after 4 hours 10 minutes; under the stated 45-minute rule it does not reset the 4.5-hour driving period, so the driver accumulated 9 hours of driving with only a 30-minute qualifying interruption before the later 45-minute break. That is a break violation as well as a daily driving-limit violation. The 45-minute break after the second block is valid, but it cannot undo the earlier breach. At 20:30 the driver has already exceeded the limit and cannot lawfully or safely complete the remaining 430 km. Alertness after coffee is not a substitute for rest, and the tachograph record must reflect the actual activity.
2. What should you do at Haima, and what should you tell dispatch?
Read the worked answer
Stop at Haima, park safely, and take the required daily rest before any further driving. Do not record the stop as a break or continue to Salalah to meet the 06:00 delivery. Inform dispatch clearly: the driving limit is already exceeded, the remaining 430 km would take roughly 5.5 to 6.5 hours at safe heavy-vehicle speeds plus breaks, and arriving by 06:00 cannot be done within the rules. Ask dispatch to notify the customer and arrange a later delivery slot or a relay driver who has not exhausted their hours. Record the actual rest period and any manual entries accurately. The chilled load is a commercial issue, not a reason to drive illegally; refrigeration can be monitored while the vehicle is stationary, and the operator should plan contingencies such as a relief driver at Haima.
3. How should the remaining journey be planned once rest is complete?
Read the worked answer
After a full daily rest, plan the 430 km as a fresh duty with realistic average speed. A loaded heavy vehicle may average 65–75 km/h on this road, so the drive itself is about 6 hours, plus at least one qualifying 45-minute break and any fuel or check stops. Confirm the driver has not used up weekly extensions, and check the tachograph for the new day before departure. Do not pre-set the arrival time from a light-vehicle estimate. The driver should start only when fit, carry out the walk-around check, confirm the refrigeration unit and load, and record the rest correctly. If the customer requires an early delivery, the operator should use a relay or reschedule rather than compress rest. The reasoning is that fatigue risk rises sharply at night and after a long day, even when the driver feels alert.
