Health, road and environmental safety, service and logistics
Domain 3 tests fitness to drive, healthy routines, environmental awareness and the service and planning side of goods transport. The exam expects practical judgement: can you stay alert, protect vulnerable road users, meet customer promises and reduce empty running without breaking rules?
Health and alertness
Sleep is the only reliable cure for fatigue. Plan sleep before a shift, treat 4–5 hours as inadequate, and use a 15–20 minute nap only as a short-term measure. Eat light meals, drink water, and avoid heavy meals before night driving. Alcohol, cannabis, some cold medicines and antihistamines impair driving; check the label and Danish limits. Report medical conditions and eyesight changes. Noise, vibration and whole-body vibration in a cab add to fatigue.
Environment and Danish zones
Denmark's largest cities have environmental zones that restrict older diesel vehicles; check the vehicle's Euro class and particulate filter before routing into Copenhagen, Aarhus, Odense or Aalborg. Correct AdBlue/SCR operation, tyre pressure, load weight and smooth driving reduce NOx, particulates and CO2. Avoid unnecessary idling and noise in residential areas; night deliveries may have local time restrictions.
Service and logistics
Confirm delivery windows, access restrictions, pallet exchange and paperwork before departure. Use load space well: a trailer that runs 60% empty on the return leg costs more per pallet. Combine drops, backload where possible, and communicate delays early. Record damage and shortages with photos and a signed note; do not promise a resolution you cannot authorise.
Worked example
A driver starts at 06:00 with 3 h 40 min driving and 4 h 30 min of deliveries. A 45-minute break and a 20-minute delay are added. Finish = 06:00 + 3:40 + 0:45 + 4:30 + 0:20 = 15:15. A 15:00 delivery window cannot be met. The planner should move the last drop, warn the customer at once, or add a second driver; skipping the break is not an option.
Traps
Using coffee instead of sleep; ignoring an environmental-zone restriction; overpromising a window; and treating a backload as free capacity without checking axle loads.
