Vehicle knowledge, load and passenger safety for class D1
What this domain tests
This domain covers the D1 vehicle itself, pre-trip checks, weight limits, load securing and passenger safety. In Norway, class D1 is a passenger vehicle with more than 8 and no more than 16 passenger seats in addition to the driver's seat, and a maximum length of 8 m.
Core rules
- Daily check: tyres and tread, lights, brakes, steering, mirrors, doors, emergency exits, seat belts, fire extinguisher, first-aid kit and warning triangle.
- Know the vehicle's maximum permitted total weight, axle loads, roof load and payload. Passengers and luggage count as payload; the Norwegian planning norm is 75 kg per passenger unless the vehicle documents state otherwise.
- Secure all luggage so it cannot move, block the aisle, cover emergency exits or strike passengers under braking.
- Passengers must use seats and seat belts where fitted. Do not carry standing passengers unless the vehicle is approved for it.
- Use correct child restraints and follow the seat-belt rules for children.
- Distribute load evenly and check that the rear overhang and doors remain safe.
Worked example
A D1 bus has a maximum payload of 1,500 kg. You carry 16 passengers at 75 kg = 1,200 kg. That leaves 300 kg for luggage, driver's belongings and any equipment. If the group has 400 kg of suitcases, you are overloaded even though every seat is legal. You must reduce luggage, use a trailer if approved, or split the group.
Traps that cost marks
Adding passengers but forgetting luggage; assuming roof load is unlimited; leaving a bag in the aisle; and relying on the number of seats alone instead of the vehicle's weight plate.
