Correct answer
B. Position the driver's seat, adjust the mirrors and fasten the seat belts if the truck is equipped therewith.
Explanation
In the photo, you can see the inside of the cab: the driver's seat, the steering wheel and the dashboard - the workplace you prepare before driving. The order is: you adjust the seat, then the mirrors, and you fasten the seat belt if the vehicle is fitted with one - answer B.
The Road Traffic Act requires a vehicle to give the driver a sufficient field of view and easy, comfortable and reliable use of the steering and braking devices, and a person travelling in a vehicle fitted with seat belts has a duty to wear them. The order follows logic: first you adjust the seat, because its position determines what you see in the mirrors and whether you can reach the pedals; then you adjust the mirrors to your new body position; you fasten the seat belt at the end, when you are already sitting the way you will drive. A different order (answers A and C) ends with you having to correct everything after fastening the seat belt or after adjusting the mirrors. In a lorry, you also adjust the seat suspension to the driver's weight and check the setting of the additional mirrors.
