In what order should you perform activities preparing you to drive the truck?

Explanation
Correct answer: Position the driver's seat, adjust the mirrors and fasten the seat belts if the truck is equipped therewith.
The correct sequence for preparing to drive is crucial for safety and comfort. First, adjust the seat to ensure an optimal driving position and proper access to the pedals. Only after assuming the correct position can the mirrors be adjusted properly, as their setting is dependent on the driver's position. Fastening the seat belts is the final step, performed immediately before starting to drive.
