Final answer:
When driving, adjust the seat and backrest to support your natural spine curve and ensure your feet can reach the pedals comfortably. Maintaining good posture and sitting up straight can help prevent back strain and fatigue. Make adjustments before driving and always use the seat belt.
Step-by-step explanation:
When driving, it is important to have your seat and back properly adjusted for comfort and safety. Start by adjusting the driver's seat so that your feet can easily reach the pedals and your knees are slightly bent. The backrest should be adjusted to support the natural curve of your spine.
Having the seat and back adjusted correctly can help prevent back strain and fatigue during long drives. It is also important to sit up straight and avoid slouching to maintain good posture and reduce the risk of injury.
Remember to make any necessary adjustments to the seat and backrest before starting the vehicle and always use the seat belt for added safety.
