Position your seat so you can reach the pedals comfortably with slightly bent knees and a fully supported back.
Ensure the seat height allows a clear view of the road and dashboard, with hips level with or slightly above knees.
Ensure adequate lower back support. Use a cushion or rolled-up towel if needed.
Sit upright with your back fully against the seat, maintaining the natural curve of your spine.
Align the headrest top with the top of your head to support your neck and prevent whiplash.
Ensure the steering wheel is close enough for a comfortable grip with slightly bent arms.
On long drives, take regular breaks to stretch and walk around to prevent stiffness and discomfort.
