Abstract: Few studies have presented three-dimensional car-driving postural information. This laboratory study investigated drivers| preferred postures, preferred interior dimensions and how they characterise their postures. The minimum-maximum intervals of preferred angles corresponded well with other experimental studies and were larger than intervals for comfort, strength and alertness defined on the basis of theoretical reasoning. No preferred posture differences were found between females and males; nor were differences found when comparing posture after five and twenty minutes of driving. Preferred posture was not symmetric: significant differences were found between the left and right side. Subjects characterised their posture as comfortable, relaxing and restful.

Keywords: vehicle design; cockpit design; driver posture; human simulation; joint angles; cabin comfort; driver comfort; 3D modelling.
