The current study was designed to confirm that female drivers sit closer to the steering wheel than do male drivers and to investigate whether this expected dif- ference in sitting position is attributable to differences in the physical dimensions of men and women. Driver body dimensions and multiple measures of sitting dis- tance from the steering wheel were collected from a sample of 150 men and 150 women. The results confirmed that on average, women sit closer to the steering wheel than men do and that this difference is accounted for by variations in body dimensions, especially height. This result suggests that driver height may provide a good surrogate for sitting distance from the steering wheel when investigating the role of driver position in real-world crash outcomes. The potential applica- tions of this research include change to vehicle design that allows independent adjustment of the relative distance among the driver's seat, the steering wheel, and the floor pedals.
