Age-related medical conditions such as Parkinson's disease (PD) compromise driver
fitness. Results from studies are unclear on the specific driving errors that
underlie passing or failing an on-road assessment. In this study, we determined
the between-group differences and quantified the on-road driving errors that
predicted pass or fail on-road outcomes in 101 drivers with PD (mean age = 69.38
+/- 7.43) and 138 healthy control (HC) drivers
(mean age = 71.76 +/- 5.08).
Participants with PD had minor differences in demographics and driving habits and
history but made more and different driving errors than HC participants. Drivers
with PD failed the on-road test to a greater extent than HC drivers (41% vs. 9%),
chi(2)(1) = 35.54, HC N = 138, PD N = 99, p < .001. The driving errors predicting
on-road pass or fail outcomes (95% confidence interval, Nagelkerke R(2) =.771)
were made in visual scanning, signaling, vehicle positioning, speeding (mainly
underspeeding, t(61) = 7.004, p < .001, and total errors. Although it is
difficult to predict on-road outcomes, this study provides a foundation for doing
so.
