Road safety in drivers with Parkinson disease.

ABSTRACT:

Objective

To assess road safety and its predictors in drivers with Parkinson disease (PD).

Methods

Licensed, active drivers with PD (n = 84; age = 67.3 +/- 7.8, median Hoehn & Yahr stage II) and controls (n = 182; age = 67.6 +/- 7.5) underwent cognitive, visual, and motor tests, and drove a standardized route in urban and rural settings in an instrumented vehicle. Safety errors were judged and documented by a driving expert based on video data review.

Results

Drivers with PD committed more total safety errors compared to controls (41.6 +/- 14.6 vs 32.9 +/- 12.3, p < 0.0001); 77.4% of drivers with PD committed more errors than the median total error count of the controls (medians: PD = 39.5, controls = 31.0). Lane violations were the most common error category in both
