The risk of automobile accidents increases with parkinsonian disability, according to this study.  
 
Thirty-nine PD patients (including 17 who had reduced or stopped driving after disease onset) underwent driving tests in a driving simulator. Total collisions in the simulator were elevated approximately six-fold compared to age-matched controls (p<0.01), and remained significantly elevated even after removing non-driving PD patients from the analysis. Number of collisions was significantly correlated with UPDRS motor score and Hoehn and Yahr stage, but not with patient self-report of driving ability, or with presence of tremor or dyskinesia. While the present study did not test it, the authors noted that, anecdotally, physician assessment of driving-related ability is not correlated with driving ability as determined by the simulator.
