This Parkinsons Report is fantastic. Here is some more information I thought may help people.
In a journal article by Charles M. Posner M.D. of Harvard Medical School published in 1993, the author reviewed the regulations of The Department of Motor Vechiles of all 50 states with regard to neurologically impaired drivers and applicats for licensure. There was, of course a great variation on the approach and requirements of several jursidictions.
The following is a direct quote from Dr. Posner's comments with regard to PD:
"Parkinsonism deserves special attention.Although many persons with that condition do not manifest sufficent motor weakness to warrant limiting their driving, slowness of movement (bradykinesia) and rigidity greatly prolong reaction times. As a result they are unable to respond quickly to changing conditions. On that basis driving should be forbidden until they can demonstrate improvement on mediciation. The most accurate assessment is one not made by a physician, but by an experienced driving examiner who conducts a road test under normal traffic conditions. Simulator tests are more realistic for patient testing. In Hoehn and Yahr's stage 1 of parkinsons diease computer simulators tests show that the accuracy of of steering, reaction time,and interperation of traffic signals are impaired. The timing of any assesment of driving in PD may be crucial in relation to diease variability and the on and off phenomenon.
Sorry this is so long but I thought it was worth talking about
