Examination of naturalistic driving practices in drivers with Parkinson's disease compared to age and gender-matched controls

► Drivers with PD appear to restrict their driving practices (i.e., drive less km overall, at night and in bad weather). ► Drivers with PD drove faster on highways/freeways than controls and may have impaired speed control. ► Drivers with PD had lower perceptions and perceived driving abilities than controls. ► Objective driving measures are needed to capture real driving behavior/practices.
