This article discussed the content and development of the University of Western Ontario’s on-road course. Components for developing an on-road course were identified and face, content, and initial construct validity were assessed using measurement theory. Based on the results of 35 participants, including 30 drivers with multiple sclerosis (MS) and five adult driver volunteers, the road course had face and content validity. Findings show that drivers with MS vs. control drivers had more driving errors and failed the on-road course, thus indicating the construct validity of the assessment. The use of a systematic process provided content guidelines and empirical support for health professionals developing a road course and on-road assessment.
