Following the example set by the Canadian Medical Association (CMA) guide on the evaluation of fitness to drive since publication of the 1st edition in 1974, nearly a half century ago, this 10th edition continues to provide current, practical information for health professionals who have determined that a patient has a condition that may affect their fitness to drive. In consideration of this orientation, clinical information on the diagnosis and evaluation of the various medical conditions has been kept to a minimum to allow the health professional rapid access to guidance on the effects of the given conditions on fitness to drive.

This edition incorporates the latest recommendations of the Canadian Cardiovascular Society (CCS), to be published in 2023. It also profits from the series of systematic literature reviews conducted under the auspices of the Monash University Accident Research Centre and published in the 3rd edition of its report entitled Influence of Chronic Illness on Crash Involvement of Motor Vehicle Drivers (Charlton et al., 2021) (often referred to as the “Monash Report”).

All sections in this guide have been revised by their respective authors, and references are provided within each section to enable the interested reader to further their knowledge as desired. It is also intended that the references will facilitate the justification for medical standards for fitness to drive if those standards are challenged, a situation that is increasingly frequent for licensing agencies.
