Introduction: Impaired driving is the leading cause of criminal death in Canada and results in numerous emergency department (ED) visits each year. Methods: An online survey was distributed to 94 emergency physicians and emergency medicine residents at an academic tertiary care hospital in Southwestern Ontario. Descriptive statistics were calculated. Results: We received 76 responses (81% response rate). Physicians widely varied in the frequency with which they discussed the dangers of drinking and driving with patients. Only 13% had consulted the ED social worker and 32% had used an alcohol screening questionnaire in the past 12 months. The greatest barriers to addressing drinking and driving with motor vehicle collision (MVC) patients were severity of injury, lack of time and intoxication. The great motivators were a sense of personal responsibility, concern for patients' health and safety and having the time. Conclusion: The information from this survey brings awareness to the longstanding problem of drinking and driving, explores the barriers and motivators to addressing this topic in the ED, and can be used to develop new strategies to educate trauma patients on the dangers of impaired driving.
