DDAD/SIDA (Drowsy Driving Awareness Day/ Sleep Impaired Driving Awareness)
OVERVIEW
Drowsy Driving Awareness Day – Sleep: There Is No Substitute forms part of Canada’s Sleep Calendar, a coordinated programme of national public education presented by The Sleep Society to improve sleep health awareness across Canada.
Sleep-impaired driving remains an under-recognised risk on Canadian roads. Importantly, a driver does not have to fall asleep at the wheel to become unsafe. Insufficient sleep, prolonged wakefulness, circadian disruption and untreated sleep disorders can reduce alertness, slow reaction time and impair concentration, judgement and decision-making before a driver fully recognises the danger.
Drowsy Driving Awareness Day aims to broaden the conversation beyond simply “feeling tired.” By encouraging Canadians to recognise sleep impairment as an important road-safety issue in its own right, the initiative promotes a simple message: Sleep is not a luxury—when we drive, there is no substitute for being sufficiently rested.
WHY IT MATTERS
Driving is a complex activity requiring sustained attention, rapid reactions, sound judgement and continuous decision-making. Sleep loss and fatigue can compromise each of these abilities, while microsleeps—brief, involuntary episodes of sleep—can occur when a severely sleepy person is attempting to remain awake.
One of the greatest challenges is that people may underestimate their own impairment. A driver may recognise alcohol or drug impairment before driving, yet still begin a journey after inadequate sleep or continue driving as alertness progressively deteriorates.
The problem affects people from all walks of life, including shift workers, commercial drivers, healthcare professionals, students, parents and anyone experiencing insufficient or poor-quality sleep. Sleep disorders including obstructive sleep apnea and narcolepsy may also increase driving risk when inadequately recognised or treated.
BACKGROUND
Drowsy Driving Awareness Day is observed in September as part of Canada’s Sleep Calendar and promotes greater recognition of sleep impairment as an important and preventable road-safety issue.
The dangers of alcohol-impaired, drug-impaired and distracted driving are now widely recognised. Sleep impairment has historically received considerably less public attention, despite the potentially serious consequences of driving without sufficient alertness.
The term “drowsy driving” is widely understood, but the problem extends beyond the moment when a driver actually feels sleepy. Inadequate sleep, prolonged wakefulness, circadian disruption, shift work and untreated sleep disorders can affect driving ability before the seriousness of the impairment is appreciated.
From 2026, Drowsy Driving Awareness Day became a proposed national initiative intended to support and bring together sleep-impaired and drowsy-driving awareness and prevention efforts across Canada. In British Columbia, The Sleep Society continues to advocate for greater recognition of sleep-related impairment within road-safety education and prevention.

CURRENT ACTIVITIES
The Sleep Society and SleepSafeCanada are currently working to:
- Promote greater public recognition of sleep-impaired and drowsy driving as important road-safety issues.
- Increase understanding that driving ability may be impaired before a person actually falls asleep at the wheel.
- Educate drivers about the effects of insufficient sleep, circadian disruption, fatigue and untreated sleep disorders on driving performance.
- Encourage drivers to recognise warning signs of increasing sleepiness and avoid or stop driving when they are not sufficiently alert.
- Develop educational resources for the public, healthcare professionals, employers, commercial drivers, transportation organisations and road-safety organisations.
- Support annual Drowsy Driving Awareness Day activities as part of Canada’s Sleep Calendar.
- Encourage collaboration with governments, automobile insurers, transportation authorities, law enforcement, healthcare organisations, employers and road-safety organisations.
- Continue dialogue in British Columbia regarding greater recognition of sleep impairment within road-safety education and prevention.
- Build partnerships and national support to expand sleep-impaired-driving awareness and prevention across Canada.
