Driver Fatigue: A Proven Risk on Canada’s Roads

Written By Andrew Holmes RPSGT, Corporate Sleep Consultant

How many people actually get the recommended amount of sleep each night?
For drivers—especially those in safety-sensitive roles—the answer to that question can mean the difference between a routine shift and a serious incident.

Driver fatigue isn’t theoretical. It’s a well-documented, ongoing safety issue across Canada’s transportation systems, and its impact extends well beyond individual drivers.

Fatigue Is a Recognized Safety Risk Across Transportation Sectors

According to Transport Canada and the Transportation Safety Board of Canada (TSB), sleep-related fatigue has been identified as a contributing factor or safety risk in at least 91 transportation occurrences since 2016. These incidents span multiple sectors:

  • 34 in aviation

  • 28 in marine

  • 29 in rail

While the TSB does not investigate motor vehicle crashes, international data consistently shows that fatigue is a factor in approximately 15–20% of road crashes. This places fatigue among the most significant—and most preventable—safety risks facing drivers today.

Fatigue and Commercial Vehicle Crashes in Canada

National Collision Database (NCDB) reporting shows that 4.8% of fatal commercial motor vehicle (CMV) crashes involved fatigue and alcohol as key contributing factors.

More broadly, collision data from 2016–2020 highlights two dominant contributors to fatal heavy vehicle crashes in Canada:

  • Inattention, which includes fatigue and distraction

  • High-risk driving behaviours, such as excessive speed

Fatigue directly contributes to both. A fatigued driver is more likely to miss hazards, experience lapses in attention, and make slower or riskier decisions—often without realizing how impaired they are.

Canada’s Current Approach to Managing Fatigue

Canada’s primary method for addressing driver fatigue is through Hours of Service (HOS) regulations, which limit how long a driver can work or drive before resting.

Key federal requirements include:

  • A maximum of 13 hours of driving time per day

  • A maximum of 14 hours of on-duty time per day

  • A mandatory 8 consecutive hours of off-duty time

  • No more than 16 hours elapsed between qualifying off-duty periods

These rules are essential and play a critical role in reducing extreme overwork. However, they are designed to manage time, not sleep quality or alertness.

Why Compliance Alone Isn’t Enough

Being off-duty does not guarantee restorative sleep. Drivers may fully comply with HOS regulations and still experience significant fatigue due to:

  • Poor sleep quality

  • Circadian disruption from shift work or overnight driving

  • Chronic sleep restriction

  • Undiagnosed sleep disorders such as obstructive sleep apnea

In these cases, fatigue persists even when regulations are followed—creating hidden risk for drivers, employers, and the public.

The Missing Piece: Proactive Fatigue and Sleep Management

Effective fatigue management requires moving beyond compliance toward a health-based, preventative approach that focuses on alertness, not just hours logged.

A comprehensive solution includes:

  • Fatigue and sleep education so drivers understand risk and early warning signs

  • Screening for sleep-related conditions in safety-sensitive roles

  • Access to diagnostic testing, including home-based sleep testing where appropriate

  • Clinical support and treatment pathways for drivers identified as high risk

This approach aligns with modern Fatigue Risk Management Systems (FRMS), which emphasize risk reduction through education, monitoring, and early intervention.

A Smarter Way Forward for Drivers and Organizations

Addressing driver fatigue effectively means treating sleep as a core safety issue—not just a personal responsibility.

Organizations that integrate sleep health into their safety and wellness strategies benefit from:

  • Reduced fatigue-related incidents

  • Improved driver alertness and performance

  • Lower absenteeism and turnover

  • Stronger safety culture and regulatory alignment

For drivers, it means better health, improved quality of life, and safer roads for everyone.

The Bottom Line

Driver fatigue is a measurable, preventable risk across Canada’s transportation systems. While Hours of Service regulations are necessary, they are not sufficient on their own.

The most effective solution combines regulatory compliance with proactive sleep health management—ensuring that drivers are not only rested on paper, but alert in practice.

When sleep becomes part of the safety conversation, everyone benefits.
