Driver fatigue is one of the most underestimated causes of serious motor vehicle accidents in Alberta. Most people understand the dangers of impaired driving, but far fewer treat drowsy driving with the same level of concern. The reality is that a driver who has been awake for 18 hours or more shows similar impairment to someone over the legal alcohol limit. When that driver crosses into your lane, runs a red light, or rear-ends your vehicle, the consequences can be just as devastating.
At MNH Injury Lawyers, we help accident victims in Edmonton and across Alberta understand their rights after crashes caused by fatigued drivers. These cases can be more complex than they appear, and the evidence that matters most often disappears quickly.
Why Fatigued Driving Is More Dangerous Than Most People Realize
Fatigue affects a driver’s ability to react, make decisions, and stay in their lane. Unlike alcohol, there is no roadside test for drowsiness, which means fatigued drivers often go unchecked until something goes wrong.
Driver fatigue can result from a range of causes, including:
- Not getting enough sleep the night before
- Poor quality sleep caused by conditions like sleep apnea or insomnia
- Long shifts or back-to-back work without adequate breaks
- New medications or changes in dosage that cause drowsiness
- Underlying health conditions, including diabetes, anemia, or respiratory illness
- Prolonged stress that disrupts normal sleep patterns
One of the lesser-known risks is microsleep. This is a brief, involuntary lapse into sleep that lasts only a few seconds. A driver may not even realize it happened. At highway speed, a few seconds of microsleep means a vehicle travels well over a hundred feet with no one in control. The driver may wake up in oncoming traffic or having already struck another vehicle.
Truck Drivers and Fatigue in Alberta
Commercial truck drivers face particular pressure when it comes to fatigue. Long hauls, tight delivery schedules, and inconsistent rest stops all contribute to drowsiness behind the wheel of a vehicle that can weigh up to 40 times more than a standard car.
Federal regulations in Canada set hours-of-service limits for commercial drivers, but violations do occur. When a trucking company pushes drivers to meet unrealistic deadlines or ignores signs that a driver is fatigued, the company itself can share liability for any resulting accident.
If a commercial truck was involved in your accident, a lawyer can help identify whether the driver complied with federal rest requirements and whether the trucking company bears responsibility alongside the driver.
Rideshare Drivers and Fatigue
Uber and Lyft drivers in Edmonton often treat ridesharing as a second job on top of full-time work. Platforms like these allow drivers to work up to 12 to 14 consecutive hours before requiring a rest period. Many drivers push those limits, particularly during busy overnight hours.
Unlike commercial trucking, rideshare companies do not screen drivers for medical conditions that affect alertness, such as narcolepsy or sleep apnea. There is also limited oversight once a driver is on the road. If you were injured as a passenger or in a collision involving a rideshare vehicle, fatigue may have played a role even if it was not immediately identified at the scene.
How Fault Is Proven in a Fatigued Driver Case
Proving that a driver was fatigued at the time of a crash requires more than a statement from the other driver. In Alberta, establishing negligence means showing that the driver had a duty to drive safely, that they failed to meet that duty, and that their failure directly caused your injuries and losses.
Evidence that can support a fatigued driving claim includes:
- The driver’s logbooks or hours-of-service records (critical in commercial truck cases)
- Cell phone data showing activity in the hours before the crash
- Witness accounts describing erratic driving before the impact
- Dashcam or traffic camera footage
- Police reports noting the driver appeared drowsy or disoriented
- Employment records showing shift patterns or overtime
Speaking with a lawyer early after your accident can make a real difference. Some of this evidence has a short window before it is lost or overwritten, and an experienced car accident lawyer can act quickly to preserve it.
What Compensation May Be Available
If a fatigued driver caused your accident, you may be entitled to compensation that goes beyond what insurance initially offers. This can include:
- Medical expenses and future rehabilitation costs
- Income lost during recovery and any reduction in future earning ability
- Pain and suffering, including emotional trauma and PTSD
- Out-of-pocket costs related to your injury and recovery
Post-traumatic stress disorder is more common after serious car accidents than many people expect. Triggers like sounds, sudden movements, or even driving past a familiar intersection can affect daily life long after the physical injuries have healed. These are real, compensable losses under Alberta law, and they should be accounted for in any claim.

Frequently Asked Questions
How do I prove the driver who hit me was fatigued?
Direct proof can be hard to find, but a lawyer can gather supporting evidence such as the driver’s work schedule, logbooks, cell phone records, witness statements, and any dashcam footage from the scene. In commercial truck cases, federal hours-of-service records are particularly important.
Can I sue a trucking company if a tired truck driver caused my accident?
Yes, in many cases. If a trucking company required or encouraged a driver to exceed safe working hours or ignored known fatigue risks, the company can share liability for the resulting accident alongside the driver.
What if the fatigued driver was an Uber or Lyft driver?
Rideshare accidents involving fatigued drivers can involve multiple insurance layers. A lawyer can help identify which policy applies and whether the platform bears any responsibility based on the driver’s hours and working conditions at the time of the crash.
Is drowsy driving treated the same as impaired driving in Alberta?
There is no breath test for fatigue, so the legal process differs from impaired driving cases. However, a driver who chose to get behind the wheel while dangerously tired can still be found negligent and held liable for the harm they cause.
How long do I have to file a claim after a fatigued driving accident in Alberta?
In most cases, you have two years from the date of the accident to start a personal injury claim in Alberta. Acting sooner is important, both to preserve evidence and to make sure your options stay open.
