Modes of Transportation – In an Automobile
Fatigue is one of the leading causes of traffic accidents on Québec roads, along with alcohol, speeding and distraction. Don't let fatigue take you to your final resting place. Stop as soon as you feel the first signs of fatigue.
Driver fatigue: numbers to think about
Each year on average, 78 people are killed and 8,532 people are injured in an accident related to driver fatigue.
From 2014 to 2018, fatigue was a factor:
- in 21% of fatal accidents
- in 23% of accidents that resulted in injury or death
Drivers most at risk
- Heavy vehicle drivers
- Drivers under age 30 and new drivers
- Workers who have irregular schedules or long work days
- Workers who work night shifts
- Individuals who suffer from an undiagnosed or untreated sleep disorder
- Individuals whose lifestyle affects the amount and quality of sleep they get
Recognizing the signs of fatigue
- You yawn often
- Your eyes are burning
- You have trouble keeping your eyes open
- You have trouble:
- finding a comfortable position, e.g. shifting around in your seat
- concentrating and staying attentive, e.g. missing an exit
- maintaining a steady speed and keeping the vehicle on a straight course
- Your reactions are slower
- You have memory lapses, e.g. you can’t remember the last few kilometres driven
- You are seeing things that are not there, particularly when there is fog or on monotonous stretches of highway, e.g. you think you see an animal on the road
- You stop looking in your rearview mirrors
Is feeling tired part of your everyday life?
If you feel constantly tired or have the feeling that your sleep is not restorative, you might be suffering from a sleep disorder. You should consult a physician.
Beware of myths!
Rolling down the window, turning up the radio, singing, changing positions, chewing gum or talking to passengers are not effective and long-lasting solutions. They are really just misconceptions concerning driver fatigue.
The effects of fatigue at the wheel

The effects of a long period of wakefulness: similar to the effects of alcohol
A laboratory study (Williamson and Feyer, 2000) compared the effects of a long period of wakefulness to the effects of alcohol (blood alcohol concentration):
- Between 17 and 19 hours of wakefulness: Physical and mental capacities are comparable to those of a person with a blood alcohol concentration of 50 mg of alcohol/100 ml of blood (0.05)
- After 24 hours of wakefulness: Physical and mental capacities are comparable to those of a person with a blood alcohol concentration of 100 mg of alcohol/100 ml of blood (0.10)
Some tips for keeping your eyes open during long trips
- Rest before setting out and plan for breaks about every 2 hours
- As soon as you start to feel signs of fatigue, stop in a safe location and take a 15- to 30-minute nap. Drink coffee, ideally before you take a nap, as it may take 20 minutes for the coffee to take effect.
- If you can, ask a passenger to take over driving duties
- Whenever possible, avoid driving at night or at times you would normally sleep
- Plan trips by taking into consideration the times when fatigue is most often felt. For example, avoid monotonous and poorly lit roads at night
- Slow down: over time, the extra information you need to process causes fatigue
- Avoid visual fatigue, for example by dimming the dashboard lighting
- Eat light meals and stay hydrated
- Take into account any medical condition that could increase the risk of fatigue
Break or nap?
A break will restore your alertness for a short time. A nap will help you recuperate if you are tired, and you will feel rested longer.
Naps cannot replace a good night’s sleep, but…
In case of serious fatigue, a nap can help you safely continue your trip for some time.
Where is it safe to stop?
In the parking lot of a rest area, a roadside service area, a business or any other area where it is allowed to stop your engine without endangering your safety or the safety of others. You can also stop at a relay village that provides a full range of traveller services.
The shoulder of the road: only in case of emergency
In addition to being prohibited on a highway, stopping on the shoulder is not safe, since there is a risk of collision with other vehicles.
Fatigue, alcohol, drugs and medication: a deadly mix!
Consuming alcohol, medication or drugs, or a mix of these, considerably increases the risk of being involved in a fatal accident. It’s easy to imagine what would happen if we were to add a little fatigue to the mix…
