Many of us are guilty of drowsy driving. We’re tired after a long day at work. We drive home late at night after a busy day. Some of you may even drive for a living.

People don’t take driving while drowsy as seriously as impaired or distracted driving. Is it the lack of attention on the subject?

It’s estimated that 50% of drivers have gotten behind the wheel when feeling drowsy. It is reported that 20% of people have fallen asleep at the wheel. Of that, 1 in 25 drivers say that they have fallen asleep behind the wheel in the last month. The fact is that drowsy driving can be just as dangerous as texting or drinking and driving.

Drivers underestimate the effects of driving while tired. Here we take a look at this important driving safety topic and outline the dangers of drowsy driving, laws, facts, and methods for prevention.

What Is Drowsy Driving?

Drowsy driving, also referred to as tired driving or fatigued driving, is the operation of a vehicle when you are too tired to remain alert behind the wheel. Driving while tired impacts your ability to focus, impairs your decision-making, and can impact your ability to react.

It is estimated that approximately 20% of fatal collisions in Canada involve driver fatigue. That’s 1 in 5 collisions. Many other non-fatal collisions involve drivers who exhibit the signs of drowsy driving.

Why Is Drowsy Driving Dangerous?

Driving while tired impacts your ability to drive. Even though driving tired is responsible for a significant amount of accidents, it does not receive as much attention of impaired driving in Ontario.

Here are some reasons why driving while fatigued is dangerous because :

  • Slower reaction time : A well-rested normal functioning adult brain has a physical reaction time of under 0.2 seconds. Depending on the level of exhaustion you are in, that number could double, or more.
  • Decision making : People can be more impulsive and less rational when they are sleep deprived. Being tired while driving could lead to road rage and poor judgment (racing a yellow instead of waiting).
  • Lack of ability to focus : Coordination, motor skills, and your attention to detail diminishes when you are tired. You need to have clear logical reasoning and processing behind the wheel.
  • Vision and depth perception : Along with slower reaction times, your vision can get blurry and sensitive to light when you are tired. It may be harder to tell how far away other cars are from you.

Drowsy Driving Laws In Canada

There are severe consequences for driving tired, but is it illegal?

There are currently no specific laws related to driving while tired in Canada. However, the impact of driving while tired can cause you to take actions on the road that are punishable by law.

Even though the dangers are well documented, it is not against the law to drive while tired. However, it is strongly discouraged. The government has invested in legislative acts and awareness campaigns in an attempt to educate drivers about the dangers of fatigued driving.

What Are The Warning Signs Of Tired Driving?

Drivers don’t think twice about feeling extremely tired while driving. They press on instead of taking a break on long drives, and many drive when they should be resting.

Since there is no test for drowsy driving, it can be difficult to know when you are too tired to drive. But there are warning signs to indicate when you should consider taking a break or not driving.

Here are the common warning signs that you may be too tired to drive :

  • Yawning frequently
  • Heavy eyelids and head nodding
  • Trouble keeping your eyes open
  • Trouble focusing
  • Wandering thoughts
  • Trouble remembering the last few kilometres driven
  • Missing a road sign or exit

How Does Lack Of Sleep Affect Driving?

According to a Canadian Association of Chiefs of Police report, 20% of fatal collisions are caused by drowsy drivers. Here are some of the effects of drowsy driving on your ability to drive :

  • Drifting out of your lane : Veering in and out of your lane. Trouble staying in your lane.
  • Missed exits : Missing turns.
  • Road signs : Missing stop signs, traffic lights and other traffic signs.
  • Inconsistent speed : Speed continuously increasing and decreasing.
  • Speeding : Driving above the speed limit. Failure to adjust speed to speed limits.
  • Stopping issues : Sudden braking and stopping close to other vehicles.

If you experience any of these signs, consider taking a break, switching drivers, or getting some sleep before driving.

Who Is Most Likely To Drive Drowsy?

There are various reasons and specific groups of driving who are more prone to driving tired.

Here are the types of drivers who are at higher risk than others :

  • Poor sleep habits : People who do not get enough sleep tend to have issues focusing.
  • Professional drivers : People who drive for a living, such as commercial drivers, spend long hours on the road.
  • Shift workers : Working odd hours can impact tiredness.
  • Sleep disorders : People with sleep disorders regularly operate tired.
  • Medication : People on medication may experience sudden drowsiness.
  • Adults with children at home : Parents often have a sleep deficit.

Drowsy Driving vs. Drunk Driving

Just how dangerous is drowsy driving? Many experts suggest driving while tired can have the same or similar impairment effect as alcohol.

According to the National Sleep Foundation :

“Drowsy driving is dangerous because sleep deprivation can have similar effects on your body as drinking alcohol. Being awake for 18 hours straight makes you drive like you have a blood-alcohol level of .05 (for reference, .08 is considered drunk). If you’ve been awake for a full 24 hours and drive—say, after a night where you just couldn’t fall asleep—it’s like you have a blood-alcohol level of .10.”

Both types of impairment make it difficult for drivers to focus on driving and negatively impact the speed and accuracy of a driver’s decision-making capabilities.
