Car accidents happen every day. While some drivers may blame it on bad luck, the most common causes of car accidents in Canada can be traced back to environmental factors and driver behaviour. Understanding these factors can help you protect yourself, your passengers, other drivers, pedestrians and your vehicle.
This guide goes over the most common reasons why Canadians are involved in accidents, practical prevention tips, common injuries and how having the right insurance coverage may help in your time of need. Key takeaways:
Distracted driving, speeding and impaired driving are among the leading contributors to severe car accidents across Canada.
Poor road and weather conditions can increase your risk behind the wheel.
Small habit changes like not using your phone, installing winter tires and planning your route ahead of time can lower your risk of being involved in a collision.
Accident benefits coverage may help cover medical and rehabilitation expenses and lost wages following a collision, subject to provincial rules and policy limits (mandatory in most provinces).
Collision coverage covers any repair or replacements your vehicle requires when you’re involved in a car accident (optional).
Comprehensive insurance covers repairs or replacements needed following non-collision damages arising from theft, vandalism, fire and severe weather conditions.
When we say “most common causes of car accidents,” it’s important to clarify what we’re measuring. In Canada, data is collected at both a federal and provincial level, and each source may vary in terms of definition. Here’s a general overview of what we’re talking about:
Driver behaviour: Distractions, speeding, impairment, fatigue and aggressive driving.
Violations: Failure to obey stop signs, right-of-way-rules and signals.
Environment: Weather, visibility, road surface conditions.
You’ll notice that sources vary by province. We’ve included both national and provincial context when possible.
Across Canada, motor vehicle accidents are a significant public safety concern. In 2023 alone, Transport Canada reported 1,964 fatalities and 9,261 serious injuries. Although fatal crashes account for a small percentage of total car accidents, it’s important to remember that serious injuries and property damage are still highly prevalent. According to the Canadian Association of Road Safety Professionals (CARSP), 25% of fatal crashes in 2023 involved speeding, which was approximately 10% higher than the previous year.
At the provincial level, trends differ. For example, Alberta recorded 119,070 collisions with 2,164 serious injuries, while Saskatchewan reported 28,238 crashes, resulting in 92 deaths in 2023. Further, intersections, winter weather conditions and time of day are also a contributing factor to collision risk. Let's take a look at a data table:
Cause
Statistics
Intersections
27% of fatalities and 41% of severe injuries occurred at intersections in 2023.
Winter conditions
Approximately 30% of fatal collisions involve icy, snowy or wet roads.
Seasonal trends
Winter months (Dec to Feb) see the highest number of collisions.
Night driving
Evening and night collisions have higher odds of leading to serious car accidents and injuries.
Many motor vehicle crashes are directly influenced by driver behaviour. The most common behaviours behind the wheel that lead to crashes include:
For quite some time, distracted driving has been one of the leading causes of collisions in Canada. Distracted driving is a fairly broad term that can include any activity that directs the driver’s attention away from the task of driving. Everything from eating a snack or drinking water to talking on the phone, texting or changing the radio station are considered distractions. Speaking to another passenger in the car, such as to a child in the backseat, is another example of distracted driving.
Distracted driving statistics are alarming. According to Transport Canada, distracted driving contributes to approximately 22.5% of car accidents each year.
Here are some alternatives to distracted driving:
Avoid calls in heavy traffic and when road conditions are unfavourable.
Preset your GPS, music and climate controls before you head out on the road.
Use hands-free devices only if absolutely necessary.
Ask a passenger to help you with tasks like navigation or adjusting the radio, so you can focus on driving.
Speeding is another common cause of collisions. When we travel at faster speeds, we have less time to react to situations around us. If you are forced to react to something suddenly, your odds of being able to brake in time go down if you’re speeding and may cause you to lose control.
Driving over the speed limit is responsible for approximately 20% of all fatal crashes in Canada in 2018, according to Transport Canada. High-speed collisions often have a more significant impact on passengers, such as serious injuries or even fatalities, not to mention the impact on your car, with vehicles more likely to suffer major damage or even be totalled.
Instead of speeding, do this:
Take note of the posted speed limit and adjust your vehicle speed for road conditions, traffic and weather.
Use cruise control on highways when appropriate to maintain a consistent, safe speed.
Allow extra time to travel so you don’t feel pressured to increase your speed.
Impaired driving in Canada is illegal and one of the leading causes of severe collisions. Alcohol and drugs can reduce driver reaction time, impair coordination, affect vision, and compromise your ability to concentrate.
In Canada, approximately 30% of all fatal crashes involve impaired driving. Even a small amount of alcohol, illicit drugs or prescription medications can increase your risk of being involved in a fatal accident.
Always choose safety and take precautions:
Never get behind the wheel after consuming alcohol or drugs. Use taxis, ride share apps, call a friend, or have a designated driver for the night.
Be aware of medications that may impair your driving, even if they have been prescribed to you.
Plan ahead on nights out or long trips to ensure you have a safe ride home.
Aggressive driving behaviours include tailgating, repeated honking, making rude gestures and yelling at other drivers or pedestrians. Aggressive driving increases the risk of dangerous behaviours such as speeding, failing to signal, weaving through traffic and tailgating. The Canada Safety Training Centre reports that aggressive driving contributes to over 25% of serious crashes across Canada.
If you ever run into a hostile driver, choose to:
Stay calm in traffic and practice deep breathing.
Maintain a safe following distance and obey traffic signals.
Avoid engaging with aggressive drivers. Do not retaliate or escalate conflict.
It’s common for people to get behind the wheel while tired. Whether they’re exhausted after a long day of work or during their early morning commute, people lead exhausting, stressful lives. That said, falling asleep behind the wheel is a quick way to get into a collision. The Canadian Association of Road Safety Professionals (CARSP) reports that fatigue is the leading cause of 20% of all accidents in developed countries.
Always rest up before a drive:
Avoid driving during the early morning or late at night if possible.
Switch on-and-off with another driver during road trips.
Take regular breaks, ideally every 2 hours, especially when travelling long distances.
Ensure you get enough sleep before long trips.
Intersection errors, traffic signals, and other errors are all common causes of car accidents. Understanding how to properly navigate these signals, stop signs and turns is essential to reducing your risk. Here's what you should know:
Studies show that yellow traffic lights, in particular, increase the odds of a collision because they force the driver to make a split-second decision. Misjudging yellow lights can lead to collisions, particularly t-bone car accidents at high speeds. Running red lights is another serious risk associated with high-severity accidents.
Here's what you should do:
Approach yellow lights with caution. If you can’t safely stop, proceed carefully while scanning the intersection for other vehicles.
Never run a red light. A complete stop and awareness of other drivers is essential to preventing vehicle collisions at intersections.
The problem with stop signs is that many drivers do not take them as seriously as traffic lights. Although they are to be obeyed at all times, some motorists choose to engage in risky behaviours, such as rolling stops over complete stops or failing to yield to other cars using the right-of-way system, which can lead to rear-end collisions. As there are no traffic lights, it is up to each motorist to decide when it is safe to proceed.
Ensure that you do the following:
Come to a full stop, even at low-traffic intersections.
Scan left, right and ahead before proceeding.
Use the “1,2,3” counting method before proceeding to ensure you have fully stopped.
Misjudging turns includes left turns at intersections, right-hand turns and U-turns. Basically, anytime a driver has to judge oncoming traffic before making a turn, the odds are higher of an accident occurring. Failing to use a turn signal and driving in inclement weather makes turning even more risky. T-bone collisions are a common type of collision that occurs when a driver is making a left-hand turn at an intersection.
Here's how you can prevent yourself from getting into a traffic accident:
Always signal in advance before completing your turn.
Assess gaps in oncoming traffic and wait for there to be no other road users at busy intersections.
Adjust your speed when turning in bad weather or in low visibility conditions.
Beyond driver behaviour, the local environment and road conditions are also major contributing factors to collision in Canada. Let's take a look:
Extreme weather conditions often make roads slicker, reducing traction and, therefore, minimizing a tire’s ability to grip the road. This can result in slower brake times and decreased handling capabilities. Examples of inclement weather include heavy rain, fog, snow, ice and hail. Most of these conditions are more likely to occur in the winter, but you can face various adverse weather conditions year-round.
Always be cautious and adjust your driving to fit road conditions:
Install snow tires on your vehicle in the wintertime as they can improve traction on snow and ice.
Clear all glass surfaces, mirrors and lights before you head out on the road.
Use low beam headlights in fog, snow and heavy rainfall to improve visibility.
Leave extra room between you and other vehicles to avoid road accidents in poor weather conditions.
Smooth steering, acceleration and braking can help you maintain control.
Poor visibility, especially at night, is another common factor that contributes to road accidents. Dirty headlights can create halos and blur light, causing glare from wet roads and oncoming traffic. Wildlife also poses a risk in rural areas, creating dangerous conditions, especially at night.
Follow these safety tips:
Ensure your headlights are properly aimed and the lenses are cleaned.
Keep your windshield, mirrors and windows clean.
Dim your interior lights and turn off cell phone screens to reduce distractions.
Always scan your surroundings to prevent car crashes in wildlife-prone areas.
Use your high beams responsibly. Switch to low beams when other vehicles are approaching.
Driving near dangerous road hazards can also increase your risk of getting into a collision. Examples of road hazards include potholes, manhole covers, sharp curves, steep inclines, roads without markings or signs, and surface changes, e.g. from paved asphalt to a gravel or dirt road. Any of these hazards can make it more dangerous to drive. They also increase the odds of your car being damaged.
Here are some precautions you should keep in mind:
Approach hazards slowly.
Maintain proper lane positioning.
Avoid abrupt swerves.
Take a defensive driving course in your area.
Report hazards to local authorities to prevent other car accidents.
Property damage is only one possible outcome of a car accident. Serious crashes often lead to traffic fatalities and serious injuries. Some of the most common injuries vehicle collisions can cause and which insurance policies can come in handy afterward:
Traumatic brain injuries (TBI) are sudden injuries that cause damage to the brain. They occur when your head suffers a bump or blow or if an object penetrates your skull in any way. TBIs range from mild to moderate to severe. Severe cases of TBI can lead to a coma or even death.
Spinal cord injuries are those that cause damage to the spinal cord or the nerves at the bottom of the spinal canal. Spinal cord injuries can significantly impact bodily functions. For instance, they can result in a loss of movement, a loss of bladder or bowel control, and a loss of sensation (paralysis).
It is also not uncommon for car accidents to result in broken bones. Affected bones could be anything from ribs and arms to legs, ankles and wrists. Although most broken bones can be repaired, this can take time. Minor cases, such as fractures, may be fixed with a simple cast. Meanwhile, severe breaks could require surgery to repair.
Luckily, any medical expenses, including postoperative care, such as physical therapy, may be covered by accident benefits coverage or third-party liability car insurance.
Lacerations and road rash are perhaps the most minor examples of injuries that may come from a collision.
Even a minor rear-end collision can cause whiplash, neck strain and other soft tissue injuries. Again, accident benefits will cover expenses related to your treatment. If another driver is at-fault, their liability insurance will provide you with compensation.
Beyond accident benefits, which is a mandatory insurance policy all Canadian motorists must have, there are optional plans you can add to your portfolio:
Comprehensive: Comprehensive insurance generally includes repairs or replacements your vehicle requires following theft, vandalism, fire and adverse weather conditions.
Collision: Repairs or replaces your vehicle following a car accident you’re responsible for, subject to deductibles and policy terms.
If you ever get into a car accident, follow these steps:
Assess for injuries.
Call 911.
Document the scene with photos and videos.
Contact your insurance company.
Work with your adjuster.
Get compensated.
Rules vary by province. Take a look:
High beam etiquette: Dim your beams with 150 metres of oncoming traffic and 60 m when following another vehicle.
Distracted driving penalties: Distracted driving can lead to hefty fines, demerit points, license suspensions, vehicle impoundments and other consequences.
Winter tire incentive: Some provinces like BC, Alberta and Ontario offer discounts when you install winter tires on your vehicle during the winter.
Even experienced drivers are at risk of being involved in collisions when poor driving habits and adverse weather/road conditions are involved. By practicing safe driving techniques and planning ahead, you can reduce your risk of a collision and remain safe behind the wheel. And, with the right insurance coverage in place, you can rest assured that you’ll be protected financially in the aftermath of a collision.
