Most Fatal Types of Motor Vehicle Accidents

During the most recent reporting year of data provided by the Arizona Department of Transportation, we can see that more than 52,000 individuals sustained injuries in vehicle accidents. Additionally, there were 1,294 traffic collision fatalities that same year. Individuals can sustain injuries or lose their lives in any type of vehicle accident, but there are some types of incidents that are more dangerous than others.

Fatal Types of Accidents in Arizona and Nationwide

During the most recent reporting year of data shown from National Safety Council data, we can see that there were nearly 47,000 total motor vehicle-related deaths. These deaths included incidents involving motor vehicles, collisions with fixed objects, pedestrian accidents, and bicycle accidents.


Examining collisions involving motor vehicle accident deaths, we can see that the most fatal types of collisions across the country during 2021 include:

  • Angle collisions (includes T-bone crashes) - 44.8% of fatal collisions
  • Head-on collisions - 29.4% of fatal collisions
  • Rear-end collisions - 17.9% of fatal collisions
  • Sideswipe collisions - 8% of fatal collisions


The Arizona DOT breaks down state data a bit more than the data provided by the NSC. During the most recent reporting year, the following types of incidents accounted for the most vehicle accident fatalities:

  • Angle collisions (includes T-bone crashes) - 13.58% of fatal collisions
  • Left-turn collisions - 12.5% of fatal collisions
  • Rear-end collisions - 10.46% of fatal collisions
  • Head-on collisions - 10.22% of fatal collisions
  • Sideswipe collisions - 6.85% of fatal collisions
  • U-turn collisions - 1.08% of fatal collisions


The type of collision is only one factor that plays a role in the severity of a collision. The type of vehicle is also a major contributing factor. For example, our team of Phoenix personal injury lawyers have handled accident cases involving larger commercial trucks, some of which can weigh up to 80,000 pounds when fully loaded with cargo, which are much more likely to lead to significant injuries or property damage for those involved.


Additionally, incidents involving more vulnerable roadway users, including motorcyclists, bicyclists, and pedestrians, are more likely to lead to significant injuries for those individuals if they are involved in a collision with a larger passenger vehicle.


Additionally, the time of day and weather conditions also play a role in total collisions. Most people drive during the daylight hours, so the vast majority of vehicle fatalities do occur during the day. However, darker conditions and limited visibility do contribute to vehicle accidents. Additionally, roadways can become more treacherous when there is inclement weather.


Getting Legal Help From a Skilled Attorney

If you have lost a loved one due to the negligent actions of another driver, we encourage you to reach out to a lawyer today. A skilled car accident lawyer in Phoenix can examine the facts of your case and help determine the best steps moving forward for your family. Legal action will not change what happened, but it can help bring closure and justice for your family and your loved one.


The personal injury and wrongful death statute of limitations for the state of Arizona is two years from the date the injury or death occurs. Failing to file a lawsuit within this time frame will likely result in the victim or the surviving family members becoming unable to recover compensation for their losses. Please speak to a specialized Phoenix wrongful death attorney as soon as possible after an incident occurs to ensure you get your claims filed on time.
