Having an understanding of the Missouri car accident statistics can help some drivers learn when and where to be more cautious. It can also provide more information about the common causes and circumstances of accidents in the state.

Impaired Driving Crashes in Missouri

When drivers operate their vehicles under the influence, it increases the likelihood of a crash. They may be under the influence of alcohol or drugs, including prescription drugs. Being impaired lowers your reaction speeds when driving, and it also limits your ability to make rational decisions. All of this makes crashes more likely.

Alcohol was the probable contributing cause in 5,480 crashes, based on MSHP data in 2021. This included 163 fatal crashes, which resulted in 176 fatalities. It resulted in 2,111 injury crashes, and 3,206 crashes only caused property damage.

In the same year, there were 213 fatalities in car accidents that involved a driver who was impaired by a substance, which includes drugs, alcohol, or a combination of these. Of the 199 drivers who were substance-impaired, 80.9% were male, and 27.1% of all substance-impaired drivers were between the ages of 20 and 29.

Other Common Causes of Crashes

Although driving impaired is dangerous, it is not the only cause of car accidents. It is not even the most common probable contributing cause of accidents in the state. The most common cause of fatal crashes, according to the MSHP, was improper lane changes, while the most common cause of injury and all other crashes was failing to yield.

Distracted driving was a probable cause in a total of 17,417 crashes, resulting in 4,678 injury crashes and 6,821 injured persons. Distracted driving caused 87 fatal crashes and 89 fatalities. Out of the 1,016 fatalities reported in 2021, 71 involved a distracted driver. 80.3% of the distracted drivers were male, and 30.6% of all distracted drivers that year were between the ages of 20 and 29.

In the same year, there were 548 fatalities in car accidents that involved an aggressive driver. Of the 497 reported aggressive drivers, 78.3% were male. 25.8% of aggressive drivers were between 20 and 29, and 22.3% were between 30 and 39.

If you are involved in an auto accident, you can file a claim with the insurance provider of the driver who caused the accident.
