What Causes the Most Car Crashes?
Most crashes in Missouri trace back to a short list of driver choices and conditions. Knowing which one caused yours matters, because it decides what evidence proves the claim and who can be held responsible.
Excessive Speed and Aggressive Driving
Speeding is the most frequent contributing factor in Missouri fatal crashes. Tailgating, weaving through traffic, and running red lights compound the danger.
Distracted Driving
Cell phone use leads this category, along with eating, adjusting navigation, and passenger distractions. It is a common trigger for rear-end and T-bone collisions.
Impaired Driving
Alcohol, prescription medication, and illicit drugs all slow reaction time. These crashes cluster late at night and over weekends, and they tend to be severe.
Failure to Yield
Intersections, on-ramps, and lane merges are where this happens most, which makes it a leading cause of crashes in St. Louis, Kansas City, and other populated areas.
Improper Lane Changes
Drifting, swerving, or moving over without signalling or checking a blind spot. In rural Missouri it often ends as a run-off-road crash or an overcorrection.
Driver Fatigue
Drowsy driving is a significant cause of highway crashes, particularly on long corridors like I-70 and I-44 where drivers lose focus or fall asleep at the wheel.
Weather and Road Conditions
Heavy rain, snow, and ice reduce traction and visibility across Missouri's seasons, leading to loss-of-control crashes and multi-vehicle pileups on slick roads.
Work Zones and Construction
Sudden lane shifts, narrowed shoulders, and stopped traffic make work zones hazardous, and crashes there often involve drivers who never slowed for the posted change.

High-Speed Car Crashes in Missouri and Illinois
When a car crash occurs at a high rate of speed, the injuries are often catastrophic. The force of a high-speed collision dramatically increases the risk of traumatic brain injuries, spinal cord damage, internal bleeding, and fatalities compared to lower-speed crashes. The higher the speed, the less time a driver has to react and the less effective safety systems like airbags and seatbelts become.
From a legal standpoint, high-speed crashes open the door to additional compensation that standard crashes may not. When a driver was speeding excessively or racing at the time of the crash, a Missouri car accident lawyer can pursue punitive damages in addition to standard compensation. Punitive damages are designed to punish especially reckless conduct and can significantly increase the total recovery for victims.
Proving the other driver was speeding typically requires gathering evidence such as police reports noting a speeding citation, dashcam or traffic camera footage showing vehicle speed, electronic data recorder or black box data from the vehicle, witness statements, and in complex cases, analysis from an accident reconstruction professional. While reconstruction adds cost to a case, it often results in significantly stronger evidence and higher settlements.
How Do You Prove What Caused Your Crash?
Knowing why a crash happened is one thing. Proving it is another, and the proof depends entirely on the cause. A distracted driver is shown by phone records, a speeding driver by the data in their own car, a blown tire by the tire itself. Each of those disappears on its own schedule, which is why the cause has to be identified early.
At the Scene
- 01
Get medical help. Be seen the same day, even if you feel able to walk away. Adrenaline hides pain, and head, neck, and internal injuries often surface a day or two later.
- 02
Photograph the cause, not just the damage. Most people photograph the dented panels and stop there. Capture the skid marks, the debris field, the pothole or missing sign, the blown tire, and where each vehicle ended up.
- 03
Make sure the cause reaches the report. If the other driver was on a phone, smelled of alcohol, or ran the light, say so to the responding officer. A citation or a note in the report is the first independent record of why it happened.
- 04
Ask witnesses what they saw them doing. Not just how the crash looked, but whether the driver was looking down, weaving, or speeding beforehand. That detail is what turns an accident into someone's fault.
In the Days After
- 05
Do not let your vehicle be repaired or scrapped yet. Its event data recorder holds speed, braking, and steering in the seconds before impact, and a failed tire or part is proof you cannot recreate once the car is gone.
- 06
Follow your treatment plan. Keep every bill, record, and receipt. A gap in treatment is the first thing an adjuster points to when arguing your injuries were minor.
- 07
Match the cause to the evidence that proves it. Phone records for a distracted driver, bar and restaurant receipts for a drunk one, maintenance records for a company vehicle, and road complaints for a known hazard. Each has to be requested before it is purged.
- 08
Be careful with the adjuster. You are not required to give the other driver's insurer a recorded statement, and anything you say in one can be used to shift the cause back onto you.
- 09
Talk to a lawyer before you settle. The cause decides who pays. A driver on the clock brings in their employer, a defective part brings in the manufacturer, and a dangerous road brings in a public entity with a far shorter notice deadline.

The insurer opened at $65,000 and later called $101,000 its top offer. Working closely with our client, we proved significant lost wages and settled for $400,000.

Collisions Caused by Drunk Drivers
If a car accident in St. Louis County involves a drunk driver, this can change the complexity of the case completely. This is because the defendant is typically charged with a crime which prevents an attorney’s access to that driver tremendously.
The benefits of having a drunk driver involved in a crash is that police officers would probably have arrived on the scene and filed a police report regarding the details of the accident and the inebriated state of the at-fault driver. As a result, the plaintiff may be able to collect a lot of information they not have not been able to get.
How have Missouri traffic fatality rates changed over recent years?
Missouri’s traffic fatality rates have experienced notable changes over recent years. From 2013 to 2023, the number of traffic fatalities in Missouri increased by 31 percent, and the fatality rate per 100 million vehicle miles traveled (VMT) rose by 13 percent. Despite this decade-long increase, there has been some recent improvement: between 2021 and 2023, traffic fatalities decreased by about 2 percent, and the fatality rate per 100 million VMT dropped by 3 percent.
In terms of raw numbers, Missouri saw 1,030 traffic fatalities in 2022, which decreased to 992 fatalities in 2023 according to the Missouri Department of Transportation (MoDOT). Preliminary data for 2024 indicates a further decrease, with an estimated 955 fatalities, marking a 3.63% reduction from 2023.
However, the state still faces challenges. The Missouri Coalition for Roadway Safety reported that 2022 was the deadliest year since 2006, with 1,057 deaths, highlighting ongoing concerns about risky driving behaviors such as speeding, impaired driving, and failure to wear seat belts.
In summary:
| Year Range | Trend / Statistic |
|---|---|
| 2013 – 2023 | Fatalities up 31%, fatality rate up 13% |
| 2021 – 2023 | Fatalities down 2%, fatality rate down 3% |
| 2022 | 1,030 fatalities |
| 2023 | 992 fatalities |
| 2024 (prelim.) | Estimated 955 fatalities, 3.63% decrease from 2023 |
| 2022 (Coalition) | Deadliest year since 2006 with 1,057 deaths |
Driving at Night
When a crash occurs at night, it can be far more difficult to obtain evidence from the roadway. This is because the investigation is typically delayed by hours at a minimum due to the difficulty that would come with taking photographs and videos of the roadway. It would also be important to obtain skid marks, yaw marks and other photographs of the scene to determine the vehicle’s speed.
Illinois Car Crash Statistics
Illinois roads present their own significant safety challenges. According to the Illinois Department of Transportation, Illinois recorded over 300,000 traffic crashes in recent years resulting in thousands of serious injuries and hundreds of fatalities annually. Cook County, which includes Chicago, accounts for a disproportionate share of Illinois car accident fatalities due to the high volume of traffic and urban driving conditions.
Key Illinois car accident statistics:
- Failure to yield is consistently among the top causes of Illinois crashes
- Distracted driving contributes to tens of thousands of Illinois crashes annually
- Drunk driving fatalities in Illinois typically account for 30 to 35 percent of all traffic deaths
- I-90, I-94, and the Dan Ryan Expressway in Chicago are among the most dangerous roads in the state.
