Missouri Motorcycle Accident Statistics

The rising number of motorcycle accidents that occur on Missouri’s highways continue to pose a serious safety issue for its road users. The Missouri Department of Transportation (MoDOT) states that there were 138 motorcycle accident deaths in 2024. The preliminary data from MoDOT and the Missouri State Highway Patrol does indicate that motorcycle deaths declined slightly in 2025, which officials attribute to recent safety campaigns and enforcement efforts. However, the dangers faced by motorcyclists are still very real. In this article, we list selected statistics on statewide motorcycle accidents, study fatal crash patterns, and examine safety trends and the factors that contribute to motorcycle crashes, injuries and deaths in Missouri.

Missouri Motorcycle Accident Statistics Overview

Even though motorcycles account for only about 2.5% of registered vehicles in Missouri, they are involved in 17% of all traffic accident deaths in the state. Based on MoDOT reports, motorcycle accident fatalities tend to be concentrated in the state’s more populated regions, with a number of motorcycle crashes happening in Kansas City, St. Louis, Springfield and St. Charles. Also, in 2024, the 138 motorcycle accident fatalities that occurred in Missouri represent a slight decrease from the previous year. However, that number still accounted for about 15% of all statewide traffic fatalities, according to MoDOT.

Further, 82% of motorcycle crashes in 2023 resulted in injury or death. During the same year, 98% of those who died in motorcycle-related crashes on Missouri roadways were the motorcycle riders. Also, 62% of all motorcycles involved in deadly crashes in Missouri, collided with another motor vehicle. Statistics show that there is a 38% increase in the likelihood of death if the rider did not wear a helmet.

In addition to fatalities, a significant number of motorcycle-involved collisions in Missouri result in catastrophic injuries such as traumatic brain injuries, spinal cord damage, fractures and road rash. Riders are especially vulnerable in an accident because motorcycles provide little physical protection.

Missouri Motorcycle Fatalities by Year

Metric	2023	2024 (Most recent)
Total Missouri roadway deaths	989	954
Motorcycle fatalities	175	138
Motorcycle fatalities as % of all roadway deaths	17.7%	13.9%

The number of Missouri motorcycle accident fatalities had shown a relatively stable pattern before 2020. But, deaths from motorcycle crashes spiked after the COVID-19 pandemic and the change in the state’s law repealing helmet use. In August 2020, Missouri changed its helmet requirement, allowing riders over the age of 26 to ride without a helmet, if they carry health insurance. State transportation officials have since pointed to a strong correlation linking that change in helmet laws and rising fatality rates.

This increase was apparent in 2021 and continued through 2023, when Missouri recorded a historic high of 175 motorcycle accident fatalities. MoDOT reported that motorcycle fatalities surged by 50% compared to averages prior to the repeal. Preliminary numbers for 2024 showed motorcycle fatalities declining by 23% ­— the lowest level since the helmet law repeal.

Missouri Motorcycle Injury Statistics

Motorcycle accidents often result in serious or catastrophic injuries because motorcyclists have much less physical protection compared to occupants of passenger vehicles. Motorcycle riders are directly exposed to the roadway, surrounding vehicles, etc. during impact. According to the MoDOT statistics, about 82% of motorcycle crashes in 2023 resulted in either injury or death, which shows how vulnerable motorcyclists can be in these types of crashes.

As motorcycles lack structural protections such as airbags, seat belts or steel frames, even relatively low-speed collisions can throw riders from the motorcycle and cause significant injuries. High-speed crashes and incidents involving drivers further increase the likelihood of catastrophic injury or death.

Each year, over 2,000 Missouri motorcyclists suffer injuries ranging from broken bones to disabilities that can affect them for the rest of their lives. Some of the common injuries suffered in motorcycle accidents include traumatic brain injuries, spinal cord damage, broken bones, severe road rash, internal organ injuries and trauma to the hips, legs, shoulders and wrists. Head injuries remain one of the most serious risks, especially in crashes where motorcyclists or their passengers are not wearing helmets. Even when riders survive in these cases, brain and spinal cord injuries can cause lifelong cognitive impairment, paralysis and chronic pain — all leading to substantial medical expenses for victims and their families.

Most Common Causes of Motorcycle Accidents in Missouri

Motorcycle accidents in Missouri often occur because of reckless or negligent behavior on the part of other drivers. These reckless actions put motorcyclists in harm’s way. One of the most common dangerous scenarios is drivers failing to see motorcycles in traffic. Because motorcycles are smaller and less visible than passenger vehicles, motorists frequently overlook them when changing lanes, merging or entering intersections. These types of situations lead to potentially deadly side-impact collisions.

Failure to yield: Left-turn collisions are another leading cause of motorcycle accidents across Missouri. These collisions usually happen when a driver attempts a left turn at an intersection without noticing an oncoming motorcycle. A crash can also happen is a motorist misjudges the approaching motorcycle’s speed. In many cases, the motorcyclist has little time to react. Such collisions often result in severe or fatal injuries.

Distracted driving: Drivers who text, use navigation systems or engage in other distractions may fail to notice approaching motorcycles until it is too late. Distractions can be visual or cognitive in nature. Even a minor distraction can cause a collision that can result in life-changing injuries for motorcyclists.

Impaired driving: When drivers operate under the influence of alcohol and/or drugs, the consequences can be devastating for motorcyclists. Drivers who are under the influence may not have the ability to react in time to avoid a motorcycle crash.

Speeding: Driving at an excessive rate of speed can also increase the likelihood of serious injury accidents. Motorcyclists are particularly vulnerable in these types of situations.

Rural road risks: Rural highways throughout Missouri present additional dangers for motorcyclists. High speeds, narrow roads, sharp curves and limited lighting can create dangerous conditions for motorcyclists.

Unsafe lane changes: This is also a major factor in motorcycle accidents. When drivers fail to check mirrors or blind spots before moving across lanes, there’s a risk of sideswiping a passing motorcyclist or forcing him or her off the roadway.

Missouri Helmet Statistics

Missouri’s motorcycle helmet laws changed significantly in 2020 when the state repealed its longstanding helmet requirement for all riders. Under the revised law, motorcyclists age 26 and older are allowed to legally operate a motorcycle without a helmet if they have health insurance or meet certain insurance coverage requirements. Supporters of this change say this is a matter of personal freedom and choice. However, public safety officials and safety advocates still raise concerns about the potential increase in serious motorcycle-related injuries and fatalities.

The safety concerns seem to have been justified as deaths since the repeal among motorcyclists who were not wearing helmets surged across the state and 73 of Missouri’s 153 motorcycle fatalities in 2022 involved riders who were not wearing helmets. These statistics have added validity to discussions about motorcycle safety and the effectiveness of helmet laws in reducing deadly crashes.

National statistics and reports from the National Highway Traffic Safety Administration (NHTSA) show that a DOT-compliant helmet is the most effective way for motorcyclists to protect themselves from serious head injuries. Safety data consistently show that helmets help reduce the risk of traumatic brain injuries, skull fractures and fatal head trauma during collisions. Helmets also provide face and eye protection.

Although Missouri law now allows some adults to ride without helmets, state safety officials and transportation agencies continue encouraging helmet use. Many experts emphasize that wearing a properly fitted DOT approved helmet can significantly improve a rider’s chances of surviving a serious motorcycle accident and minimizing long-term injuries.

Dangerous Roads and Areas for Motorcycle Riders in Missouri

Motorcyclists face dangerous roadway conditions in different parts of the state. The Kansas City and the St. Louis metro areas present challenges tied to traffic congestion. Motorcyclists may encounter drivers making sudden lane changes, motorists who are distracted or heavy rush-hour traffic. Interstate travel near these urban centers also increases crash risks because of higher traffic volumes and fast-moving vehicles.

Outside the cities, rural highways create different hazards. Many Missouri traffic fatalities occur in rural areas, where riders often travel at higher speeds on two-lane roads with narrow shoulders and limited lighting. Also, limited visibility caused by hills, trees, farm entrances and inclement weather can reduce the time riders have to react to hazards.

Winding highways and curving two-lane roads in the Ozarks region attract motorcyclists who like to ride during the weekends. Although these scenic routes are popular among motorcyclists, the sharp curves, uneven pavement and wildlife crossings can increase the likelihood of serious crashes. Riders who are unfamiliar with such roads in the Ozark region can underestimate how quickly road conditions and elevation changes pose a danger.

Urban vs Rural Motorcycle Accident Trends

Motorcycle accidents can vary significantly between urban and rural areas in Missouri. Drivers who fail to notice motorcyclists in cities such as Kansas City and St. Louis, cause crashes. These types of collisions occur often at intersections while turning, merging or changing lanes, etc. Heavy congestion, stop-and-go traffic and distracted driving also increase the risk of urban motorcycle collisions.

Rural Missouri presents a different set of dangers to motorcycle riders. Higher-speed crashes are more common on open highways and curving two-lane roads, especially in the Ozarks. Limited street lights, narrow shoulders and reduced visibility at night make it harder for riders to detect hazards in time. Crashes in rural areas tend to be more severe as motorcycles collide at greater speeds and emergency response times are typically longer in remote areas. Delayed medical treatment can worsen injuries after a serious crash.

When are Motorcycle Accidents Most Likely to Occur?

Motorcycle accidents in Missouri are most common during the spring and summer riding season when warmer temperatures bring more riders onto the road. We see higher crash rates during the weekends and holidays, particularly in scenic areas such as the Ozarks where riders travel longer distances during summer months. In these cases, fatigue can become a factor.

Weekend crashes are also linked to heavier traffic, social events that include alcohol consumption, etc. Nighttime riding can also be dangerous because reduced visibility makes it harder for drivers to see motorcycles, especially on rural highways and poorly lit roads. Headlight glare, wildlife crossings and limited reaction time can further increase the risk of serious collisions after dark.

Holiday traffic add to crowded roadways and bring impatient drivers while changing weather conditions including rain and snow can create slick roadways that pose a hazard to motorcycle riders. Such factors can make certain seasons, times and travel periods especially dangerous for riders.

Missouri Motorcycle Accident Statistics Compared to National Trends

Motorcycle accident trends in Missouri closely reflect national patterns, with motorcyclists representing a disproportionately high percentage of roadway deaths compared to the number of motorcycles on the road. Across the United States, motorcycle riders face a significantly greater risk of fatal injury than occupants of passenger vehicles. This is particularly true when it comes to crashes involving high speeds and multiple vehicles.

Missouri, like other Midwestern states, sees more collisions on rural highways, particularly at night. The state’s mix of congested urban areas and two-lane rural highways contribute to crash risks for motorcyclists.

In addition, discrepancies in helmet laws can have an impact on motorcycle fatality trends. Missouri allows some riders to operate motorcycles without helmets, and this has left safety advocates concerned about motorcyclists suffering catastrophic injuries that could leave them with lifelong disabilities or reduce their long-term survival rates.
