Commercial Motor Vehicles (CMV) play a vital role in the nation’s economy by transporting the products that are needed. By tracking the number of CMV-involved fatalities, MoDOT can target educational and enforcement efforts, as well as improve safety features along Missouri roadways. MoDOT partners with the Missouri State Highway Patrol, St. Louis Metropolitan Police Department, Kansas City Police Department and St. Louis County Police Department to keep people safe while traveling in and around CMVs.

Collaborative efforts from MoDOT and the partner agencies effectively improve roadway safety. Between 2019 and 2023, fatalities involving a CMV have decreased from 1.27 to 1.13 per 100 million CMV vehicle miles traveled. In 2023, Missouri experienced a decrease of 25 fatalities involving a CMV compared to 2022. This resulted in a 2023 fatality rate of 1.13 compared to 1.34 for 2022. The target for 2023 was for fatalities to be below 148 and fortunately this goal was met.

Purpose of the Measure:

This measure tracks annual trends in fatalities involving Commercial Motor Vehicles. This data guides the development and focus of the Commercial Vehicle Safety Plan, which is the plan required to receive Motor Carrier Safety Assistance Program funds.

Measurement and Data Collection:

Missouri law enforcement agencies submit a vehicle accident report form to the Missouri State Highway Patrol to be entered into a statewide traffic crash database. The database automatically updates MoDOT’s crash database system, which is a part of the Transportation Management System. The fatal rates on the charts display the annual fatality and injury rates per 100 million vehicle miles traveled for commercial motor vehicles for these same crashes. The 2023 target was based on a 5.26% improvement rate from the Missouri Commercial Vehicle Safety Plan for 2023 as part of a long-term goal to achieve zero fatalities by the end of 2030.
