 Commercial Motor Vehicles play a vital role in our nation’s economy by transporting the products we need. 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.

While efforts from MoDOT and the partner agencies are effective in improving safety on roadways, Missouri has experienced an increase in the number and rate of fatalities involving CMVs. Between 2014 and 2018, fatalities involving a CMV increased by 29.2% and the fatality rate increased from 1.17 to 1.32 per 100 million CMV vehicle miles traveled. In 2018, Missouri experienced an increase of 19 fatalities involving a CMV as compared to 2017. This resulted in a 2018 fatality rate of 1.32 compared to 1.15 for 2017. The target for 2018 was 116 fatalities and unfortunately the goal was not 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 rates on the chart display the annual fatality rates per 100 million vehicle miles traveled for commercial motor vehicles for these same crashes. The targets are based on a 9% improvement rate from the immediate prior year fatalities.
