The Commercial Motor Vehicle Unit of the Iowa State Patrol is a dynamic, progressive, and professional statewide law enforcement organization dedicated to highway safety. Our Troopers serve and protect the public by patrolling Iowa’s highways and operating our state-of-the-art weigh station facilities. While we enforce all state laws (traffic and criminal) our core mission is in the enforcement of the Federal Motor Carrier Safety Regulations (FMCSR), vehicle size, weight, registration, and travel authority of commercial motor vehicles.


Welcome to the Team photo

“It is an honor to serve Iowans and visitors to our state alongside our commercial motor vehicle partner. We look forward to what the future holds as we work together to maintain a high level of service across the state of Iowa. We appreciate the support of our legislators, Governor Reynolds and the citizens we serve as we forge ahead with a unified state law enforcement presence that will have a lasting impact on the safety and wellbeing of our state.”

Colonel Nathan Fulk
