Why Missouri's Hands Free Law Costs a CDL Holder More

Missouri's phone law turns three this week

The Siddens Bening Hands Free Law took effect in Missouri on August 28, 2023. Codified at Missouri Revised Statutes 304.822, it bars an operator from physically holding an electronic communication device or from texting, dialing, retrieving data, or watching video while driving. The statute carried a grace period, so officers could only warn until January 1, 2025. Real enforcement is barely a year and a half old.

The first year of citations produced more than 1,400 of them statewide, according to Missouri State Highway Patrol figures reported by ABC 17 News in December 2025. The mid Missouri troop covering the I-70 corridor wrote 94 between January 1 and December 8. Ninety were for device use, three involved property damage, and one involved a death. If you run commercial truck insurance in Missouri lanes between St. Louis, Columbia, and Kansas City, those are your numbers.

The secondary offense limit protects cars more than it protects trucks

Two subsections read like a shield. Subsection 12 says no person shall be stopped, inspected, or detained solely for a violation of this section. Subsection 8 says a violation shall not be used to establish probable cause for any other violation. For a passenger car driver, that mostly means something else has to go wrong first.

A truck is different, and not because the law says so. A commercial vehicle already gets stopped for reasons that have nothing to do with a phone. A weigh station, a roadside inspection, a light or credentials check. The citation needs no probable cause of its own when the stop was already going to happen. Secondary enforcement is a real limit for a driver who is never inspected and a thin one for a driver inspected several times a year on I-70 and I-44.

There is a second asymmetry. Subsection 7 requires an officer who stops a noncommercial motor vehicle for a violation of this section to inform the operator of the right to decline a search of the device. By the statute's own wording that notice attaches to the noncommercial stop. The driver most likely to be asked about the phone is the one the notice was not written for. Decide your answer to that question in the office, not at the roadside.

The federal rule is the expensive one

Missouri's fine ladder is modest. Up to $150 for a first violation, $250 with one prior inside 24 months, $500 with two or more, and $500 in a work zone or school zone. The criminal tiers are where it gets serious. Property damage over $5,000 is a class D misdemeanor, serious physical injury is a class B misdemeanor, and a death is a class D felony.

The federal side never went away. Under 49 CFR 392.80 and 392.82, no driver may use a hand held mobile telephone or engage in texting while driving a commercial motor vehicle, except to reach law enforcement or emergency services. FMCSA puts the civil penalty at up to $2,750 for the driver and up to $11,000 for an employer who allows or requires it, both adjusted for inflation. Under 49 CFR 383.51 the conviction is a serious traffic violation, so a second from a separate incident inside three years disqualifies the CDL for 60 days and a third for 120 days. Missouri writes the ticket. The federal scheme decides what it is worth.

What a $150 ticket does to a renewal

A hand held device violation lands in the Unsafe Driving category of the Safety Measurement System, which an underwriter reads before quoting you anything. A large fleet averages one violation away across hundreds of inspections. A three truck operation cannot. One conviction on one driver can move a small carrier's percentile enough to change the renewal price, a far bigger bill than the fine ever was. Our guide on how CSA scores affect your premium shows how that math lands.

What it does to a claim

The real exposure is what the citation does after a crash. A rear end collision with no phone in the record is an argument about following distance and reaction time. The same collision with a device conviction in the driver's history is an argument about a choice, and that is what moves a case out of ordinary negligence. Add a statute that makes serious injury a misdemeanor and a death a felony, and the posture of the whole file changes. Your commercial auto liability limit is the only thing standing behind that argument.

Three things worth doing this week

Put the phone rule in writing and have every driver sign it, because the employer penalty reaches carriers who allow or require the behavior and a signed policy is your evidence that you did neither. Buy a mount and a hands free setup for every truck, since the statute expressly permits a voice operated or hands free feature for a commercial operator who stays seated and belted. Pull motor vehicle records once a year so a conviction never reaches your underwriter first.
