HB 3349 requires railroad trains or light engines moving freight to operate with at least two qualified crew members, excluding helper services (assisting trains), hostler services (yard locomotive movements), or slow-speed loading/unloading (under 10 mph). Violations incur escalating fines: $1,500 for a first offense, up to $10,000 for third or subsequent offenses. The Missouri Department of Transportation enforces the rule, but the law only becomes effective after Missouri's attorney general confirms federal courts have validated the Federal Railroad Administration's two-person crew standard.

SB 1677, known as "Calvin's Law," requires motorcycle operators to ensure children under 10 years old riding as passengers have both feet on foot pegs and use a proper passenger seat (with medical exemption available), while also mandating protective headgear for all child passengers under 10. It affects motorcycle operators transporting young passengers, with penalties including fines up to $100 for violations involving children under 10. The law also specifies that headgear violations for children under 10 carry a $100 maximum fine (compared to $25 for others), with no court costs or license points for headgear non-compliance. The bill takes effect January 1, 2027.
HB 3365 prevents local governments (cities or counties) from creating rules that specifically target fully autonomous vehicles, such as charging special taxes, fees, or performance standards for them. The bill directly affects local authorities by prohibiting them from enacting ordinances that would apply only to self-driving vehicles or automated driving systems. It establishes a statewide standard to avoid conflicting local regulations, ensuring autonomous vehicle operations face consistent rules across the state. This bill is currently in its early legislative stage, having been introduced in February 2026.
HB 3456 allows utility companies - including investor-owned utilities, cooperatives, and municipal utilities - to install and maintain electric transmission facilities (like high-voltage lines) within highway rights-of-way, subject to safety and engineering standards. It requires Missouri’s Public Service Commission and Department of Transportation to create uniform rules for approving these installations, ensuring public safety, avoiding duplicated corridors, and setting reasonable conditions for construction and maintenance. The bill directly affects utility providers seeking to expand infrastructure along highways and state agencies responsible for transportation and utility regulation. This changes how utilities access highway corridors, streamlining approvals while prioritizing safety and efficient land use.
HB 3538 establishes a "Motor Fuel Tax Fund of 2021" by setting tiered taxes on various fuels used in vehicles. It imposes rates like 17 cents per gallon for regular gasoline, 5-17 cents per gallon equivalent for natural gas/propane (increasing over time), and a supplemental tax rising from 2.5 cents to 12.5 cents per gallon starting in 2021. The revenue from these taxes flows into the fund, which must be used for state road and bridge projects. Businesses that qualify (e.g., commercial fleets using fuel for non-highway purposes) can claim refunds by submitting documentation annually, with refunds paid from the fund.
HB 3515 prohibits Missouri state and local governments from using taxpayer funds to enforce federal emissions regulations on diesel-powered commercial vehicles, including trucks, buses, and transporters. It directly affects state agencies, local officials, and businesses operating these vehicles by banning enforcement actions like inspections or fines related to emissions control devices. The law imposes $100,000 civil penalties on entities employing officials who knowingly enforce such federal rules, and allows lawsuits to recover attorney fees and costs. Violators must pay court costs if sued, with no immunity for government employees acting under federal authority.
HB 3220 modifies learner's permit rules for drivers under 16. It requires applicants to complete 40 hours of supervised driving (including 10 nighttime hours) with parental permission, and mandates accompaniment by a licensed adult aged 21+ (or specific alternatives like instructors or designated relatives). The bill also requires a "PERMIT DRIVER" sticker on vehicles and verifies U.S. residency for permit applicants. These changes directly affect teen drivers and their supervising adults, focusing on structured training and safety compliance.
HJR 192 proposes a constitutional amendment to dedicate specific highway-related revenues to a new "state road fund" for transportation projects. It would require that 73% of the state sales tax on motor vehicles, trailers, and related fuels - after deducting collection costs - be deposited directly into this fund, with the remainder distributed to counties, cities, and a separate transportation fund. The fund must be used exclusively for state highway construction, maintenance, bond payments, and reimbursing counties for roads later adopted into the state system. This change would bypass annual legislative appropriations for these purposes, directly affecting Missouri's highway system, county road costs, and the state highways commission's budget authority.
HB 3249 extends Missouri's existing tax exemption for jet fuel used by airlines in interstate air travel until 2043, replacing a previous expiration date of 2033. The exemption allows airlines to avoid paying state sales and use taxes on jet fuel, provided they have already paid up to $1.5 million in such taxes during a calendar year. Airlines must provide a written certificate to fuel sellers to claim the exemption and may use a direct payment agreement with the state revenue department to manage tax obligations. This change ensures continued tax relief for airlines operating in Missouri's aviation sector without altering the current $1.5 million annual cap on taxable fuel.
