HB 512 mandates that all new school buses purchased on or after January 1, 2026, must be equipped with lap-shoulder belts for each passenger. School districts using these buses would be required to adopt and enforce a seat belt usage policy and ensure belts are properly maintained. The bill provides exceptions for school districts that cannot afford such buses, following a public vote. Additionally, it limits the liability of the state, counties, and school districts in personal injury cases where passengers fail to use or improperly use the belts, provided an enforceable policy is in place.

HB 159 revises Montana's rural improvement district laws to explicitly allow districts to be created for maintaining existing public improvements (like roads or drainage systems), not just building new ones. It simplifies the process by removing the need for a petition if all property owners within the proposed district waive their right to protest its creation. The bill also adjusts petition requirements for road maintenance districts, requiring only 50% consent of property area if all roads to be maintained are public improvements. This directly affects rural property owners and county commissioners by making it easier to form districts focused on upkeep rather than new construction.

HB 97 allows trucks to travel in coordinated groups (called "platoons") using technology to maintain closer, synchronized spacing on Montana highways. It requires all drivers operating in a platoon - both the lead vehicle and anyone who can take control - to hold a commercial driver's license (CDL). The Department of Transportation can restrict platooning during dangerous road conditions and must consult stakeholders before creating safety rules. The law applies to trucking companies and drivers on public highways and takes effect July 1, 2025.

HB 43 revises Montana's motor vehicle traffic laws to improve clarity and consistency. It specifically defines "paved shoulder" to allow bicyclists to operate on shoulders (not just paved roads), updates rules for yielding to emergency vehicles, and clarifies when passing school buses is permitted. The bill also reorganizes traffic definitions and amends parking permit rules to better protect accessible parking spaces for people with disabilities. These changes directly affect drivers, cyclists, and emergency responders by standardizing road usage and accessibility requirements. The bill was signed into law by Montana's Governor on March 27, 2025.
