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.
