Generally revise motor vehicle traffic regulation laws
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.
