SB 264: Eliminate a defense to the vehicle noise statute

SB 264 amends Montana law concerning motor vehicle exhaust noise. This bill eliminates a specific legal defense for motor vehicle operators cited for exceeding the 95-decibel noise limit. Previously, a driver could not be convicted if they had reasonable grounds to believe their vehicle complied with the noise standard. With this change, that defense is no longer available to those charged with a violation.

SB 428: Generally revise county speed limits

SB 428 revises how local authorities and county commissions can set speed limits on roads. It allows local authorities to adjust speed limits in various areas, such as urban districts, outside urban districts, and school zones, typically requiring an engineering and traffic investigation. A key change is that boards of county commissioners can now set certain decreased speed limits on county roads, including in school zones, without first conducting an engineering and traffic investigation. The bill also specifies signage requirements for altered limits and mandates consultation with relevant bodies for school zones.

SB 433: Revise right-of-way laws for roundabouts

SB 433 revises right-of-way laws for drivers navigating roundabouts in Montana. It establishes that vehicles already in a roundabout have the right-of-way over those approaching it, which must yield. The bill creates specific provisions for towing vehicles, allowing them to deviate lanes for safe passage and requiring other drivers to yield and not pass them within or approaching a roundabout. If two towing vehicles enter a roundabout simultaneously, the vehicle to the left is granted the right-of-way.

SB 380: Generally revise laws related to motor vehicle laws

SB 380 generally revises various motor vehicle laws, impacting drivers, vehicle owners, and the state department. The bill expands the recognition of driver's licenses and identifications to include the Commonwealth of the Northern Mariana Islands. It also revises disability parking permit application requirements, allowing licensed advanced practice registered nurses to issue interim permits. Further provisions update vehicle title, registration, and license plate laws, enable more electronic transactions with the department, and adjust the minimum age for driver's licenses and commercial driver's license expirations.

SB 508: Generally revise driving under the influence laws for THC levels in drivers under 21

SB 508 revises Montana's driving under the influence (DUI) laws concerning tetrahydrocannabinol (THC) for younger drivers. This bill establishes that for individuals under 21 years of age, having any detectable amount of THC in their system constitutes a DUI offense. This means there is no specific THC concentration threshold for drivers under 21, unlike the 5 ng/ml limit for adult drivers. The change applies to any amount of THC, excluding inactive metabolites, found in a driver under 21.

HJ 20: Joint resolution regarding funding for Montana Canada customs ports of entry

HJ 20 is a joint resolution from the Montana Legislature requesting the federal government to increase the hours of service at Montana-Canada customs ports of entry. This resolution aims to enhance trade and allow for increased cross-border travel, which the state legislature states has been impeded by recent reductions in service hours. It directly affects the federal government by formally communicating Montana's request and seeks to benefit businesses and individuals who engage in cross-border activities between Montana and Canada.

HB 387: Revise laws related to highway reconstruction

HB 387 revises the documents the Department of Transportation must file when establishing new or reconstructed highways. It amends current law to require the filing of a "right-of-way plan" instead of a "description and right-of-way plan." This clarifies that private property owners will not receive compensation for new buildings or improvements placed on land after the department files this right-of-way plan for a proposed highway. The bill also states that if no action to acquire the property begins within one year of filing, the highway location establishment becomes ineffective. This act takes effect on July 1, 2025.

SJ 16: Joint resolution on automated vehicles

Senate Joint Resolution 16 is a resolution from the Montana Legislature urging the federal government to establish safety standards for automated vehicles. It specifically calls on the U.S. Congress and the federal Department of Transportation to adopt laws and rules ensuring these vehicles can operate safely in all weather conditions, including snow and ice, and all road conditions, such as mountain passes and open range areas. The resolution highlights Montana's unique challenges, such as a high rate of animal-related car crashes, as a particular concern for automated driving systems.

SB 111: Revising laws related to green lights on snow removal equipment

SB 111 revises state law to limit the use of green lights on public highways. The bill prohibits vehicles from displaying flashing, rotational, or continuous green lights while on a highway. It specifically authorizes the use of green lights for snow removal equipment operated by the Department of Transportation or other government entities. Additionally, police or authorized emergency vehicles serving as on-scene incident command or control vehicles are also permitted to use green lights. This bill directly affects vehicle operators and government entities by clarifying the legal use of green lights on roadways.

SJ 19: Joint resolution to study public transportation

Senate Joint Resolution 19 (SJ 19) requests an interim study on ways to improve passenger transportation and public transit services throughout Montana. The study aims to benefit various residents, including senior citizens, people with disabilities, students, and tourists, particularly in areas currently underserved by transportation options. It will investigate potential solutions, such as establishing a passenger transportation commission and reviewing laws to accommodate autonomous vehicles. The Legislative Council is requested to assign a committee or staff to conduct this study, with final results and recommendations due to the 70th Legislature by September 15, 2026.
