SB 359: Revise traffic laws related to distracted driving

SB 359 would have prohibited holding or using handheld mobile devices while driving in Montana, including texting, watching videos, or recording content, except for hands-free navigation or voice calls. It would have required drivers to use hands-free devices for calls and navigation, with exceptions for emergency vehicles, law enforcement, and work-related radio use. Violations would have carried civil penalties of $75-$149 for a first offense and $150-$250 for repeat offenses. The bill aimed to reduce distracted driving by clarifying restrictions on device use and defining terms like "portable wireless communication device" in Montana law.

HB 312: Revise speed limit laws

HB 312 revises speed limit laws for drivers in Montana. The bill increases the daytime speed limit to 75 miles per hour and the nighttime speed limit to 70 miles per hour on national highways that have been expanded to four lanes and are at least 15 miles long, except in special speed zones. It also updates the penalty section to reflect these new speed limits, maintaining that minor speeding violations (up to 10 mph daytime or 5 mph nighttime) are generally not recorded against a driver's record, with specific exceptions for commercial drivers or high-speed violations on interstates.

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.

HB 773: Revise laws related to metropolitan planning orgs and transportation planning

HB 773, known as "Noah's Act," aimed to streamline transportation planning by reducing redundant reviews for certain projects. It would have eliminated the need for the Transportation Commission to re-review long-range transportation plans and associated projects that were already adopted by Metropolitan Planning Organizations (MPOs) and approved by the Department of Transportation. Instead, these projects, including urban street and nonoperational safety improvements, would be approved by a department district administrator. For communities without MPOs, department district administrators would also gain authority to approve smaller projects without Commission approval, intending to enhance local transportation efficiency.

SB 471: Generally revise vehicular traffic laws related to pedestrian crossings

SB 471 revises vehicular traffic laws to enhance pedestrian safety at crossings by creating the offense of "endangerment of pedestrians." It establishes a tiered system of fines for drivers who fail to yield the right-of-way to pedestrians, with higher penalties for violations occurring at crosswalks equipped with activated pedestrian-actuated devices. Drivers are also made liable for the cost of repairing or replacing any pedestrian-actuated devices they damage. Additionally, the bill clarifies driver responsibilities at flashing pedestrian-actuated devices, requiring them to yield and remain stopped until the pedestrian has crossed, or proceed with caution if unable to stop safely.

HB 739: Revise laws for agricultural vehicles on the highway

HB 739 revises traffic laws to improve safety when motor vehicles encounter agricultural vehicles on highways. The bill requires motor vehicle operators to reduce their speed when approaching an agricultural vehicle, either matching its speed if traveling in the same direction or reducing to half the posted limit if traveling in a different direction. It also mandates that agricultural vehicle operators move off the roadway or onto the shoulder when a line of vehicles forms behind them to allow other traffic to pass. These provisions directly affect anyone operating a motor vehicle or an agricultural vehicle on public roads.

HB 512: Require seat belts on newly purchased school buses

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.

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.
