This bill amends Montana's speed limit laws by increasing the speed limits for vehicles traveling on national highways that have been expanded to four lanes. Specifically, it establishes a new speed limit of 75 miles an hour during the daytime and 70 miles an hour during the nighttime for these highways, provided they are not subject to a permanent special speed zone. The bill also maintains existing speed limits for interstate highways and other public highways, while clarifying definitions for "daytime" and "nighttime" driving. Additionally, the bill modifies the penalties associated with speed limit violations. It includes an amendment to specify that violations of the new speed limit for expanded national highways will be treated similarly to other speed limit violations, with fines structured based on the amount by which the speed limit is exceeded. Importantly, the bill stipulates that certain minor violations will not be recorded against a driver's record, provided they do not exceed specified thresholds, thus offering leniency for drivers who slightly exceed the speed limits.
