The bill proposes revisions to speed limit laws in Montana, specifically increasing the daytime and nighttime speed limits on national highways that have been expanded to four lanes. The new legal language specifies that the speed limit on these highways, which are not subject to a permanent special speed zone, will be set at 75 miles an hour during the daytime and 70 miles an hour during the nighttime. Additionally, the bill amends existing sections of the law to clarify the definitions of "daytime" and "nighttime" and outlines the conditions under which speed limits may be altered by the transportation commission or local authorities. Furthermore, the bill modifies penalties for speed limit violations. It includes an addition of section (1)(c) to the penalty structure, which allows for fines based on the new speed limits. The legislation also maintains that violations of speed limits under certain conditions may not be recorded against a driver's record, provided the excess speed does not exceed specified thresholds. However, it stipulates that exceeding 90 miles an hour in violation of the speed limit may result in a recorded offense. Overall, the bill aims to modernize speed limit regulations while ensuring safety on expanded highways.
