Bill > H0664

This bill amends existing Idaho law regarding vehicle speed limits to ensure that large trucks with five or more axles, weighing over 26,000 pounds, will have the same maximum speed limits as other vehicles on interstate highways, in urban and non-urban areas, and on state highways. Previously, these heavier vehicles had a different, generally lower, speed limit, with specific restrictions in urban areas. The bill removes these distinctions, meaning these large trucks will now be subject to the same posted speed limits as passenger cars and lighter trucks. This change is intended to standardize speed limits for all vehicles, regardless of their size or weight, and will take effect on July 1, 2026.
