MOTOR VEHICLES – Amends existing law to provide that speed limits for vehicles with five or more axles operating at a gross weight of more than 26,000 pounds shall be the same as for other vehicles.
H 664 would remove a lower speed limit for large trucks in Idaho. Currently, trucks with five or more axles and a gross weight over 26,000 pounds must travel 10 miles per hour slower than other vehicles on most roads. The bill changes the law so these trucks can travel at the same speed limits as passenger cars and smaller trucks, without the 10 mph reduction. This change would take effect on July 1, 2026.
