Idaho Senate Committee Advances Bill to Equalize Truck and Car Speed Limits

Key Details Idaho House Bill 664 would eliminate differential speed limits for commercial vehicles, allowing trucks to travel at the same speeds as passenger cars on state roadways. The measure advanced through the Senate Committee on March 12th and now heads to the full Idaho Senate for a final vote. Why It Matters Proponents argue that uniform speed limits could reduce traffic congestion and improve flow by eliminating the speed differential between vehicles. Sen. Josh Kohl cited safety concerns, noting he has witnessed numerous close calls and pileups caused by large speed gaps between trucks and cars. What We Know Rep. Pickett, who sponsored the bill, clarified it doesn't mandate uniform speeds but removes the state mandate preventing trucks from traveling at posted limits. Trucks with speed limiters would still operate between 65-70 mph in most cases. The Debate Opponents raise safety concerns about heavy trucks, which can weigh up to 129,000 pounds, potentially traveling at higher speeds. Sen. Alison Rabe expressed worry about trucks going up to 75 mph in some areas. Research cited by the committee shows mixed results - some studies indicate uniform limits reduce passing crashes, while others show no difference in crash rates. Next Steps The bill will proceed to the full Idaho Senate for final consideration.
