The Idaho Transportation Department will hold public hearings next week to take comments on allowing trucks up to 129,000 pounds on U.S. Highway 95 and sections of state Highways 3 and 8 in Latah County.
The law affects trucks with reducible shipments, which means cargo or goods can be removed to make them lighter, said Adam Rush, Idaho Transportation Department public involvement coordinator.
The maximum reducible load has been 105,000 pounds, 12 tons per truck less than the new rules.
"It's really designed to help trucking and shipping companies improve their efficiency and reduce the number of vehicles on the road, which reduces congestion and improves safety," Rush said.
He added that each truck would be able to haul more cargo, thus reducing the number of trips trucks would have to make.
