This bill amends Idaho's traffic laws to enhance regulations regarding vehicle operation on multilane highways. Specifically, it introduces new provisions that require vehicles to be driven in the right-hand lane on multilane highways, with exceptions for overtaking, preparing for a left turn, or when right-hand lanes are obstructed. Additionally, it stipulates that vehicles in the left-hand lane must not impede others traveling behind them and must not drive slower than vehicles in the right-hand lanes. A violation of these new rules will be classified as an infraction, punishable by a $75 fine.

Furthermore, the bill amends existing laws to clarify minimum speed regulations, stating that no vehicle should operate at a speed that impedes normal traffic flow, particularly in the left-hand lane of controlled-access highways. The Idaho Transportation Department is tasked with placing signs on multilane highways to inform motorists of these new provisions. The bill declares an emergency, making it effective from July 1, 2026.
