Chamber Passed·3/9/26

Idaho S1340 amends traffic laws to mandate driving in the right lane on multilane highways and penalizes left-lane driving that impedes traffic.

Idaho S1340 amends existing law to require drivers to use the right-hand lane on multilane highways unless passing. It also imposes penalties for driving in the left-hand lane of a controlled access highway and impeding the flow of traffic. The bill mandates that vehicles must not impede other vehicles traveling in the same lane and behind them. Violations of these provisions are punishable by a fine of seventy-five dollars. The Idaho transportation department is directed to place signs on multilane highways to inform motorists of these changes.
