RULES OF THE ROAD – Amends existing law to require drivers to drive in the right-hand lane on multilane highways unless passing and to provide penalties for driving in the left-hand lane of a controlled access highway and impeding the flow of traffic.
S1340A amends Idaho’s traffic laws to require drivers on multilane highways to travel in the right-hand lane unless they are actively passing another vehicle. It also adds penalties for driving in the left-hand lane on a controlled-access highway in a way that impedes traffic flow. In practical terms, the bill is aimed at limiting prolonged left-lane travel and reinforcing the expectation that the left lane is for passing rather than cruising.
The bill would change the state’s rules of the road by creating a clearer legal duty for drivers to keep right except when overtaking, and by authorizing enforcement against left-lane obstruction on controlled-access highways. It would affect motorists on highways with multiple lanes, law enforcement officers responsible for traffic enforcement, and courts handling citations or penalties under the amended statute. The measure is framed as a traffic-management and roadway-safety provision rather than a broad transportation overhaul.
The bill would modify Idaho traffic code to establish a right-lane travel requirement on multilane highways and to create or strengthen penalties for left-lane driving that impedes traffic on controlled-access highways. This would give law enforcement and prosecutors a clearer statutory basis to cite drivers who remain in the passing lane without passing, and it could influence driver behavior on interstates and other high-volume roadways. The affected parties are everyday motorists, commercial drivers, and enforcement agencies, with the practical effect of shifting lane-use expectations and potentially increasing citations for left-lane obstruction.
Based on the available context, the bill appears to have been introduced with a straightforward public-safety and traffic-flow rationale and without recorded committee debate or roll-call votes in the provided materials. The caption and sponsor list suggest support from its sponsors for a conventional traffic enforcement approach. However, the bill’s last action indicates it was returned from the House failed, which suggests it did not secure enough support to advance, even though no detailed objections are included in the record provided.
The main point of contention is likely the enforcement of a mandatory keep-right rule and whether penalizing left-lane travel goes too far in regulating ordinary driving behavior. Potential concerns may include how officers would determine when a driver is truly impeding traffic, whether the rule could be applied inconsistently, and whether it could create confusion for drivers in heavy traffic or near exits. The available record does not include committee testimony or votes, so the specific arguments for or against the bill are not documented here, but the House failure indicates the measure faced enough resistance to stop its progress.
