Bill > SB433

This bill revises Montana's traffic laws regarding roundabouts and rotary traffic islands, establishing clear rules for right-of-way and vehicle movement. The legislation defines a roundabout as a circular intersection and provides specific guidelines for how vehicles should navigate these traffic features. Vehicles passing around a roundabout must travel only to the right of the island or center, and they have the right-of-way over approaching vehicles. Vehicles approaching a roundabout must yield to vehicles already circulating within it. The bill also introduces special provisions for towing vehicles, allowing them to deviate from their lane when approaching a roundabout with due regard for other traffic, and establishes a priority rule where if two towing vehicles are simultaneously entering a roundabout, the vehicle on the left has the right-of-way. The bill modifies existing state traffic laws to clarify these rules, removing some previous language about turn signals and hazard signals, and providing more precise definitions and expectations for drivers navigating roundabouts. These changes aim to improve traffic flow and safety at circular intersections by creating more standardized and predictable driving behaviors.
