Revise right-of-way laws for roundabouts
SB 433 revises right-of-way laws for drivers navigating roundabouts in Montana. It establishes that vehicles already in a roundabout have the right-of-way over those approaching it, which must yield. The bill creates specific provisions for towing vehicles, allowing them to deviate lanes for safe passage and requiring other drivers to yield and not pass them within or approaching a roundabout. If two towing vehicles enter a roundabout simultaneously, the vehicle to the left is granted the right-of-way.
