This bill proposes changes to Minnesota transportation laws regarding the installation of J-turn intersections. The key provisions of the bill include:

1. Definition of J-turns: The bill formally defines a J-turn as an intersection design that eliminates direct left turns and through movements from minor cross streets. Instead, vehicles from the minor road must first turn right, then make a U-turn at a designated location to continue in their intended direction.

2. Municipal Consent Requirement: The bill mandates that municipal governments must provide consent before any J-turn can be installed within their jurisdiction. This alters the current process by requiring local government approval for such highway adjustments.

3. Projects Requiring Review: The bill specifies that projects involving J-turn installation will be subject to the same review processes as other highway modifications that affect traffic capacity, access, or require land acquisition.

4. Exclusion from Safety Measures: The bill explicitly states that J-turns are not classified as traffic safety measures, distinguishing them from other traffic control devices or safety-related installations that the state transportation commissioner has the authority to implement without municipal approval.

Overall, the bill seeks to give local municipalities more control over J-turn installations by requiring their consent before implementation.
