Relating to rail fixed guideway public transportation system.

This bill clarifies that rail fixed guideway public transportation systems (like light rail or streetcar systems operated by mass transit districts) are not considered "commercial motor vehicles" under Oregon law. It amends the Oregon Vehicle Code to explicitly exclude these systems from regulations that apply to commercial trucks, buses, or hazardous materials transport. This directly affects Oregon's mass transit districts (e.g., TriMet) operating rail systems by removing unnecessary commercial vehicle compliance requirements. The change ensures rail transit systems are regulated under transportation-specific rules, not commercial vehicle standards.
