The Arizona Senate’s Committee of the Whole advanced Senate Bill 13-32 on March 16, 2026, after adopting amendments that narrow its funding language and delay any construction until a state-directed study is completed. The committee voted to report the bill as amended and returned it to the full Senate calendar.
Sen. Kubey raised a substantive objection during floor consideration, saying the proposal ‘‘really, really does aim to advance autonomous vehicles in lieu of rail’’ and warned it favors short-term economic assessments over long-term benefits of light rail. He argued that decisions about transit priorities are best made by local municipal authorities and regional agencies such as Valley Metro rather than the state legislature.
Sponsor and amendment proponents said the Kavanaugh floor amendment removed a direct funding reference and the prohibition on construction until the study is done, while preserving a mechanism for the state to undertake the requested analysis. Sen. Kavanaugh explained that the amendment is intended to shape a study that could guide future decisions and to enable negotiation with the governor’s office on study scope.
The committee’s adoption of the ATT (Appropriations, Transportation and Technology) amendment and the floor amendment led to a do-pass recommendation. No final third-reading floor vote on SB 13-32 is recorded in the transcript for March 16; the committee report was adopted and the bill was placed back on the calendar for subsequent action.
Why it matters: SB 13-32 would direct state participation in light-rail expansion studies and could affect how long-range transit planning and funding responsibilities are allocated between state and local governments. Supporters say a study can inform policy; critics say it risks state intrusion into locally managed transit systems and could bias analysis toward emerging vehicle technologies.
Next steps: The committee reported SB 13-32 as amended; the bill remains on the Senate calendar for future consideration and potential third reading.
