transportation excise tax; election authority

HB 2566 creates a new transportation excise tax in Arizona counties with over 3 million residents, effective after 2025. The tax applies to business transactions, retail electricity/gas use, and utilities at rates tied to existing tax brackets, generating revenue for transportation projects. Funds must be distributed as follows: 40.5% to state highway maintenance, 22.5% to arterial roads, and 37% to public transit (including light rail rehabilitation, capped at 3.5%). The tax expires after 20 years unless voters approve an extension, and it prohibits using funds for rail extensions or reducing highway lanes without specific safety and public input requirements.
