SB 184 Wisconsin Senate · 2025-2026 Regular Session

Relating to: governmental restrictions based on the energy source of a motor vehicle or other device.

SB 184 would prevent Wisconsin state agencies and local governments from restricting the use or sale of motor vehicles or other devices based on their energy source (such as gasoline, electricity, or hydrogen). It specifically prohibits rules that ban or limit vehicles/devices due to their power source, though government fleets may still select energy types for their own purchases. The law would apply to all state and local regulations, including those governing vehicle access, sales, or device usage. This bill aimed to remove barriers for alternative-energy vehicles in public policy contexts.
