HD 4150 Massachusetts House · 194th Legislature (2025-2026)

An Act relative to providing multimodal transportation technologies

This bill establishes rules for operating fully autonomous vehicles (without human drivers) on Massachusetts roads. It requires these vehicles to obtain a special license from the Massachusetts Department of Transportation, achieve a "minimal risk condition" if the system fails, and include a human driver for vehicles over 10,000 pounds. Operators must submit law-enforcement interaction plans detailing crash response and vehicle monitoring, and maintain proof of insurance. The bill directly affects autonomous vehicle manufacturers, fleet operators, and MassDOT, which gains authority to issue licenses and enforce safety standards under the new framework.
