Relating to the definition of authorized emergency vehicle.

HB 245 amends Texas law to clarify and expand the definition of "authorized emergency vehicle" in the Transportation Code. The bill adds specific categories, including municipal/county emergency vehicles (like fire or police cars), ambulances operating under state licenses, volunteer firefighter vehicles during emergencies, industrial emergency response vehicles meeting historical safety standards, blood bank delivery vehicles, and federal law enforcement vehicles. These changes directly affect emergency service providers, municipalities, counties, and private responders by defining which vehicles qualify for emergency vehicle privileges like traffic exemptions. The bill takes effect January 1, 2026.
