An Act amending Title 75 (Vehicles) of the Pennsylvania Consolidated Statutes, in lighting equipment, further providing for use and display of illuminated signs.

HB 547 allows ride-hailing drivers (like Uber or Lyft drivers) to display approved illuminated signs inside their vehicles. The bill requires these signs to be submitted for review and approval by either the Pennsylvania Public Utility Commission or the Philadelphia Parking Authority within 15 business days. It prohibits these signs from using blue illumination or mimicking emergency vehicle lights. The law directly affects ride-hailing drivers and their service providers, creating a standardized approval process for in-vehicle signage.
