A Puerto Rico license plate, the subject of a House investigation into the single plate system. New Progressive Party Rep. Gabriel Rodríguez-Aguiló has introduced House Bill 459, directing the House Transportation and Infrastructure Committee to investigate Puerto Rico’s single license plate system. The system stems from Act 22 of 2000, the Puerto Rico Vehicle and Transit Act, amended by Act 2 of 2016 and Act 23 of 2020. Act 2 of 2016 established the model under which a license plate belongs to the vehicle’s owner, not the vehicle itself. Supporters say a functioning single license plate system could reduce costs for drivers and update Puerto Rico’s transportation framework.
