HARRISBURG — Federal authorities have given Pennsylvania a few more months to comply with a 2005 federal law that requires people to prove they are legal U.S. residents in order for their driver’s licenses to be valid for federal purposes, Gov. Tom Wolf’s administration said Thursday. So, for now, Pennsylvania licenses will be sufficient proof of identification to get into federal facilities.

Wolf said the agreement would give state policymakers time to develop legislation to meet federal requirements. The new deadline is June 6.

Real ID provisions require certain identification standards in order to enter federal facilities such as military bases and nuclear plants, but next year more widespread problems loom, as the heightened standards will be required for people boarding commercial airliners.

The federal law was enacted as a result of the Sept. 11 terror attacks carried out by hijackers who had obtained valid ID from various states. The federal ID standards were designed to help prevent terrorism and fraud.

A 2012 state law, the Real ID Nonparticipation Act, is keeping Pennsylvania from meeting the federal law’s requirements. It passed the state Senate unanimously and the House by a wide margin. Concerns with the act included cost, constitutionality questions and government intrusiveness.
