Pennsylvania is the largest of nine states to not comply with federal Real ID law for driver’s licenses

Eleven passenger and cargo airlines have implored the Pennsylvania legislature to comply with a federal Department of Homeland Security Real ID law that requires states to change driver’s licenses to reduce counterfeiting.

Pennsylvania is the largest state that has not complied with the law, passed by Congress after the 2001 terror attacks. Other noncompliant states are Oklahoma, Minnesota, Washington, Maine, Kentucky, Missouri, South Carolina, and Montana.
