AAMVA congratulates Pennsylvania on successfully implementing the State-to-State Verification Service (S2S) Driver History Record (DHR) and New Mexico, Pennsylvania, and Virginia on successfully implementing the Medical Examiner Certification Integration Final Rule (NRII) solution on May 4, 2025. All migration activities have completed on schedule, and CDLIS/S2S services are fully operational now. Pennsylvania is now able to use S2S DHR to perform their Driver History maintenance related functions. This supports the goal of limiting any person to only one driver’s license and one driver history. Starting May 5, 2025, New Mexico, Pennsylvania, and Virginia will begin receiving medical certification information electronically from the National Registry. These states are now able to inquire the National Registry for a driver's medical certification information. Read more here.
