AAMVA congratulates Oregon on successfully implementing State-to-State Verification Service (S2S) Driver History Record (DHR) and the Medical Examiner Certification Integration Final Rule (NRII) solution on May 11, 2025. All migration activities have completed on schedule, and CDLIS/S2S services are fully operational now. Oregon will henceforth be 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 12, 2025, Arkansas and Oregon 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.
