Nebraska and Indiana will begin using the State-to-State Verification Service (S2S) Driver History Record (DHR) functionality on Monday, January 29, 2024. Tasks related to onboarding Nebraska and Indiana will be conducted during the weekend of January 27, 2024. During this process (Saturday evening to Monday morning), there may be periods during which the CDLIS/S2S Central Site is in inquiry-only mode or is unavailable (over and above the regularly scheduled maintenance window of 2:00 AM ET to 5:00 AM ET on Sunday, January 28, 2024). AAMVA is taking all steps possible to minimize service interruptions and will be sending alerts notifying states of Central Site availability throughout the process. Read more here.
