Vermont will begin using State-to-State (S2S) Verification Service and S2S Driver History Record (DHR) functionality from Monday, November 10, 2025. Tasks related to onboarding Vermont will be conducted during the weekend of November 8, 2025. During this process (Saturday evening to Monday morning), there will be periods during which the CDLIS/S2S Central Site (Central Site) will be in inquiry-only mode or unavailable (over and above the regularly scheduled maintenance window of 2:00 AM ET to 5:00 AM ET on Sunday, November 9, 2025). AAMVA is taking all steps to minimize service interruptions and will be sending alerts notifying states of Central Site availability. Read more here.
