Upgrades Made to Automotive Management Application

Beginning on June 2, 2025, users of our current Automotive Delivery & Information Management (ADIMS) will be upgraded to the new Automotive Carrier System (ACS). The new ACS platform allows for efficient management of finished automobiles by Vehicle Identification Number (VIN) on our network.
