WETHERSFIELD, Conn. (AP) - Connecticut's Department of Motor Vehicles is dropping the private vendor it has used to help overhaul the agency's computer system.

DMV spokesman William Seymour said Friday the agency notified 3M it is exercising a contract option and won't proceed with the third phase of the project.

The DMV is still exploring options for the third phase, which involves modernizing the licensing system. Seymour said the DMV is still holding 3M accountable for fixing bugs in the current system, which involved modernizing vehicle registrations.

A 3M spokesman says the St. Paul, Minnesota-based company values its relationship with Connecticut and remains committed to meeting its obligations to DMV.

The DMV has been plagued by long wait times, erroneous vehicle registration cancelations and other problems since the upgrade was launched last summer.
