The Connecticut CVISN/PRISM Project

***Holiday Closing***:  On Friday, February 9, DMV offices will close at 12:30 p.m. to observe the President Washington's Birthday holiday, and remain closed on Saturday, February 10.  Offices will reopen on Tuesday, February 13, at 7:45 a.m.


The Commercial Vehicle Information Systems and Networks/ Performance and Registration Information Systems Management (CVISN/PRISM) Project combines two federal-state initiatives that use Intelligent Transportation Systems technology to promote the safe and legal movement of commercial vehicle traffic within our state and across the nation. Both initiatives seek to improve highway safety by rewarding safe motor carriers, penalizing unsafe carriers and removing unsafe commercial vehicles from the roadways.


PRISM and CVISN share key concepts:

  • Focus safety enforcement on high risk operators
  • Use open standards for data communications
  • Use standardized algorithm for determining a carrier’s safety fitness
  • Use data exchange systems that conform to the National Intelligent Transportation Systems (ITS) Architecture

These concepts, implemented through state and national systems, link CVISN deployment and PRISM Program activities. Because the CVISN and PRISM Projects are closely related, in Connecticut they are considered a single combined Project, the CVISN/PRISM Project.

CVISN - Commercial Vehicle Information Systems and Networks

The CVISN program refers to the collection of information and communication systems owned and operated by the Federal Highway Administration, states, motor carriers and other stakeholders. The CVISN program organizes these commercial vehicle operations (CVO) related systems, allowing them to operate in an integrated manner.

CVISN is a cooperative effort among the following agencies:

  • Connecticut Department of Information Technology
  • Connecticut Department of Motor Vehicles
  • Connecticut Department of Emergency Services and Public Protection 
  • Connecticut Department of Revenue Services
  • Connecticut Department of Transportation
  • Federal Motor Carrier Safety Administration
  • Motor Transport Association of Connecticut, Inc.

See more information on the federal CVISN program on the Federal Motor Carrier Safety Administration website.

PRISM - Performance and Registration Information Systems Management


The PRISM program links interstate commercial motor vehicle registrations to the safety fitness of motor carriers. The program includes two major processes--the Commercial Vehicle Registration Process, and the Motor Carrier Safety Improvement Process (MCSIP) that work in parallel to identify motor carriers and hold them responsible for the safety of their operation. The performance of unsafe carriers is improved through a comprehensive system of identification, education, awareness, safety monitoring and treatment.

The PRISM program in Connecticut is run by the Department of Motor Vehicles.
