Motor vehicle inspectors

Who are we

The Connecticut Department of Motor Vehicles was founded in 1917. In 1919 the State Legislature authorized a uniformed force of 30 inspectors equipped with motorcycles to inspect and weigh trucks on both the New York and Massachusetts borders.

Connecticut pioneered the world’s first Point System to curb careless and dangerous drivers in 1947, and in 1950 Connecticut was the first to record vehicle engine numbers to track stolen vehicles.

Today, Motor Vehicle Inspectors are P.O.S.T. certified (Police Officers Standards and Training) law enforcement officers with powers of arrest. Each Inspector receives hundreds of hours of specialized training and utilizes the latest technologies to assist in DMV’s primary law enforcement functions which include:

  • Truck safety and size/weight enforcement
  • School bus inspections and enforcement
  • Licensing of repairers and dealers of new and used vehicles
  • Vehicle identification and auto theft investigation 
  • Registration enforcement
  • Speed and traffic law enforcement

The primary objective of the Connecticut Department of Motor Vehicles, Motor Carrier Safety Assistance Program (MCSAP) is to reduce the number of accidents and hazardous material incidents involving commercial motor vehicles. The Commercial Vehicle Safety Division operates from six fixed weight and inspections sites and patrols all highways and numerous secondary roads throughout the State.

DMV mission statement
To promote and advance public safety, security and service through the regulation of drivers, their motor vehicles, and vehicle-related businesses.

More about us

Connecticut DMV Inspectors proudly display this arm patch on their uniforms. The patch includes the State Seal, which became the uniform seal to be used by all departments in 1931 and included the motto “Qui Transtulit Sustinet” (meaning He Who Transplanted Still Sustains).

A popular explanation of the three grapevines is that they represent the three river towns (Hartford, Wethersfield, and Windsor) which were incorporated into the First Colony of Connecticut. It has also been noted that the three vines could represent the original three colonies of Connecticut (River Towns, Saybrook Colony and New Haven Colony).

Another interpretation of the three vines is that it represents the three fundamental principles on which Connecticut was founded -Religion, Education, and Law.

The banner attaching the United States flag and the State Flag reads, “Pride in Safety and Service.” Our mission is to promote and advance public Safety, Security, and Service through the regulation of drivers, their motor vehicles, and certain motor vehicle-related businesses.

Each Inspector is proud to serve the citizens of the State of Connecticut and will continue their duty in creating a safer highway environment for all.

  • What to expect
  • Weigh station reports

What to expect

The Department of Motor Vehicles Truck Squads patrol Connecticut’s highways looking for unsafe trucks, buses, hazardous materials vehicles, and their drivers.  The squads perform random safety checks and traffic enforcement on the highways and at the states six weigh stations. If you are stopped, you may be subject to a level 1 safety inspection, which is a detailed check of the driver, the vehicle, and its cargo.

When a Roadside Safety Inspection is done you are given a copy of the inspection report. You need to rectify any violations found, sign, and email the report to

Failure to return the form within 15 days of the inspection date may result in fines and/or suspension of the Vehicle(s) Registration.
Guidelines for the various types of inspections can be found on the Commercial Vehicle Safety Alliance website.

Inquire about a motor carrier's safety fitness information based on statistics provided by the State of Connecticut and the Federal Government.  Information is provided through the U.S. Department of Transportation at

Weigh station reports

Motor Vehicle Inspectors operate all five of Connecticut's weigh stations. Trucks and buses are required to stop to be weighed and inspected for any safety violations.  The weigh stations are located on the interstate highways in Danbury, Greenwich, Middletown, Union and Waterford.  Every six months, the DMV is required to report on activity at all five of Connecticut's weigh station.

Listed below are the six-month reports as required by CGS 14-270f.
