Starting a Trucking Company in Connecticut: The State-Level Steps
Updated September 2026
Your USDOT number and operating authority come from FMCSA and work the same in every state. What changes when you are based in Connecticut is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether Connecticut wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for Connecticut, checked against the state's own pages in September 2026.
In Connecticut apportioned plates come from the Connecticut Department of Motor Vehicles while the IFTA license comes from the Connecticut Department of Revenue Services. There is no separate Connecticut operating authority for general freight - the state layer is plates, fuel tax, the USDOT number and permits.
Interstate or Connecticut-only? Decide this first
Two different rulebooks apply depending on where the truck goes. Cross a state line for pay and you are an interstate carrier: FMCSA issues your USDOT number and operating authority (the $300 filing) and sets the insurance and BOC-3 rules, and Connecticut's job is plates, fuel tax and roadside enforcement. Stay inside Connecticut and you are an intrastate carrier: no federal authority is needed, and Connecticut's own rules take over - covered in the in-state section below.
Most new owner-operators run interstate, so this page assumes that unless it says otherwise. If you are truly Connecticut-only, you register the truck and its fuel with the state instead of IRP and IFTA, and the in-state section is the one to read closely.
Apportioned plates (IRP) in Connecticut
Connecticut's IRP office is the Connecticut Department of Motor Vehicles, IRP Unit (60 State Street, Room 102, Wethersfield). To base a fleet in Connecticut you have to show a real connection to the state: applicant must submit three different documents showing the same business name and Connecticut address (driver's license, Secretary of State filing, tax return, utility bill, property title, bank statement, etc.). New applications are dropped off at the IRP office or submitted through the CT IRP portal (dmvirp.ct.gov/ctenterprise); payment for new accounts and renewals must be guaranteed funds (certified check, bank check or money order); processing 7-10 business days; $150 per vehicle late renewal fee; the carrier's MCS-150 must be current. IRP Unit phone 860-263-5281.
Bring what every IRP office wants: your USDOT number and EIN, the truck's title or lease, proof of insurance, and a stamped Form 2290 Schedule 1 if the truck is 55,000 lbs or heavier. Fees are split among the states by the share of miles you run in each, so nobody can quote a flat price up front - the states that publish an estimate put a first-year 80,000 lb plate at roughly $1,250 to $2,500. You renew every year in the month Connecticut assigns you.
IFTA in Connecticut
IFTA lives at a different agency: the Connecticut Department of Revenue Services (DRS). Register and manage IFTA through myconneCT after registering as a Connecticut business; a valid USDOT number in good standing and an FEIN or SSN are required; DRS mails the license and decals.
Once licensed you file a quarterly return - due April 30, July 31, October 31 and January 31 - even for a quarter with zero miles. Keep every fuel receipt and your miles by state; the return is built from them. The license expires December 31 and is renewed every year.
Hauling only inside Connecticut
If the truck never leaves Connecticut you do not need federal operating authority (the $300 filing) - but Connecticut is one of the states that still wants in-state-only trucks to hold a USDOT number. Connecticut is on FMCSA's list. The CT DMV commercial registration page says a USDOT number 'is sometimes needed' (check FMCSA) and that federal inspection requirements apply to vehicles over 10,000 lbs in interstate commerce or over 18,000 lbs in intrastate commerce. The number is free, so get it early; almost every state form asks for it.
Connecticut has no state operating authority for general freight. A truck that never leaves Connecticut registers through the DMV's commercial process (form H-13B, proof of insurance and ownership, fees by GVWR) instead of IRP, gets its USDOT number, and registers for the Highway Use Fee once it is 26,000 lbs or heavier.
UCR when you are based in Connecticut
Connecticut takes part in the Unified Carrier Registration program. Interstate carriers register once a year at ucr.gov - $46 for 0-2 trucks in 2026, $55 in 2027. Carriers that only haul inside the state do not register for UCR at all.
Other Connecticut permits and programs
Oversize and overweight permits come from the Connecticut Department of Transportation, Bureau of Highway Operations - Oversize/Overweight Permit Office (CVO WebPortal cvoportal.ct.gov, 860-594-2560) - every state wants its own permit for a load beyond the legal size or weight, and most now sell them online.
Other Connecticut-specific things a new one-truck carrier runs into:
- Connecticut Highway Use Fee (HUF): Since January 1, 2023, anyone operating a Class 8-13 vehicle of 26,000 lbs or more gross weight on Connecticut highways must register for the Highway Use Fee in myconneCT and file quarterly (since Oct 2023); the per-mile rate runs from 2.5 cents (26,000-28,000 lbs) to 17.5 cents (over 80,000 lbs).
Who checks on you in Connecticut
Roadside inspections in Connecticut are run by the Connecticut Department of Motor Vehicles, Commercial Vehicle Safety Division (MCSAP; six fixed weigh/inspection sites), working with FMCSA. Expect the New Entrant safety audit within your first 12 months of interstate operation - the walkthrough's audit checklist covers the 16 things that fail it automatically.
The order to do it in
- Form the business and get a free EIN from the IRS.
- Get your USDOT number (free) through FMCSA's Motus system - and apply for operating authority ($300) if you will ever cross a state line.
- Have your insurer file the federal proof of insurance and hire a process agent for the BOC-3.
- File Form 2290 with the IRS if the truck is 55,000 lbs or heavier and keep the stamped Schedule 1 - the plate office asks for it.
- Get apportioned plates from the Connecticut Department of Motor Vehicles (or Connecticut commercial plates if the truck will never leave the state).
- Get your IFTA license and decals from the Connecticut Department of Revenue Services.
- Register for UCR at ucr.gov if you run interstate.
- Put the deadlines in the Stay Legal calendar: MCS-150 update, IFTA quarters, UCR, Form 2290, medical card, annual inspection.
Always confirm with Connecticut
Fees and forms move without notice. Before you pay anyone, open the official pages below and check the current figures - it takes ten minutes and prevents expensive surprises. HaulLegal is not the government, is not a law firm, and never files anything for you; you do every step yourself.
Official Connecticut pages
Based in Connecticut? The walkthrough puts all of this in order.
The HaulLegal walkthrough lays out every step from the business filing to your first safety audit, federal and state, with the real government fee beside each one - and the Stay Legal calendar turns your USDOT number and dates into a deadline list that emails you before each one. The first four steps are free, no signup.
One thing every Connecticut carrier needs no matter which state they are based in: a self-employed CDL driver has to be in a drug and alcohol random testing pool run by a consortium before the first mile, and having no program and no random pool are two of the sixteen automatic failures on the New Entrant safety audit.
