Commercial auto, Connecticut (annual)

Insureon average for Connecticut small-business customers, updated March 2026

Insureon reports that its Connecticut small-business customers pay an average of $290 a month, or $3,480 a year, for commercial auto, based on policy data updated March 19, 2026. Most of those customers have fewer than five employees and five years or less in business, so the figure mostly reflects pickups, vans and cars. A one-van service business near the state floor can pay well under it, while a freight truck of 10,001 pounds or more that needs the $750,000 limit the DMV lists, or a passenger van that needs $1.5 million, will pay far more.

What moves your price

  • The town where each vehicle is garaged and how far it runs
  • Vehicle type and weight, especially above the 10,001 and 18,001 pound thresholds the DMV uses
  • Liability limits above 25/50/25, and the UM/UIM limit, which by default matches your bodily injury limit
  • Whether vehicles cross into New York, Massachusetts or Rhode Island on interstate work
  • Each driver’s record and experience with the vehicle class
  • Your claims history and any reported lapse in coverage

Connecticut

What’s different in Connecticut

25/50/25 is the floor, with UM/UIM to match

Every registered vehicle needs at least $25,000 per person and $50,000 per accident for bodily injury and $25,000 for property damage, plus uninsured and underinsured motorist cover of at least 25/50. The standard UM/UIM amount equals your bodily injury limit, and you may buy up to double it (C.G.S. 38a-336).

An uninsured commercial vehicle can be a felony

Under C.G.S. 14-213b, operating or allowing operation of an uninsured vehicle brings a fine of $100 to $1,000. An owner of a commercially registered vehicle who knowingly runs it uninsured commits a class D felony, punishable by up to $5,000, up to five years in prison or both.

Insurers report cancellations to the DMV every month

Under C.G.S. 38a-343, insurers notify the DMV of cancelled policies monthly, and the DMV then issues a suspension notice. The DMV lets you pay a $200 fine under a consent agreement to resolve a lapse, and a registration stays blocked from renewal until compliance issues are cleared.

A suspended registration can cost you the truck

Police may seize the plates and impound an uninsured vehicle with a suspended registration, whether it is driven or parked, under C.G.S. 14-12h. The owner gets it back only with a valid registration and current insurance card, and a vehicle held more than 45 days may be forfeited to the state.

Trucks over 18,000 pounds need a DOT number in-state

The DMV requires an intrastate DOT number for vehicles of 18,001 pounds or more in Connecticut commerce, for placarded hazmat and for passenger vehicles above set seat counts. Interstate work drops the weight threshold to 10,001 pounds, and C.G.S. 14-163c applies the federal safety rules to both.

Heavier vehicles report insurance to the DMV every year

Carriers in those classes must send an ACORD certificate of liability insurance to the DMV Compliance Unit once a year. Other commercial vehicle owners file a DMV affidavit at registration and renewal instead.

Coverage

Coverage Connecticut businesses need

Commercial auto liability

Pays for injuries and damage your vehicles cause to others. The state floor is 25/50/25, but the DMV lists $750,000 for freight vehicles of 10,001 pounds or more, and contracts often set their own higher limits.

How commercial auto works →

Uninsured and underinsured motorist

Required on every Connecticut auto liability policy at 25/50 or more. It pays for injuries to your driver and passengers when the at-fault driver has no insurance, too little or flees.

How commercial auto works →

Physical damage

Collision and comprehensive for your own vans and trucks. The state does not require it, but lenders and lessors usually do, and liability never pays to fix your vehicle.

How commercial auto works →

Hired and non-owned auto

Covers your business when employees use their own cars for errands or you rent a vehicle. It is liability only and does not repair the car being driven.

How commercial auto works →

Umbrella or excess

Adds limits above your auto policy when a contract or a heavy vehicle calls for more than your primary limit allows.

How umbrella / excess works →

Motor truck cargo

Pays for damage to freight you haul for others. Auto liability does not cover the load in your truck.

Pay less

How to lower the cost

  • Keep coverage continuous: a reported lapse can mean a $200 DMV fine and a registration you cannot renew until it is cleared.
  • When you switch insurers, mail the new declarations page to the DMV Insurance Compliance Unit so the old insurer’s cancellation notice does not become a warning letter.
  • Check each driver’s motor vehicle record before hiring and every year after.
  • Use hired and non-owned auto cover for occasional employee errands instead of adding vehicles you rarely use.
  • Raise physical damage deductibles on older vans and trucks you could afford to repair.
  • Compare quotes at renewal; Florin is an independent broker that compares options from several insurers.

Common questions

Commercial auto insurance in Connecticut: questions

How much does commercial auto insurance cost in Connecticut?

Insureon reports an average of $290 a month, or $3,480 a year, for its Connecticut small-business customers as of March 2026. Heavy trucks, passenger vans and businesses with claims or lapses pay more.

What happens if my business policy lapses in Connecticut?

Your insurer reports the cancellation to the DMV, which sends a warning or suspension notice. You can usually resolve it by showing current coverage and paying a $200 fine; ignoring a registration suspension for 30 days can put the owner’s driver’s license at risk.

Do I need a USDOT number for in-state trucking in Connecticut?

Yes, if the vehicle is 18,001 pounds or more, carries placarded hazmat or carries more than 8 passengers for pay, per the DMV. Interstate operations need one from 10,001 pounds.

How much liability does a Connecticut truck need?

The DMV lists $750,000 for non-hazardous freight vehicles of 10,001 pounds or more GVWR and $1 million or $5 million for hazardous materials. Lighter vehicles need the 25/50/25 floor unless a contract asks for more.

How much uninsured motorist cover do I need in Connecticut?

At least 25/50. Under C.G.S. 38a-336 the standard amount equals your bodily injury liability limit, and you can buy up to double that amount.

I changed insurers and got a DMV warning letter. What do I do?

The DMV says a change of insurer can trigger a notice from the old company. Mail a copy of your new declarations page or permanent insurance card to the DMV Insurance Compliance Unit.

Can a business be charged for an employee driving an uninsured company vehicle?

Yes. C.G.S. 14-213b bars owners from permitting operation without the required insurance, and doing so knowingly with a commercially registered vehicle is a class D felony.
