What Trucking Insurance Requirements Apply in Connecticut?

Connecticut requires a motor carrier to report insurance to DMV annually when a vehicle used only in Connecticut has a gross or combination weight rating of at least 18,001 pounds; lower-threshold and other vehicles use a DMV affidavit for registration transactions. Interstate reporting begins at 10,001 pounds, so an in-state fleet should use its actual operating scope rather than copy an interstate filing checklist.

What Is Trucking Insurance?

Trucking coverage can address liability, damage to your trucks and cargo losses, but one quote may not include all three. If you haul goods for customers or yourself, compare those protections and check whether the quote needs motor-carrier or other commercial auto coverage. Read the national Trucking guide.

Connecticut Trucking Insurance Requirements

Requirement	Details
Annual DMV insurance report	Intrastate vehicles at 18,001 lb or more; 10,001 lb for interstate vehicles; also placarded hazmat and passenger-capacity triggers ¹
Other commercial-vehicle registration	If none of the annual-report criteria apply, submit DMV's insurance affidavit for new registration or renewal ¹

What Should You Watch for With Trucking Insurance in Connecticut?

Use The Connecticut-Only Weight Threshold
DMV's annual-report trigger for intrastate commerce is 18,001 pounds, while the interstate trigger is 10,001 pounds. Check gross vehicle, truck/trailer, and combination ratings across your routes; a local fleet may use the different state threshold even when its vehicle resembles an interstate truck. ¹
File The Report Or The Registration Affidavit
If any listed annual-report trigger applies, Connecticut DMV asks the carrier to report insurance coverage once each year. If none applies, the agency instead requires its affidavit for new-registration or renewal transactions; ask which vehicle records the insurer will report. ¹
Check Nonweight Reporting Triggers
DMV also requires annual reporting for vehicles designed for more than 15 passengers and for loads requiring hazardous-material placarding, regardless of the intrastate 18,001-pound threshold. Tell the agent about seat capacity and the exact placard status before deciding an affidavit is sufficient. ¹
Keep Household-Mover Authority Separate
CTDOT's Regulatory and Compliance Unit publishes a separate new Household Goods Carrier Certificate application. If you move household goods for compensation within Connecticut, confirm the required carrier certificate and its insurance filing with CTDOT as well as the DMV vehicle report. ^2,³

Which Trucking Insurance Providers Have Connecticut License Records?

No provider in our research has both a state license record and a listing for this coverage line. This does not establish that providers are unlicensed. Check the regulator’s license lookup and confirm availability with a provider when requesting a quote.

Surplus-Lines Tax and Stamping Office in Connecticut

Reported tax rate. 4% of gross premium when Connecticut is the home state ^7,^8,⁹

When Connecticut is the insured’s home state, surplus-lines tax is 4% of gross premium; certain state and local government insureds are exempt, and broker or policy fees are not part of the premium-tax base. Connecticut’s required notice says these policies are outside the state guaranty association. Most placements require three declinations or an export-list qualification; an exempt commercial purchaser may qualify for the federal § 8205 search exception after disclosure and a written request.

What Should You Ask Before Buying Trucking Insurance in Connecticut?

Do our Connecticut-only trucks meet the 18,001-pound intrastate annual-report threshold, or does another trigger apply?
Who will report coverage annually to DMV, and which units fall under an affidavit at registration or renewal?
Does any load require placarding, or does any vehicle seat more than 15, which would trigger annual reporting regardless of truck weight?
Do our household-goods routes require a CTDOT certificate and a separate insurance filing beyond the DMV report?

Trucking Insurance in Connecticut: Frequently Asked Questions

When must a Connecticut intrastate carrier report truck insurance to DMV?

What if my Connecticut commercial truck is below the annual insurance-report threshold?

If none of DMV's listed weight, passenger, or hazmat criteria apply, the agency requires an insurance affidavit for a new registration or renewal transaction. ¹
