Connecticut Car Insurance Requirements — and Why the State Minimum Is Not Enough

What Connecticut Actually Requires

Before a private passenger vehicle can be registered and driven in Connecticut, it has to carry a short list of compulsory coverages. Those limits are a legal floor, not a planning target, and the Connecticut Insurance Department says so in its own consumer guidance: the minimum limits may not be enough to provide sufficient financial protection.

As of this writing, the compulsory limits are:

• Bodily injury liability: $25,000 per person and $50,000 per accident
• Property damage liability: $25,000 per accident
• Uninsured and underinsured motorist bodily injury: at least $25,000 per person and $50,000 per accident

You will usually see this written as 25/50/25. The first number is the most the policy will pay for injuries to any one person. The second is the most it will pay for all injuries arising from a single accident, no matter how many people were hurt. The third is the most it will pay for damage to other people's property. Requirements are revisited by the legislature from time to time, so confirm the current numbers with the Connecticut Insurance Department or your carrier before relying on them.

Two things deserve immediate attention. First, none of these coverages pay for your own vehicle or your own injuries in a crash you caused; collision and comprehensive are optional under state law, though a lender or lessor will require them by contract. Second, Connecticut is an at-fault state. No-fault was repealed effective January 1, 1994, so an injured party pursues the at-fault driver for their losses rather than collecting a fixed first-party benefit.

Bodily Injury and Property Damage Solve Two Different Problems

Bodily injury liability responds when you injure someone else. It funds their medical treatment, lost income, future care and general damages, and it pays for your legal defense. Under most personal auto policies, defense costs are paid in addition to the limit rather than eroding it, but that only helps while the limit is standing. Once it is exhausted by settlement or judgment, the carrier's obligation is generally satisfied.

Property damage liability is the one most people underestimate. A modern SUV, an electric vehicle with a damaged battery pack, or a vehicle written off entirely can consume a $25,000 limit without difficulty. So can a municipal claim for a guardrail and utility pole, or a storefront that has to close while it is repaired.

Why the Minimum Is a Poor Fit for a Household With Assets

When a claim exceeds the policy limit, the policy stops. The claimant does not. In an at-fault state, the difference between what a settlement or verdict says the injury is worth and what your policy will pay is your personal responsibility, collected from what you own and from what you will earn.

That is why identical limits mean entirely different things to different households. For a family with taxable investment accounts, meaningful home equity, or two professionals with decades of earning ahead of them, a shortfall is a real and collectible number. Future earnings are often the most valuable asset such a household owns, and an unsatisfied judgment reaches them.

The per-accident limit makes this worse than it first appears. A $50,000 per-accident bodily injury limit is not $50,000 for the person you injured. It is $50,000 shared among everyone injured in that accident. One vehicle carrying a driver and three passengers, struck in stop-and-go traffic on I-95, can exhaust the state minimum before the first serious injury is fully valued. Households commuting from Fairfield and the shoreline towns spend a great deal of time in that traffic.

The right question is not what the state requires, but what a serious claim could cost and what happens to the household if it exceeds the limit.

Uninsured and Underinsured Motorist: The Coverage That Most Often Decides a Serious Claim

Liability coverage protects other people from you. Uninsured and underinsured motorist coverage, usually shortened to UM/UIM, protects your family from everyone else. When someone in your household is seriously hurt by another driver, the recovery is capped by that driver's insurance. If the at-fault driver has no coverage, cannot be identified, or carries exactly the state minimum, your own UM/UIM becomes the only meaningful source of recovery.

Connecticut takes this seriously. State law requires auto policies to provide UM/UIM bodily injury limits equal to the liability limits purchased, unless a named insured requests a lower amount in writing on a signed informed consent form, and even then the coverage cannot fall below the statutory minimum.

That creates a structural link most drivers never notice. Your UM/UIM protection is tethered to your liability limit, and carriers generally will not issue UM/UIM above the bodily injury limit on the policy. Choosing minimum liability is therefore also a decision to cap the coverage protecting your own spouse and children.

Conversion Coverage: A Connecticut Option Worth Understanding

Standard underinsured motorist coverage in Connecticut is an offset coverage. Your insurer receives credit for what the at-fault driver's liability carrier pays, so UIM fills the space between the two rather than adding to it. If the at-fault driver carries the $25,000 per-person minimum and your UIM limit is $100,000, a standard policy leaves $75,000 of additional recovery, not $100,000.

Connecticut law also provides for underinsured motorist conversion coverage, addressed at Connecticut General Statutes section 38a-336a. Under a conversion endorsement, payments by the at-fault driver's liability insurer do not reduce your underinsured motorist benefits; the coverage sits on top of what the other carrier pays. In the example above, that is the difference between $75,000 and $100,000 of additional recovery.

Conversion coverage is optional, carries additional premium, and must be made available to you as an option; wording and pricing vary by carrier. Ask at renewal whether your underinsured motorist coverage is written on a conversion basis, and if not, what changing it would involve.

Medical Payments: Small, Optional, and Underrated

Medical payments coverage, commonly called MedPay, pays medical expenses for you and your passengers regardless of fault. Because Connecticut repealed no-fault, there is no automatic first-party medical benefit built into an auto policy. Without MedPay, the injured occupants of your vehicle wait on a liability determination before anything is paid.

MedPay does disproportionate work for its cost. It absorbs health plan deductibles and coinsurance, responds for passengers whose own coverage may be thin, and pays early, while a liability claim is still months from resolution. Ask how it coordinates with your health plan.

Sizing Auto Limits to Satisfy an Umbrella

A personal umbrella sits above the auto and homeowners policies, but it only functions if the underlying policies carry the limits the umbrella carrier requires. Many umbrella carriers require auto bodily injury limits well above the state floor, commonly in the $250,000/$500,000 or $300,000/$300,000 range, though the requirement varies by carrier and by the size of the umbrella.

If the underlying auto limit falls below what the umbrella requires, because a policy was rewritten or a carrier changed, the umbrella typically responds as though the required underlying limit had been in place. The gap is uninsured, and it is one of the quieter ways a well-insured family ends up exposed.

The same discipline applies at the umbrella level to UM/UIM, which is frequently optional and separately elected. If the umbrella does not extend it, your family's protection against an underinsured driver stops at the auto policy limit no matter how large the umbrella above it. Our excess liability calculator is a starting point for sizing, and the personal umbrella overview explains how the layers fit together.

What to Do Next

Do this with the declarations page in front of you, not from memory.

• Find six lines on the declarations page: bodily injury liability, property damage liability, uninsured/underinsured motorist bodily injury, medical payments, and the two deductibles. If any read 25/50/25, that is the state floor rather than a decision.
• Compare UM/UIM to your bodily injury limit. If it is lower, someone signed a written request for reduced limits. Ask whether that is still what you want.
• Ask whether underinsured motorist coverage is written on a conversion basis, and what changing it would involve.
• Locate the umbrella's underlying limit requirement and confirm in writing that the auto policy meets it. Repeat any time a policy is rewritten or moved.
• Check whether the umbrella extends UM/UIM, and what adding it would take if it does not.
• Total the household's exposed assets honestly, including remaining career earnings. That number, not the state minimum, is what limits should be measured against.
• List every driver and vehicle, including teens with permits and students away at school, and confirm each is disclosed correctly.
