One Driver's Accident Re-Rates Every Car
You insure three cars on one Connecticut policy. One driver had an at-fault accident. The carrier just sent your renewal notice, and the premium jumped on all three vehicles, not just the one involved in the claim. You expected an increase on that car. You did not expect the entire household policy to re-rate.
Connecticut carriers apply the at-fault accident surcharge to the policy, not to individual vehicles. When one driver on a multi-car policy causes an accident, the carrier re-rates the entire policy at renewal. Every vehicle on that policy sees the increase, because the carrier prices the household's combined risk, not each car in isolation.

$25,000 / $50,000 / $25,000
Connecticut requires $25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage. An at-fault accident that exceeds these limits triggers the surcharge and exposes the household to out-of-pocket liability.

The Surcharge Applies to the Policy
Connecticut carriers do not assign the at-fault surcharge to a single vehicle. They assign it to the policy. A multi-car policy insures multiple vehicles under one contract, with one premium calculated from the combined risk of every driver and vehicle listed. When one driver causes an at-fault accident, the carrier recalculates that combined risk at the next renewal.
The surcharge percentage varies by carrier and by the severity of the accident. A minor property-damage claim typically produces a smaller increase than a bodily-injury claim. The carrier applies that percentage to the policy's base premium, which already includes all vehicles. The result: every car on the policy sees the increase, even if only one was involved.
This is not a penalty. It is how multi-car policies work. The carrier prices the household as a unit. One driver's accident changes the household's risk profile, so the entire policy re-rates. Separating the at-fault driver onto a different policy does not remove the surcharge from the original policy until the next renewal cycle, because the accident remains on the driver's record and follows them to the new policy.
Carriers writing in Connecticut that handle multi-car policies include Allstate, Geico, Progressive, State Farm, Travelers, and Farmers. Each applies its own surcharge schedule. The increase duration typically runs three to five years from the accident date, not the renewal date.
The at-fault surcharge applies to your entire Connecticut multi-car policy at renewal. One driver's accident re-rates every vehicle on the household contract.
How the Increase Appears at Renewal
Connecticut law requires carriers to notify you of a premium increase before renewal. The notice does not always itemize the surcharge separately. It shows the new total premium for the policy. If you call the carrier, they will confirm that the increase resulted from the at-fault accident and tell you the surcharge percentage they applied. Some carriers show the surcharge as a line item on the declarations page; others fold it into the base premium calculation.
The surcharge takes effect at the renewal following the accident. If the accident happened mid-term, your current premium does not change. The increase appears when the policy renews. Once applied, the surcharge remains on the policy for the carrier's standard lookback period, typically three years. After that period, the accident ages off your record and the surcharge drops at the next renewal, assuming no new at-fault claims.

Why Splitting the Policy Does Not Help
Some households consider moving the at-fault driver to a separate policy to isolate the surcharge. This does not work the way most people expect. The accident remains on the driver's motor vehicle record for three to five years. Any carrier quoting that driver will see the accident and apply their surcharge to the new policy. Moving the driver off your household policy removes one vehicle from your multi-car discount, which often increases the per-vehicle rate on the remaining cars.
The math rarely favors splitting. The at-fault driver's new policy will carry the surcharge. Your remaining household policy loses the multi-car discount benefit of the removed vehicle. You pay two policy fees instead of one. The combined premium across both policies typically exceeds what you would pay keeping everyone on one policy, even with the surcharge applied.
Carriers price multi-car policies with a discount because insuring multiple vehicles under one contract reduces administrative cost and increases customer retention. Removing a vehicle from that policy removes part of the discount calculation. The remaining vehicles may see a per-vehicle rate increase even without the surcharge, because the policy no longer qualifies for the same multi-car tier.

11.8%
11.8% of Connecticut motorists drive uninsured. An at-fault accident with an uninsured driver still triggers the surcharge on your policy, even if you carry uninsured motorist coverage and file a claim under your own policy.

What Happens After Three Years
Most Connecticut carriers apply the at-fault surcharge for three years from the accident date. Some extend it to five years for severe claims involving bodily injury or multiple vehicles. After the surcharge period ends, the accident ages off your driving record for insurance purposes. The carrier removes the surcharge at your next renewal, and your premium drops back to the base rate for your household's current risk profile.
The surcharge does not disappear automatically. It drops at the renewal following the end of the lookback period. If your accident happened in January 2023 and your carrier applies a three-year surcharge, the increase remains on your policy through renewals in 2024, 2025, and 2026. At your 2027 renewal, the surcharge drops, assuming no new at-fault claims during that period.
Compare Carriers at Your Next Renewal
Connecticut carriers apply different surcharge schedules. One carrier may apply a 30% increase for three years; another may apply 20% for five years. The total cost over the surcharge period varies by carrier. When your renewal notice arrives, compare quotes from at least three carriers that write multi-car policies in Connecticut. Allstate, Geico, Progressive, State Farm, Travelers, and Farmers all write households with at-fault accidents on record.
Request quotes for your entire household. Give each carrier the same vehicle, driver, and coverage information. Compare the total annual premium across all vehicles, not just the per-vehicle rate. Some carriers offer accident-forgiveness programs that waive the first at-fault surcharge after a set number of claim-free years. Ask each carrier whether you qualify. If you do, the accident may not trigger a surcharge at all, and your premium remains at the base rate.
