When the Rate Increase Actually Hits
You caused an accident in Maryland. The claim closed weeks or months ago, but your premium hasn't changed yet. The surcharge doesn't appear until your policy renews — that's when the carrier re-rates your entire policy based on your current driving record, and the at-fault accident now sits in the lookback window.
Maryland carriers use a three-year lookback period measured from the accident date, not the claim-close date or the conviction date. If your accident happened in March 2024 and your policy renews in June 2024, the June renewal is when the surcharge appears. If your renewal was in January 2024, you won't see the increase until January 2025 — but it's coming, and the size of that increase varies dramatically by carrier.

3 years
Maryland carriers surcharge at-fault accidents for three years from the accident date. After three years, the accident drops off your rate calculation at the next renewal. The surcharge amount varies by carrier — some treat a single at-fault accident as a minor factor, others apply steep percentage increases.

How Maryland Carriers Calculate the Surcharge
The surcharge is not a flat dollar amount. Carriers re-rate your entire policy when the at-fault accident enters the lookback window, applying a percentage increase to your base premium. That percentage depends on the carrier's internal rating tier, your prior driving history, and whether you have accident forgiveness.
A household with two vehicles and clean records before the accident will see a smaller dollar increase than a household with three vehicles, a teen driver, and prior violations — even though the percentage surcharge is the same. The base premium is higher in the second scenario, so the percentage increase produces a larger dollar jump. This is why comparing carriers after an at-fault accident often saves more than waiting for the surcharge to age off.
The carrier that gave you the best rate before the accident is rarely the carrier that treats you best after one. Maryland's competitive market means surcharge treatment varies widely.
What Counts as At-Fault in Maryland

Rear-ending another vehicle, failing to yield, running a red light, and lane-change collisions where you merged into another car are almost always chargeable. Weather and road conditions do not remove fault — if you lost control on ice and hit another vehicle, the accident is still chargeable to you.
Not-at-fault accidents do not trigger a surcharge in Maryland. If another driver rear-ended you, ran a red light and hit you, or was cited as the at-fault party, your carrier cannot surcharge you for that claim. Comprehensive claims — theft, vandalism, hitting a deer, hail damage — are also non-chargeable. Only at-fault collisions where you were the primary cause produce a rate increase.
How Long the Surcharge Lasts and When It Drops
The three-year lookback period starts on the accident date, not the renewal date when the surcharge first appeared. If your accident happened on March 15, 2024, the surcharge remains on your policy through renewals in 2024, 2025, and 2026. At your first renewal after March 15, 2027, the accident is outside the three-year window and the surcharge drops.
The surcharge does not decrease gradually. It stays at the same percentage for the full three years, then disappears entirely at the next renewal after the three-year mark. Some carriers offer accident forgiveness programs that waive the first at-fault accident surcharge if you meet eligibility requirements — typically five years of accident-free driving before the incident. If you had accident forgiveness and used it, a second at-fault accident within the three-year window will be surcharged.
Switching carriers does not reset the lookback period. Every carrier in Maryland sees the same three-year accident history when they pull your motor vehicle report. The accident follows you until it ages past three years, regardless of how many times you switch policies. What does vary by carrier is how heavily they weight that accident in their rate calculation.
Maryland Uninsured Motorist Rate
16.9%
Nearly one in six Maryland drivers operates without insurance. An at-fault accident with an uninsured driver can leave you filing a collision claim on your own policy, triggering a surcharge even though the other driver was partially or fully responsible. Uninsured motorist coverage protects you from this scenario.

Why Shopping Carriers After an Accident Works
Carriers treat at-fault accidents differently in their rate calculations. One carrier may apply a steep surcharge to any at-fault accident, while another treats a single accident as a minor rating factor if the rest of your record is clean. A third carrier may specialize in drivers with recent accidents and price competitively for that risk profile from the start. The carrier that gave you the lowest rate before the accident is not necessarily the one that treats you best after one.
Maryland's competitive auto insurance market includes carriers writing standard, preferred, and non-standard tiers. After an at-fault accident, you may no longer qualify for a preferred-tier carrier's best rates, but a standard-tier carrier may price you lower than your current carrier's surcharged renewal. Shopping before your renewal date — when the surcharge is about to hit — gives you the chance to lock in a better rate before the increase appears on your current policy.
What To Do Before Your Next Renewal
Pull your motor vehicle report before shopping. Maryland drivers can request a copy from the MVA to confirm what carriers will see when they quote you. Verify the accident date is correct — if the date is wrong, the three-year lookback period may extend longer than it should, and you'll need to dispute the error with the MVA before shopping.
Compare quotes from at least three carriers that write in Maryland. Focus on carriers known to write drivers with recent accidents: some of the largest standard-tier and non-standard carriers in the state include Geico, Progressive, Nationwide, and Bristol West. Request quotes for the same coverage limits and deductibles you currently carry so the comparison is apples-to-apples. If you insure multiple vehicles, confirm the multi-car discount applies on each quote — adding a second or third vehicle can offset part of the accident surcharge with some carriers.
