Raising liability limits from 50/100/50 to 100/300/100 adds only about $42 a year on average in our Brunswick data, with the same $500 deductibles. The full-coverage package doubles the per-person injury limit, triples the per-crash limit and doubles the property damage limit, and it raises uninsured and underinsured motorist coverage to 100/300.

What Car Insurance Is Required in Brunswick?
In Brunswick, as everywhere in Maine, an auto policy must include at least:
- 50/100/25 liability coverage: $50,000 per person and $100,000 per crash for injuries and $25,000 for property damage
- $2,000 per person in medical payments coverage for you and your passengers, plus uninsured and underinsured motorist coverage of at least $50,000 per person and $100,000 per crash
- Up to $500 in towing and storage coverage when police have your car towed after a crash, on policies issued or renewed after July 1, 2024
Our Brunswick liability-only price, $469 a year against $1,620 for full coverage, uses 50/100/25 limits with 50/100 uninsured and underinsured motorist coverage, so it doesn’t include the medical payments and towing coverage Maine also requires. Our Maine requirements guide covers the details and the penalties for driving uninsured.
How to Lower Your Car Insurance Rate in Brunswick
- Compare Travelers and GEICO first. They have the two lowest full-coverage averages among insurers anyone can buy from in our Brunswick table, about $91 and $96 a month.
- Quote several insurers. In our Brunswick table, the lowest and highest averages among insurers anyone can buy from are about $80 a month apart for the same driver and car.
- New to Maine? You have 30 days after becoming a resident to get a Maine driver’s license, according to the Bureau of Motor Vehicles, and 30 days to register your vehicles, which requires proof of insurance, according to the bureau.
- Compare at every renewal. Over the past nine months, State Farm has cut its Brunswick average 9.3%, while Concord Group has raised its average 16.2% and Allstate 2.8%, so the order in our table can shift.
- Ask about discounts and check your deductible. Many insurers lower rates for a clean driving record, paying in full or insuring more than one car, so ask which discounts you qualify for. Our full-coverage prices use $500 deductibles. A higher deductible lowers your premium but means you pay more yourself after a claim; see how car insurance deductibles work.
- Bundle your car and home insurance. Many insurers discount both policies when you buy them together. Check Maine home insurance rates, and compare homeowners insurance quotes before you shop. Renters can often bundle a renters insurance policy too.

How We Calculated Brunswick Car Insurance Rates
Insurers must file their rates and rating rules with each state’s insurance regulator. Quadrant Information Services uses those filings to calculate what each insurer would charge a specific driver, and InsuranceQuotes analyzes those prices. This page uses rates in effect on Aug. 31, 2026.
- Sample: five full-coverage premiums from five insurers in Brunswick’s ZIP code, 04011, plus the same number of liability-only and 50/100/50 premiums.
- Driver: a single 40-year-old driver, licensed 24 years, with good credit and no accidents or violations, driving a 2024 Toyota Camry LE they own, for personal use.
- Coverage: full coverage is 100/300/100 liability with $500 comprehensive and collision deductibles and 100/300 uninsured and underinsured motorist coverage. We also price 50/100/50 with the same deductibles, and liability-only coverage at 50/100/25 limits, with 50/100 uninsured and underinsured motorist coverage and no comprehensive or collision. Maine’s minimum policy also requires $2,000 in medical payments coverage and, for policies issued or renewed after July 1, 2024, $500 in towing and storage coverage. Our liability-only prices don’t include those two coverages, so they aren’t the price of a policy that meets every Maine requirement.
- Calculation: for each insurer we take its lowest eligible price in Brunswick’s ZIP code, 04011. The overall average is the mean of those prices. Monthly figures are annual premiums divided by 12 and rounded.
- Rankings: we name a cheapest insurer only where it’s priced in that ZIP code and its lead over the next insurer isn’t so wide that it looks like an outlier. Annual prices within 3% of each other are called effectively tied. An insurer marked * is named cheapest only when it’s priced below every major insurer we compared and at least half of the statewide rate studies we cite rank it cheapest.
- Rate changes: we compare the same insurer in the same ZIP code, for the same driver and coverage, in rates as of Nov. 30, 2025, and Aug. 31, 2026. All five insurers are in both sets of rates. Rate-change percentages are calculated from the annual premiums shown; other percentages use the rounded monthly figures.
- Insurers marked *: priced from published Maine rate studies, scaled to our benchmark driver. They aren’t included in our averages.
- What this isn’t: a quote. These are modeled prices for one driver profile, calculated from insurers’ rate filings. Your price depends on your ZIP code, vehicle, driving record, coverage choices and discounts.
Coverage requirements come from Maine law and the Maine Bureau of Insurance. We refresh these figures when new rate data is released.
