Cheapest Full Coverage in Massachusetts

GEICO is cheapest for full coverage in Massachusetts at $83 a month. Plymouth Rock Insurance is next at $85 a month. At $24 a year separating them, either company is a reasonable starting point for a full coverage buyer. The more useful question is what each policy includes. With GEICO, a first at-fault accident will raise the rate, because GEICO does not offer accident forgiveness in Massachusetts. With Plymouth Rock Insurance, a first at-fault accident does not raise the rate at all. Drivers who have a clean record and want to keep it that way have a reason to consider Plymouth Rock Insurance despite the $2 monthly difference.

Cheapest Minimum Coverage in Massachusetts

Plymouth Rock Insurance is cheapest for minimum coverage in Massachusetts at $23 a month. Safety Insurance is second at $34 a month. That $11 monthly difference adds up to $132 a year. Safety Insurance offers an Excellent Driver Plus discount of up to 24% for drivers with a clean record going back six years. Applied to Safety's $34 base rate, that brings the rate down to roughly $26 a month. Plymouth Rock Insurance's $23 base rate still comes in lower without any discount applied. For minimum coverage buyers, Plymouth Rock Insurance holds the lead regardless of what Safety offers in discounts.

How to Choose Between Minimum and Full Coverage in Massachusetts

The right coverage level in Massachusetts comes down to vehicle value. Full coverage costs $45 more a month than GEICO's own minimum coverage rate of $38. That adds up to $540 a year. A vehicle worth less than $5,400 would cost more to insure at full coverage over ten years than it could return in a total-loss payout. What minimum coverage does not include is collision and comprehensive. Damage to a driver's own vehicle after an accident they cause comes out of pocket. Drivers with a car loan or lease need full coverage. Lenders require it as a condition of the loan.

Norfolk & Dedham Insurance and GEICO are both cheapest for drivers 70 and older in Massachusetts at $62 a month for full coverage. At the same price, the decision comes down to what kind of service a driver wants when something goes wrong. Norfolk & Dedham Insurance is a Massachusetts-only company that has operated in the state since 1825. Its agents work in the communities they cover and handle claims locally rather than through a national service center. GEICO processes claims through a centralized system and is built around a fully digital experience. For a senior driver who prefers working with a local agent for repairs and claims, Norfolk & Dedham Insurance is the stronger fit at no extra cost.

GEICO's DriveEasy program can lower the $62 rate through monitored driving for safe drivers. Norfolk & Dedham Insurance does not offer a telematics program. Drivers who want to lower the rate should ask GEICO about DriveEasy when getting a quote.

Plymouth Rock Insurance is cheapest in all 20 of Massachusetts's most populous cities. The rate ranges from $21 a month in Haverhill, Newton and Waltham to $32 a month in Brockton. In Massachusetts, the city changes what Plymouth Rock Insurance charges, not which company to call. Drivers in Brockton pay $11 more a month than drivers in Haverhill because the underlying risk in Brockton is higher, not because a different company is cheapest there. Getting a quote from Plymouth Rock Insurance is the right first step regardless of which city the driver lives in.

GEICO is cheapest after a speeding ticket or texting while driving violation at $93 a month. Arbella is cheapest after an at-fault accident at $115 a month. For drivers with a DUI, Plymouth Rock Insurance is cheapest at $135 a month. Plymouth Rock has the smallest proportional DUI surcharge of the five companies in the table. Its clean-record rate is $85 a month and its DUI rate is $50 higher. Other companies in the table charge more after a DUI despite starting from similar or lower clean-record rates.

Massachusetts controls how long those higher rates last through a state law called the Safe Driver Insurance Plan. Unlike most states where the insurer decides how long to charge a higher rate, Massachusetts caps the window at six years for both at-fault accidents and DUIs. Once six years pass from the incident date, the rate drops back toward the clean-record baseline. Massachusetts also does not require an SR-22 filing after a DUI. That is one less step Massachusetts drivers have to deal with after a conviction.
