- Minimum liability coverage limits increased — Massachusetts raised required limits for bodily injury and property damage to higher amounts to match modern accident costs.

- New limits kicked in July 1, 2025 and apply to policies issued or renewed on or after that date.
- Drivers with state-minimum plans may see higher premiums because more coverage usually means higher cost, especially if previously insured at older lower limits.

If you’re a Massachusetts driver, prepare for some major changes to your mandated car insurance limits this summer.
Massachusetts enacted substantial reforms to its auto insurance laws on July 1, 2025 — the first significant update in over three decades. These changes aim to enhance financial protection for drivers but may also lead to increased insurance premiums.
This article breaks down the key modifications and their potential impact on Massachusetts drivers.
What’s changing for Massachusetts drivers?
Massachusetts’ new auto insurance law raises the minimum coverage requirements for liability from 20/40/5 to 25/50/30. The new coverage limits are as follows:
- Bodily injury liability: $25,000 per person (previously $20,000), $50,000 per accident (previously $40,000)
- Bodily injury caused by uninsured auto: $25,000 per person (previously $20,000), $50,000 per accident (previously $40,000)
- Property damage liability: $30,000 (previously $5,000) per accident
These increased limits are meant to keep up with medical and repair costs, which have significantly increased since the law was last changed in 1988.
The new limits offer better protection than previous limits, but drivers with state minimum coverage can expect their premiums to increase to account for this increased protection.
“While every policyholder’s experience will be different, policyholders who have limits at the current minimum amount should be aware they will generally see an increase to their premium as they are now required to purchase increased coverage limits,” said Michele J. Campbell, director of communications for the Massachusetts Office of Consumer Affairs and Business Regulation.

What is not changing in Massachusetts?
Some mandatory coverages will remain the same after the Massachusetts House Bill H.5111 takes effect in July. The following coverage limits will not be changing:
- Uninsured motorist bodily injury coverage (UM): $20,000 per person/$40,000 per accident. This coverage protects you and your passengers if you’re injured in an accident caused by an uninsured driver.
- Personal injury protection (PIP): Remains at $8,000 per person, per accident. PIP covers medical bills and 75% of lost wages, up to the coverage amount, no matter who is at fault in the accident. It covers you as the driver and anyone injured in the accident, including passengers or pedestrians. PIP covers medical expenses, up to 75% of lost wages and replacement services up to $8,000.
Impact on insurance premiums
Because the law increases mandatory coverage, drivers with Massachusetts state minimum coverage can expect an annual premium increase. In 2025, before the changes to the law, the average price of state minimum car insurance in Massachusetts was $511.
The changes are the first since 1988, when the average price of a new car was $13,262 (compared to $49,740 in 2025). Even with the changes, the new requirements may still be insufficient to keep up with inflation.
The new minimums will be applied on a rolling basis as policies renew, so you may not see a change to your premiums until you renew or request a quote after July 1. Those who have limits at the current state minimum limits will see automatic increases to those limits to the new state minimums when they renew their policy.
“The Massachusetts auto insurance market is very competitive, and consumers should be reminded that shopping around is their best option for finding the coverage they need at a price that works for them,” Campbell said. “Maintaining a clean driving record is also an important factor in keeping policy premiums lower.”

Steps for Massachusetts drivers
Choosing only the state minimum car insurance may leave Massachusetts drivers underinsured.
As a Massachusetts policyholder, you should review your coverage to ensure it suits your needs. You should also talk with your insurance agent to understand how these changes may affect your premiums, as insurers use multiple rating factors to set car insurance rates.
Insurers aren’t required to notify customers of the coming policy changes, so don’t let it take you by surprise. You might want to shop around to compare quotes if you’re looking for savings.
“The Division of Insurance’s Consumer Service Unit stands ready to be a resource for Massachusetts consumers with questions about the new limits,” Campbell said.
