Massachusetts Car Insurance Requirements: Minimums, Fault Rules & Penalties

Minimum liability requirements

Massachusetts mandates several coverage types for all registered vehicles. The required minimums include:

Coverage	Minimum limit
Bodily injury per person	$20,000
Bodily injury per accident	$40,000
Property damage per accident	$5,000
Personal Injury Protection (PIP)	$8,000 per person
Uninsured motorist — per person	$20,000
Uninsured motorist — per accident	$40,000

Two aspects of these minimums stand out. First, the $5,000 property damage limit is notably low — well below the cost of repairing most modern vehicles involved in a serious collision. Carrying higher property damage limits is advisable. Second, PIP at $8,000 is a first-party coverage, meaning it pays your own costs rather than the other driver's, regardless of who caused the accident.

No-fault PIP system

Massachusetts is a no-fault state. After any accident, you turn first to your own PIP coverage for medical expenses and lost wages — not to the at-fault driver's liability policy.

PIP pays:

• Up to $8,000 in medical expenses per person
• 75% of lost wages up to the $8,000 per-person limit
• Replacement service costs (e.g., household services you cannot perform due to injury)

Coverage applies to the policyholder, household family members, and passengers in the vehicle. PIP pays regardless of who caused the crash.

Stepping outside the no-fault system: Massachusetts allows tort claims against the at-fault driver only when injuries meet one of these thresholds:

• Medical expenses exceed $2,000
• The injured person suffers death, loss of a body part, permanent and serious disfigurement, loss of sight or hearing, or a fracture

When the threshold is met, the injured party can pursue pain and suffering damages through a liability claim or lawsuit against the at-fault driver. When it is not met, PIP is the primary remedy.

Insurance pricing rules

Massachusetts, like California, prohibits insurers from using credit scores to set auto insurance rates. This is a significant consumer protection. Rates in Massachusetts must be based on driving record, claims history, vehicle type, and territory — not creditworthiness, education, or occupation.

Rate changes are subject to approval by the Massachusetts Division of Insurance. The state also has a merit rating system that rewards clean driving records with lower premiums over time.

SR-22 and the Massachusetts Auto Insurance Plan (MAIP)

Massachusetts does not use SR-22 certificates. Drivers who are required to demonstrate financial responsibility — typically after a serious violation, license revocation, or period of uninsurance — are often directed into the Massachusetts Auto Insurance Plan (MAIP).

MAIP is a state-administered assigned risk pool that ensures high-risk drivers can obtain coverage even when standard market insurers decline them. Carriers that write auto insurance in Massachusetts are required to participate in MAIP and accept assigned risks in proportion to their market share.

MAIP coverage is typically more expensive than standard market coverage. Drivers assigned to MAIP can return to the voluntary market once they have maintained a clean record for a sufficient period.

Penalties for driving without insurance

Massachusetts applies substantial penalties for uninsured driving, with fines that significantly exceed most other states.

Offense	Fine	License suspension
First offense	$500–$5,000	60 days
Subsequent offenses	Higher fines	Up to 1 year

Beyond the fines and suspension, a conviction for driving without insurance creates a record that follows a driver into the insurance market. Combined with any underlying violation that led to the lapse, this can result in significantly higher premiums and potential MAIP placement for multiple years.

Massachusetts takes an active approach to insurance compliance enforcement. Vehicles are checked at registration renewal, and insurers are required to notify the Registry of Motor Vehicles (RMV) when a policy is cancelled or non-renewed. Drivers switching insurers should ensure the new policy is active before the old one ends to avoid any gap that could trigger RMV action.
