Massachusetts Requires Uninsured Motorist Coverage
Massachusetts law mandates uninsured motorist coverage on every auto insurance policy issued in the state. If you insure two or more vehicles, the requirement applies to your entire policy — you cannot decline uninsured motorist coverage to reduce your premium, and you cannot remove it from individual vehicles on a multi-car policy.
This mandate exists because 7.9% of Massachusetts motorists drive uninsured. The state requires carriers to include uninsured motorist bodily injury coverage at limits matching your liability coverage, ensuring you have protection when an at-fault driver carries no insurance. The requirement is non-negotiable and applies whether you own one car or five.

Nearly one in twelve Massachusetts drivers operates without insurance. The state's mandatory uninsured motorist coverage requirement protects you when one of these drivers causes an accident and cannot pay for your injuries.

How the Mandate Works on Multi-Vehicle Policies
Uninsured motorist coverage on a Massachusetts multi-car policy protects every listed driver and every listed vehicle. The coverage limit you select applies per accident, not per vehicle.
When you add a second or third vehicle to your policy, the uninsured motorist coverage extends automatically to the new vehicle at your existing limits. You do not pay separately for uninsured motorist coverage on each car — the premium reflects your total household exposure across all vehicles and drivers on the policy.
Massachusetts also requires underinsured motorist coverage, which pays when an at-fault driver carries liability insurance but not enough to cover your injuries. Both coverages are mandatory and cannot be waived or reduced below your liability limits.
You cannot decline uninsured motorist coverage in Massachusetts. Every carrier writing auto insurance in the state must include it at limits matching your liability coverage.
What Uninsured Motorist Coverage Pays For
The coverage pays medical bills, lost wages, and pain and suffering damages after an accident caused by an uninsured driver. It also covers hit-and-run accidents where the at-fault driver cannot be identified. If you or a household member is injured while riding in another vehicle or as a pedestrian struck by an uninsured driver, your uninsured motorist coverage applies.
Massachusetts does not require uninsured motorist property damage coverage. The mandatory coverage protects against bodily injury only. If an uninsured driver damages your vehicle, you file a claim under your own collision coverage if you carry it, or you pursue the at-fault driver directly in small claims court.

Matching Liability and Uninsured Motorist Limits
Massachusetts requires your uninsured motorist bodily injury limits to equal your liability limits. If you carry the state minimum liability coverage of $25,000 per person and $50,000 per accident, your uninsured motorist coverage must be $25,000/$50,000.
This matching requirement prevents gaps in protection. A household insuring three vehicles with higher liability limits receives the same higher uninsured motorist limits across all three cars. The premium for uninsured motorist coverage scales with your liability limits, not with the number of vehicles on your policy.
Carriers cannot offer you lower uninsured motorist limits to reduce your premium. The only way to lower the uninsured motorist portion of your premium is to reduce your liability limits, which also reduces your protection when you cause an accident.

Comparing Carriers for Multi-Vehicle Policies
Every carrier writing auto insurance in Massachusetts includes mandatory uninsured motorist coverage, but premium varies by carrier based on how they rate multi-vehicle households. Some carriers offer larger multi-car discounts; others price the second and third vehicle more favorably from the start. The uninsured motorist portion of your premium is a fixed percentage of your liability premium, so the carrier with the lowest liability rate typically delivers the lowest uninsured motorist cost as well.
When comparing quotes for a multi-vehicle policy, confirm that each quote includes uninsured and underinsured motorist coverage at limits matching your liability coverage. If a quote appears unusually low, verify the carrier has not reduced your liability limits to lower the premium — that reduction also lowers your uninsured motorist protection.
