What Happens If You Crash Without Insurance in Massachusetts?

If you cause a crash in Massachusetts while driving an uninsured vehicle, you face a criminal charge under M.G.L. c. 90, sec. 34J, a license suspension of 60 days on a conviction or guilty plea, and personal responsibility for every dollar of the other person’s losses, starting with the first one. No insurer defends you or pays on your behalf. Your own medical bills have no personal injury protection behind them, and the state’s backup plan for people without that coverage is closed to the owner of an uninsured vehicle and to that owner’s household.

A few terms are used throughout. An uninsured vehicle here means a vehicle that must be registered in Massachusetts and has no motor vehicle liability policy in force on the day of the crash. Personal injury protection, or PIP, is the part of a Massachusetts auto policy that pays medical bills and lost wages up to at least $8,000 for each person, whoever caused the crash. The tort exemption is the rule that shields an insured driver from being sued for the losses PIP covers. Subrogation is an insurer’s right to step into the place of the person it paid and collect that money from whoever was legally responsible. The assigned claims plan is the insurer-run program that pays PIP benefits to some people who have no policy to claim under. A judgment debtor is a person a court has ordered to pay money to someone else.

The Short Version, in Order

The consequences arrive from four directions, and they do not wait for each other.

1. The police and the court. Operating an uninsured vehicle is a crime. The charge can be brought whether or not you caused the crash.
2. The Registry of Motor Vehicles. A conviction or guilty plea brings a license suspension, and the registration of an uninsured vehicle can be revoked.
3. The injured person, and that person’s insurer. You are personally liable for the harm you caused, and the insurer that pays the injured person can come after you for what it paid.
4. Your own losses. Your medical bills, your lost wages and your car have no policy behind them.

Each of these comes from a specific section of the General Laws. The rest of this page takes them one at a time.

The Criminal Charge: M.G.L. c. 90, sec. 34J

Section 34J applies to anyone who “operates or permits to be operated or permits to remain on a public or private way” a motor vehicle that is required to be insured and is not. That wording reaches three people: the driver, the owner who lent the car, and the owner who left an uninsured car parked on the street.

The penalty in the statute is a fine of “not less than five hundred nor more than five thousand dollars or by imprisonment for not more than one year in a house of correction, or both”. The last sentence of the section treats a first offense differently: a person who has not previously been found responsible for or convicted of a violation “shall be punished by fine of not more than $500”.

Three more consequences follow a conviction or a guilty plea, and the statute lists them separately from the fine:

• A payment to the insurance plan. The person is liable to the plan organized under c. 175, sec. 113H for “the greater of five hundred dollars or one year’s premium for compulsory motor vehicle insurance for the highest rated territory and class or risk in effect at the time”. The statute says this is in addition to every other liability, civil or criminal.
• A 60-day suspension. The license or right to operate is suspended for sixty days once the Registrar is notified by the court clerk.
• A one-year suspension for a repeat. A second or later conviction or guilty plea within six years brings a suspension of one year.

The statute also sets out how the charge is proved. A written certification from the Registrar that the Registry has no record of a policy for the vehicle on that date is admissible and creates a rebuttable presumption that the vehicle was uninsured. The same sentence says the presumption “may be rebutted and overcome by evidence that a motor vehicle liability policy or bond or deposit was in effect”. A driver whose policy was in force and simply not on the Registry’s record should keep the declarations page, the payment record and any letter from the insurer.

The Registration

A Massachusetts registration depends on insurance from the first day. Under M.G.L. c. 90, sec. 1A, a vehicle cannot be registered unless the application comes with an insurance certificate, and the Registrar “may revoke without a hearing any certificate of registration” once satisfied that the insurance has not been maintained for the life of the registration.

When an insurer cancels a policy, c. 90, sec. 34H directs the Registrar to revoke the registration on the effective date of the cancellation unless a new certificate covering the same vehicle has been received in time. So a lapse usually means two problems on the day of a crash: an uninsured vehicle, and a registration that has been or will be revoked.

What You Owe the Other Person

Massachusetts decides who pays by fault, and insurance is not part of that question. An uninsured driver who caused the crash is liable for the injured person’s medical bills, lost wages, pain and suffering, and property damage. The difference is who pays: an insured driver’s policy would respond up to its limits, which for policies issued or renewed on or after July 1, 2025 are at least $25,000 for one person and $50,000 for one crash under c. 90, sec. 34A, and at least $30,000 for property damage under sec. 34O. An uninsured driver pays from wages, savings and property.

The first $8,000 is yours too

This is the part most people miss. In an ordinary crash the injured person’s first medical bills and lost wages are paid by PIP, and the driver who caused the crash cannot be sued for them. That protection comes from c. 90, sec. 34M, and it is limited by its own words to an owner or operator “of a motor vehicle to which personal injury protection benefits apply”. An uninsured vehicle is not one. The exemption does not attach, and the claim against the uninsured driver starts at the first dollar.

The insurer that paid can sue you

The injured person will usually have PIP on their own policy, and that insurer will pay it. Section 34M then gives the insurer a claim of its own: an insurer paying PIP benefits “shall be subrogated to that exact extent to the rights of any party it pays and may bring an action in tort against any person liable for such damages in tort who is not exempt”. Between two insured drivers this is settled insurer to insurer. Against an uninsured driver it arrives as a demand letter addressed to the driver, and then as a lawsuit.

The same thing happens with the injured person’s uninsured motorist coverage. Every Massachusetts policy must carry it under c. 175, sec. 113L, for the protection of insured people “who are legally entitled to recover damages from owners or operators of uninsured motor vehicles”. After the insurer pays, paragraph (4) of that section entitles it to the proceeds of any settlement or judgment against the person legally responsible, once its own insured has been fully compensated. The injured person being paid does not end the matter. It changes who is asking.

Pain and suffering

The injured person can recover pain and suffering from the driver at fault if the claim clears the threshold in c. 231, sec. 6D: reasonable and necessary medical expenses over $2,000, or a death, the loss of a body member, permanent and serious disfigurement, a described loss of sight or hearing, or a fracture. That threshold is the same whether the driver at fault is insured or not.

An unpaid judgment can cost the license

If the injured party sues and wins, the judgment is a debt. For property damage, c. 90, sec. 22A adds a Registry consequence: after a hearing, the Registrar “shall suspend any license to operate motor vehicles issued to a judgment debtor” in an action for property damage arising from the use of a motor vehicle, where the court has found that the debtor “willfully and intentionally failed to pay” under a payment order. The section does not apply to a debtor who was insured for at least $5,000 for that liability, which is why it falls on uninsured drivers. The license comes back when the judgment is satisfied, when the amount is deposited with the clerk, or when the debtor shows the failure to pay was not wilful.

Your Own Injuries

An insured driver who is hurt has PIP no matter who caused the crash. An uninsured driver has to look elsewhere, and two doors are closed by statute.

No PIP on the vehicle. PIP is a provision of the policy on the car. No policy, no PIP.

No assigned claims plan. Massachusetts has a backup for residents with no PIP available to them. Section 34N opens it to “any person resident in the commonwealth, other than the owner or registrant of a motor vehicle not insured by a policy or bond providing personal injury protection or a member of such owner or registrant’s household”. The owner is excluded, and so are the people who live with the owner. A spouse or child riding in the uninsured car is shut out of the plan along with the person who let the policy lapse.

What remains:

• Health insurance. A health plan is the usual source of payment for the uninsured driver’s own treatment.
• A household member’s auto policy. Section 34A extends PIP to a named insured and “members of their households” who are hurt in a vehicle that has no PIP. A person who lives with an insured relative should read that policy and ask that insurer before assuming there is nothing. Whether a particular policy pays depends on its terms.
• A claim against the other driver. If the other driver was at fault, wholly or partly, the uninsured driver can still bring a claim. That situation has its own page: what happens when you had no insurance and were not at fault.

Your Car

Collision coverage is optional coverage on a driver’s own policy under c. 90, sec. 34O. With no policy there is no collision coverage, so an uninsured driver who caused the crash repairs or replaces the car alone. If the other driver was at fault, that driver’s property damage liability coverage is the source, reduced by any share of fault the uninsured driver carries.

Answer Capsule

Crashing without insurance in Massachusetts brings four separate consequences. First, operating an uninsured vehicle is a crime under M.G.L. c. 90, sec. 34J: a fine of $500 to $5,000, up to one year in a house of correction, or both, with the fine capped at $500 for a first offense. A conviction or guilty plea also brings a 60-day license suspension (one year for a second within six years) and a payment to the state insurance plan of the greater of $500 or one year’s compulsory premium. Second, the Registrar may revoke the registration of an uninsured vehicle under c. 90, secs. 1A and 34H. Third, a driver who caused the crash is personally liable from the first dollar, because the tort exemption in c. 90, sec. 34M protects only vehicles to which PIP applies, and the injured person’s insurer may sue to recover what it paid. Fourth, the uninsured driver has no PIP, and c. 90, sec. 34N bars the owner of an uninsured vehicle and the owner’s household from the assigned claims plan. Lack of insurance does not decide fault.

Does Having No Insurance Make the Crash Your Fault?

No. Fault turns on how each person drove. Under the comparative negligence statute, c. 231, sec. 85, a person can recover damages if their own negligence “was not greater than the total amount of negligence attributable to the person or persons against whom recovery is sought”, and the damages are reduced in proportion. The same section says a plaintiff’s violation of a criminal statute is evidence of negligence where it “contributed to said injury”, and that the violation does not by itself bar recovery. Driving without a policy is a crime, and it does not cause a collision.

That cuts both ways. An uninsured driver who was rear-ended at a red light is not liable for the crash because of the missing policy. An uninsured driver who ran the light is liable because of the light.

Three Situations Compared

	Uninsured and at fault	Uninsured and not at fault	Insured and at fault
Criminal charge under c. 90, sec. 34J	Yes	Yes	No
License suspension on conviction or plea	60 days; one year for a second within six years	Same	None under sec. 34J
The other person’s first $8,000 of medical bills and wages	Owed personally; no tort exemption	Not owed	Paid by PIP; driver is exempt under sec. 34M
The other person’s pain and suffering	Owed personally if the sec. 6D threshold is met	Not owed	Paid by the policy up to its limits
Your own medical bills	Health insurance or a household member’s policy; no assigned claims plan for an owner	Same, plus a claim against the driver at fault	Your own PIP
Your own car	Your cost	The other driver’s property damage coverage	Your collision coverage, if you bought it

Was the Vehicle Really Uninsured?

Three situations are often confused with driving uninsured.

You have no policy, but the car you drove did. Massachusetts compulsory insurance covers the vehicle. The policy defined in c. 90, sec. 34A protects the owner and a person operating the vehicle with the owner’s express or implied consent. A driver with no policy of their own who borrows an insured car with permission is generally driving an insured vehicle.

You borrowed a car that turned out to be uninsured. Section 34J punishes whoever “operates” the vehicle, so the driver can be charged along with the owner who permitted it. On the injury side the driver is in a better position than the owner: the sec. 34N exclusion from the assigned claims plan names the owner or registrant and that person’s household, and nobody else.

Your policy was cancelled and you did not know. The Registry’s record creates only a presumption under sec. 34J, and it can be rebutted. Whether a cancellation took effect on the date the insurer says is a question worth checking before anything else, because it decides whether there is an insurer to call.

What to Do After the Crash

1. Stay at the scene and exchange information. Leaving turns one problem into a second and more serious one. See the penalties for leaving the scene in Massachusetts.
2. File the crash report. Under c. 90, sec. 26, every operator in a crash involving death, injury or more than $1,000 of damage to any one vehicle or other property must report in writing to the Registrar within five days and send a copy to the local police. The Registrar may suspend or revoke a license for not reporting. See how to report a car accident in Massachusetts.
3. Do not drive the vehicle again until it is insured. Each trip is a new violation of sec. 34J.
4. Get treatment and tell the provider how you will pay. Use health insurance, and check whether anyone in your household has an auto policy.
5. Gather the insurance paper trail. The last declarations page, payment records, and any cancellation notice, with its envelope if you have it.
6. Open every letter. A subrogation demand from an insurer, a notice from the Registry and a court summons each carry a deadline. An ignored lawsuit ends in a default judgment for the full amount claimed.
7. Get advice on both tracks. The criminal charge and the civil claim are separate proceedings, and what is said in one can be used in the other.

How Long the Exposure Lasts

A person injured in the crash has three years to bring a tort action under c. 260, sec. 2A. An uninsured driver who hears nothing for a year has not been released from anything. Insurers that have paid a claim often send a subrogation demand long after the crash, once their own file is closed.

For the rules an insured driver works under, see Massachusetts car insurance requirements, how PIP works, uninsured and underinsured motorist coverage and whether Massachusetts is a no-fault state.

Frequently Asked Questions

Q: Is driving without insurance a crime in Massachusetts?

A: Yes. M.G.L. c. 90, sec. 34J punishes operating an uninsured motor vehicle, or permitting one to be operated or to remain on a public or private way, with a fine of $500 to $5,000, imprisonment for up to one year in a house of correction, or both. For a person with no earlier finding or conviction under the section, the fine is not more than $500.

Q: Will I lose my license for crashing without insurance?

A: A conviction or guilty plea under c. 90, sec. 34J brings a 60-day suspension of the license or right to operate, and a one-year suspension for a second or later offense within six years. Separately, under c. 90, sec. 22A, a driver who wilfully fails to pay a court-ordered property damage judgment from a crash can be suspended after a hearing until the judgment is dealt with.

Q: Can I be sued personally if I had no insurance?

A: Yes. The injured person can sue the driver at fault, and so can an insurer that paid the injured person. Under c. 90, sec. 34M, an insurer that pays PIP benefits may bring a tort action against a liable person who is not exempt, and the exemption covers only vehicles to which PIP applies.

Q: Who pays my medical bills if I was uninsured and caused the crash?

A: Not PIP, because PIP is part of the policy the vehicle did not have. The assigned claims plan is closed to the owner or registrant of an uninsured vehicle and to members of that person’s household under c. 90, sec. 34N. Health insurance is the usual source, and a household member’s auto policy is worth checking.

Q: Does being uninsured mean I am automatically at fault?

A: No. Fault depends on how the crash happened. Under c. 231, sec. 85, a statutory violation is evidence of negligence only where it contributed to the injury, and having no policy does not cause a collision.

Q: What if I was driving someone else’s insured car and have no policy of my own?

A: The compulsory policy defined in c. 90, sec. 34A covers the vehicle and a person operating it with the owner’s express or implied consent. A driver with permission is generally covered by the owner’s policy, so this is usually not an uninsured crash.

Q: What if the other driver was partly at fault?

A: Massachusetts compares fault. If your share is not greater than the total share of the people you are claiming against, you can recover damages reduced by your percentage under c. 231, sec. 85, and the other driver can do the same against you. Being uninsured does not remove your claim, and it does not shield you from theirs.

Q: How long can someone wait before suing me?

A: An action for personal injuries must be commenced within three years after the cause of action accrues under c. 260, sec. 2A.

Talking to a Lawyer

A crash without insurance runs on two tracks at once: a criminal charge with a Registry consequence, and a civil claim that can come from the injured person or from an insurer. If you were hurt in the crash yourself, or the other driver shares the fault, your own claim is still alive and the deadlines are already running. Call Jim Glaser Law at (617) JIM-WINS.
