An ignition interlock is a device which measures any amount of alcohol contained in a driver's body. Before starting the car the driver must blow into a tube emanating from the ignition interlock device. If the device then detects a blood alcohol concentration (BAC) higher than is permitted by law the car will not start and the violation will be reported to the prosecutor, the probation officer, and/or the judge.

Liability Laws

Massachusetts Dram Shop Law

Massachusetts has a modified Dram Shop Law. Dram Shop Law refers to the liability of private social hosts, bars, hotels nightclubs and other commercial establishments who sell or deliver alcohol to patrons or to minors for injuries intoxicated patrons or minors cause to third parties such as in car accidents.

A private social host is the host at a private party, such as a wedding reception, a corporate sponsored event, a gathering of friends at a private residence, where alcohol is served not for profit.

Under Massachusetts law, it is a violation of the liquor laws for a social host or a commercial establishment to sell or deliver alcohol to a minor or an intoxicated person.

However, the law stops there. Even if a social host or a commercial establishment is found to have violated the liquor control law, they are not liable for the actions of the intoxicated person. For violating the liquor control laws, such as knowingly providing alcohol to a minor or selling alcohol to a visibly intoxicated person, a social host or a commercial establishment can be fined, and the establishment may lose its liquor license.

For an injured third party to succeed in a claim for personal injuries or property damage against a commercial establishment or social host, the injured third party must file a lawsuit alleging negligence by the establishment or the social host. While presenting a case in court, the injured third-party may cite the violation of liquor control laws by the establishment or the social host.
Section 1-20-138-64A
Section 1-20-138-69

Massachusetts Insurance Information

Comparative Negligence (51% Rule)

In Massachusetts, the victim in a car accident can sue the negligent driver for compensation. The victim's liability in causing the accident, their comparative negligence, affects the amount of compensation the victim receives.

If the victim contributed less than 51% of the negligence that caused the accident, then their compensation is reduced by the amount they contributed to the accident. If the victim contributed 51% or more of the negligence that caused the accident, then the victim is barred from receiving any compensation.
Section 3-2-231-85

Example of Comparative Negligence (51% Rule)

One morning, Jackson was driving north on his way to work. At an intersection, he pulled into the left turn lane. At the same time, Melanie approached the intersection from the opposite direction. Suddenly, Jackson turned left into Melanie's lane and their cars collided.

Melanie sustained serious brain injuries and damage to her car, totalling in $100,000 dollars worth of damages.

After their investigation, the police determined that Jackson had failed to yield according to traffic laws. A pedestrian witness told police he saw Melanie texting at the time Jackson's car crashed into Melanie's. As a result, the police issued Melanie a citation for using a mobile device while driving.

Melanie sued Jackson for $100,000 and claimed he was 100% at fault for the accident because he did not yield to her right-of-way. At trial, the jury found Jackson liable for failing to yield the right-of-way. However, the jury also found Melissa liable for using a mobile device while driving and partially responsible for the accident.

The verdict stated Jackson's negligence equaled 70% of the accident, and Melanie's equaled 30%. The jury awarded Melanie only $70,000 dollars.

In the event the jury had found Jackson's negligence equaled 49% of the accident, and Melanie's equaled 51%, the jury would be barred by law from awarding Melanie any compensation for the damages.
Comparative Negligence: Section 3-2-231-85
Right of Way: Section 1-14-89-8
Drivers and Mobile Electronic Devices: Section 1-14-90-13B

Massachusetts's No Fault Car Insurance

In Massachusetts, no-fault insurance allows a person, who is injured in a car accident or whose property is damaged, to file a claim with their own car insurance company.

No-fault insurance allows a person to avoid pursuing a negligent driver for compensation for damages. No-fault insurance does not compensate for pain and suffering, and the amount of personal injury protection (PIP) insurance purchased by the injured party determines their coverage.
Section 1-14-90-34M

Statute of Limitations

Massachusetts has a three (3) year statute of limitations for personal injury claims. This means if a driver, passenger, or passerby is injured at the hands of a negligent driver, the victim must either file their claim within three (3) years following the car accident, or the victim is barred from pursuing the negligent driver in court.
Section 3-5-260-2A

Small Claims Courts

In Massachusetts, victims of car accidents can choose to sue the negligent driver in small claims court. The jurisdiction of a small claims court regarding personal injury and property damage is limited to a maximum of $5,000, exclusive of filing fees and court costs.

For information about filing a claim in small claims court, see the State of Massachusetts Consumer Resources website.

Massachusetts Government Tort Claims - Sovereign Immunity

In Massachusetts, it is possible to submit a claim against a governmental agency or its employees for personal injury or property damage as a result of negligence on the part of the governmental agency or its employees. The claim must refer to an lawful action on the part of the governmental agency or employee performed in the scope of their duties.

If the injury or property damage occurred as a result of an unlawful action, then the claimant can sue only the person(s) who caused injury or property damage individually. The governmental agency would not be liable.
Section 3-4-258-2


If Melissa, an engineer with the Boston Planning Department, ran a red light on her way to a worksite and caused an accident, then the City of Boston would be liable for the property damage and personal injuries caused by her.

If Melissa stopped for a few drinks and became intoxicated before heading to a worksite and causing an accident, then the City of Boston can claim sovereign immunity. Melissa performed an unlawful act and was not acting in the scope of her duties when she became intoxicated on her way to the worksite.

To seek compensation for damages, injured parties would have to sue Melissa personally. The determination of whether or not Melissa was acting within the scope of her duties would have to be decided during a trial.

Massachusetts places a cap of $100,000 on the maximum amount of damages that can be claimed against a government agency or its employees.
