Who Is Liable for an Amusement Ride or Trampoline Park Injury in Massachusetts?

Massachusetts licenses and inspects powered amusement rides under M.G.L. c. 140, sec. 205A, and that statute builds a paper trail almost nobody asks for. After an injury requiring medical treatment the ride must close immediately, the owner has 48 hours to notify the state in writing, state inspectors must investigate, and the owner and the operator must each keep a log of maintenance, repairs, inspections and every accident. A trampoline park is a different question, because sec. 205A defines an amusement device as a powered mechanical ride, so a trampoline court or a bounce house usually runs on ordinary premises liability and on the release signed at the door. If you or your child were hurt at a park, a carnival or a trampoline facility, the Jim Glaser Law line at (617) JIM-WINS is answered 24 hours a day, and the first telephone consultation is offered without charge.

The Statute Almost Nobody Reads Until They Need It

Most people hold one of two beliefs about the ride that hurt them. Either somebody official checked it, or nobody did and it arrived on a flatbed truck last Tuesday. Massachusetts sits between those two ideas, and where exactly it sits turns out to matter a great deal to an injured rider.

M.G.L. c. 140, sec. 205A makes running a powered ride a licensed activity:

No person shall, individually or through an agent, operate or cause to be operated a ferris wheel, carousel, inclined railway or similar amusement device unless such person has obtained a license from the commissioner.

The commissioner here is the head of the division of occupational licensure. The license is not a rubber stamp. The statute conditions it on proof of liability insurance and on a certification, from the insurance carrier itself, that the device has met the safety standards of mechanical strength, rigidity and control the commissioner has established. Then it adds an outside inspection:

A certificate of examination by a person who possesses a certificate of competency to inspect amusement devices, issued under section 62A of chapter 146, and a certificate of liability insurance shall be furnished to the commissioner 10 days prior to the opening of the amusement device.

That inspector is not an employee of the park. M.G.L. c. 146, sec. 62A creates a separate state credential for amusement device inspectors, with a competency examination, a renewal cycle tied to the holder’s date of birth, and reexamination required of anyone who stops working as an inspector for a year or more.

The license itself runs one year, is valid throughout the Commonwealth, and can be revoked for cause. A traveling carnival carries one additional duty that is easy to check after the fact: it must notify the commissioner at least one month in advance of where it will be and on what dates.

For a family trying to understand what happened to them, the significance is not the licensing scheme in the abstract. It is that a licensed ride has a documented history sitting in a state file, and an unlicensed one has a violation.

What Counts as an Amusement Device, and What Does Not

The definition does most of the work in this area, and it is narrower than people expect. Section 205A opens with it:

As used in this section, the words ”amusement device” shall mean a mechanical ride or device constructed and designed to carry 1 or more persons for entertainment or amusement purposes and which is powered by means of internal combustion or electrical energy

Three elements. It is mechanical. It carries people. It runs on an engine or on electricity. A roller coaster, a ferris wheel, a carousel, a swing ride, a drop tower and a spinning teacup all satisfy that description without any argument.

The statute then carves two categories out expressly. It does not apply to recreational tramways, which M.G.L. c. 143, sec. 71I defines to include chair lifts, skimobiles and aerial passenger tramways, and which live in a different chapter with a different and much shorter deadline. It also does not apply to manually operated amusement rides with coined devices, which is the mechanical horse outside a supermarket.

One further provision keeps the definition from being the end of the inquiry. The section gives the commissioner discretion to further define an amusement device operated under it, and separately directs the commissioner to promulgate regulations on climbing wall safety. So the statute is the floor of the scheme rather than its ceiling, and whether a particular attraction has been pulled inside the licensing regime by regulation is a question to be answered for that attraction rather than assumed.

Trampoline Parks and Bounce Houses Sit Outside the Definition

This is a place where an honest answer is more useful than a confident one.

A trampoline court is not a mechanical ride. It is not powered by internal combustion or electricity, and it does not carry anyone anywhere. On the words of the statute it is not an amusement device, and no provision of sec. 205A names trampoline parks. An inflatable bounce house has an electric blower holding it up, but the blower does not carry riders, and the section does not name bounce houses either.

The one inflatable the Legislature did address is a climbing wall, and it addressed it carefully:

No license to operate a portable fabricated rock climbing wall, including an inflatable wall, with a height in excess of 12 feet shall be granted nor shall such a rock climbing wall be operated unless all climbers are fitted with a safety harness and a belay safety system is used with each climber and operated by persons trained in the proper use of such system.

The same paragraph requires an inflatable wall over 12 feet to have an inflatable protective base and a guardrail around it, and forbids any operator from letting a person use a wall over 12 feet without protective headgear. Tall climbing walls are regulated in detail. Trampoline courts and bounce houses, on the face of the statute, are not.

That does not make a trampoline park claim weaker. It means the claim runs on different rails. It becomes a premises liability case about how the facility was staffed, supervised, maintained and loaded, governed by the ordinary duty of care described further down, and it usually arrives with a signed release attached to it. The guide to liability waivers in Massachusetts sets out where that signature stops working, and the premises liability guide covers the notice and hazard questions that decide most of these cases. If equipment failed rather than supervision, the warranty route described in the defective product guide is often the stronger theory.

The 48 Hour Rule

For a ride that is an amusement device, sec. 205A contains the most useful sentence in this corner of Massachusetts law, and it fires without anyone requesting it:

If an injury requiring medical treatment has occurred on such an amusement device, reasonably due to a defect or malfunction in the amusement device, or if the amusement device constitutes a hazard to life, limb or property, as determined by the commissioner or his designee or by an agent of the insurance carrier, the amusement device shall be closed immediately and, within 48 hours, the owner or operator shall notify the commissioner or his designee in writing upon a form approved by the commissioner and the insurance carrier.

Look at what that creates. A written report, on a state form, filed within two days of the injury, by the party with the most to lose from writing it down. The ride cannot reopen until the repairs satisfy both the commissioner and the insurance carrier, which means a repair record exists as well. And the statute does not leave the investigation to the park:

All such injuries shall be investigated by inspectors in the division of inspection.

The licensee pays for that investigation by the inspector hour. So in the days after a serious ride injury, while a family is still in a hospital, a state investigation is supposed to be underway, producing documents that no defendant controls. Those records are often the difference between a case built on memory and a case built on paper, and like all records they are easier to obtain early than late.

The Log Nobody Thinks to Ask For

The second records provision is quieter and, in a contested case, frequently worth more:

An owner and an operator of an amusement park or amusement device shall each maintain and preserve a log of all regular maintenance schedules, service and repair reports, periodic inspections performed and any accident or injury which may have occurred on an amusement device, which shall be made available upon request to an inspector in the office of public safety and inspections of the division of occupational licensure.

Two logs, kept by two different parties, covering four categories: scheduled maintenance, service and repair, periodic inspections, and prior accidents. A ride that hurt someone in July and hurt someone else in August should appear twice in that log, and a defense built on the idea that nothing like this had ever happened before has to survive it.

The statute stacks inspection duties on top of the log. Owners of permanent or traveling amusement parks must comply with the American Society for Testing and Materials standards on amusement rides and devices, and must conduct daily inspections of amusement devices by both ride operators and trained maintenance personnel. Devices at permanent parks must be inspected annually by a certified inspector. Every park must keep at least one person on staff certified by the commissioner as qualified to oversee operation, maintenance and inspection, must employ full time emergency medical personnel, and must maintain ambulance services within the park.

None of that is a promise that a given park complied. It is a list of the specific things an injured person is entitled to ask about, phrased the way the law phrases them. Preserving evidence early matters here for the same reasons set out in the guide to social media and injury claims, and the same caution applies to what gets said to the other side, which the recorded statement guide covers.

A Million Dollars Is the Floor, and It Is a Licensing Condition

The statute sets a minimum that surprises people who assume a traveling carnival has nothing to collect from. The operator of a permanent or traveling amusement park must furnish the commissioner proof that all amusement devices in the park are covered for at least $1,000,000 for combined single limit bodily injury and property damage. Proof may take the form of insurance from a carrier approved to do business in the Commonwealth, or a bond, security or other indemnity providing substantially equivalent coverage.

The section also polices lapses. If the policy expires or is cancelled, the carrier must notify the commissioner at least 10 days before termination, the ride must close no later than the termination date, and it stays closed until insurance is obtained. A ride running without coverage is operating in violation of its license. That is a fact about the business rather than about any particular accident, but it bears directly on who can actually pay a claim.

Breaking the Statute Is Evidence, Not an Automatic Win

It would be convenient if proving a violation ended the argument. In Massachusetts it does not, and any page suggesting otherwise is selling something. The Supreme Judicial Court set out the rule in Perry v. Medeiros, 369 Mass. 836 (1976), quoting its earlier decision in Dolan v. Suffolk Franklin Savings Bank, 355 Mass. 665 (1969):

The general rule in Massachusetts is that violation of the safety statute or ordinance does not in itself give rise to a cause of action but is evidence of negligence.

Perry went on to describe how far that evidence reaches, again quoting older authority: a violation “is evidence of negligence on the part of a violator as to all consequences that the statute, ordinance or regulation was intended to prevent.” An inspection rule written to keep a restraint from opening in mid cycle is evidence in a case about a restraint that opened in mid cycle.

The criminal penalty in sec. 205A points the same way. Whoever violates the section may be fined not more than $1,000 or imprisoned for not more than one year, or both. That penalty is paid to the Commonwealth, not to an injured rider. What the statute gives a claim is the duties it fixes and the records it forces into existence.

Why a Signed Release Does Not Answer the Statutory Question

Massachusetts enforces pre-injury releases of ordinary negligence more readily than many states do, and anyone hurt at a recreational business should expect the release to be the first thing the defense raises. The waivers guide walks through when that signature holds and when it does not.

One limit matters here specifically. In Henry v. Mansfield Beauty Academy, Inc., 353 Mass. 507 (1968), the Supreme Judicial Court accepted that a customer “could make a valid contract exempting the defendant from liability to her for injuries resulting from its negligence or that of its employees”, and then drew the boundary:

But such a contract cannot serve to shield the defendant from responsibility for violation of a statutory duty.

The Appeals Court restated the same principle in Gonsalves v. Commonwealth, 27 Mass. App. Ct. 606 (1989). Where sec. 205A applies, its duties bound the business before anyone reached the ticket window, and they are not the kind of thing a customer can sign away at the gate. That is precisely why the line between a licensed powered ride and an unregulated trampoline court is worth establishing at the outset rather than at the end.

The Duty That Applies Even Where No Statute Does

For every attraction the Legislature has not addressed, Massachusetts still imposes one unified standard on the business that invited you in. In Mounsey v. Ellard, 363 Mass. 693 (1973), the Supreme Judicial Court discarded the old categories:

Therefore, we no longer follow the common law distinction between licensees and invitees and, instead, create a common duty of reasonable care which the occupier owes to all lawful visitors.

The Court described the resulting standard as reasonable care in all the circumstances, and quoted the underlying formulation: a landowner “must act as a reasonable man in maintaining his property in a reasonably safe condition in view of all the circumstances, including the likelihood of injury to others, the seriousness of the injury, and the burden of avoiding the risk.”

For a trampoline park, that is the entire case. How many jumpers were on a court built for how many. Whether a monitor was watching, and whether that monitor had any authority to stop anything. Whether the pads between the trampolines were in place and intact. Whether a foam pit was maintained at depth or had compacted into a floor. Whether the facility’s own posted rules were enforced by anyone at all. None of those are statutory questions in Massachusetts. All of them are negligence questions, and a jury is allowed to answer them.

Ski Lifts and Town Fairs Are Governed Somewhere Else

Two adjacent settings look like amusement rides and are not treated as amusement devices. Getting this wrong costs cases outright.

The first is the ski area. Section 205A expressly does not apply to recreational tramways as defined in M.G.L. c. 143, sec. 71I, a definition that sweeps in chair lifts, skimobiles, and two car and multi car aerial passenger tramways. Those claims live in c. 143, secs. 71H to 71S, and sec. 71P is a trap for the unwary. It requires notice by registered mail within 90 days of the incident on an injury to a skier, and it provides that “An action to recover for such injury shall be brought within one year of the date of such injury.” One year, not three.

The second is public land. A ride at a town fair on municipal property, or an attraction run by a public body, brings the Massachusetts Tort Claims Act into play, with a written presentment step that has to happen before a complaint is filed. The guide to suing a city or town covers that sequence, and the swimming pool and drowning guide covers the closely related recreational water setting. If nobody charged admission, the recreational use statute may raise the standard from negligence to wilful, wanton or reckless conduct, which is a question worth answering before any others.

Proving a Case When the Operator Holds the Evidence

Ride cases carry an evidence asymmetry that ordinary crashes do not. The machine belongs to the defendant. The maintenance history belongs to the defendant. The employee who last checked the restraint works for the defendant. The rider was strapped into a seat and often could not see the mechanism that failed.

Massachusetts does not require an injured person to solve the engineering puzzle completely. In Coyne v. John S. Tilley Co., 368 Mass. 230 (1975), a case about a ladder that gave way in ordinary use, the Supreme Judicial Court restated the standard while quoting Jankelle v. Bishop Industries, Inc., 354 Mass. 491 (1968):

The plaintiff need not exclude every possible cause for his injuries. He is only required to show a greater likelihood that his injury was caused by the defendant’s negligence than by some other cause.

That is a real standard rather than a generous one, and Coyne itself came out against the plaintiff on its facts. But it does mean the question is comparative rather than absolute, and it is exactly why the statutory records described above carry so much weight. A maintenance log showing three service calls on the same restraint in a single season does more to establish a greater likelihood than any volume of argument about what probably happened.

Children, and the Rule About Who May Run the Ride

Amusement injuries land on children more often than on adults, and the statute contains one provision aimed squarely at that. No minor may operate an amusement device. A park that put a sixteen year old on the controls of a ride has violated the section, and that violation is evidence of negligence under the rule described above.

A hurt child’s claim also resolves differently from an adult’s. A settlement for a minor in Massachusetts generally requires court approval before it becomes final, and the process has its own participants and its own protections for the child. That sequence is set out in full in the guide to settling a child’s injury claim.

Fault, Deadlines and What a Case Is Worth

Amusement operators argue rider conduct, and they argue it aggressively: you unbuckled, you stood up, you ignored the height sign, you jumped into an occupied landing zone. Massachusetts handles that through comparative fault under M.G.L. c. 231, sec. 85, which reduces recovery in proportion to the injured person’s share of the negligence and bars recovery only where that share is greater than the total negligence of the parties being sued. The mechanics are covered in the comparative negligence guide.

The same statute closes a door operators would very much like to keep open:

The defense of assumption of risk is hereby abolished in all actions hereunder.

Buying a ticket to a thrill ride is not consent to be hurt by a defective one. An operator may argue about what a rider did. It may not argue that the rider accepted the risk of the operator’s own negligence.

On timing, the ordinary deadline is three years from the injury under M.G.L. c. 260, sec. 2A, which provides that tort actions “shall be commenced only within three years next after the cause of action accrues.” The exceptions above change that: one year for a ski area tramway, and a presentment step for a public defendant. The statute of limitations guide covers the general rule and the situations that shorten it.

Ride injuries also skew severe. Head and spine injuries are common in ejection and restraint failure cases, and each carries its own valuation problems, addressed in the traumatic brain injury guide and the spinal cord injury guide. What a lawyer costs in a case like this is set out in the fee guide. Where the injured person was working at the fair or the park rather than visiting it, the analysis shifts to the construction and workplace injury guide and the workers compensation system it describes.

What This Article Does Not Decide

Three limits are worth stating plainly rather than papering over.

First, sec. 205A delegates real substance to the commissioner, including discretion to further define an amusement device and a direction to promulgate climbing wall regulations. The regulations, not the statute, hold many of the technical standards a contested case turns on. Everything described above is drawn from the statute as published by the Legislature. The regulatory layer has to be checked for the specific attraction in question rather than inferred from the statute alone.

Second, no Massachusetts appellate decision construing sec. 205A turned up in the case law searched for this article. The section is clear on its face, but a reader should understand that its application to any particular ride has not been mapped by the appellate courts the way premises liability and waiver law have been.

Third, whether a particular park held a license, filed the 48 hour report, kept the log or carried the required coverage is a factual question that only a records request will answer. The statute says what the law requires of an operator. It does not promise that any given operator complied.

Frequently Asked Questions

Q: Does Massachusetts inspect amusement rides?

A: Yes, for powered mechanical rides. M.G.L. c. 140, sec. 205A requires a license from the commissioner of the division of occupational licensure before anyone may “operate or cause to be operated a ferris wheel, carousel, inclined railway or similar amusement device”. Before the ride opens, the commissioner must receive a certificate of examination from a person holding a certificate of competency to inspect amusement devices under M.G.L. c. 146, sec. 62A, along with a certificate of liability insurance, and both must arrive 10 days before opening. At a permanent amusement park, the statute adds that amusement devices shall be inspected annually by a certified inspector, on top of daily inspections by ride operators and trained maintenance personnel.

Q: What has to happen after someone is hurt on a ride?

A: Three things, and none of them are optional. Section 205A provides that if an injury requiring medical treatment has occurred on an amusement device, reasonably due to a defect or malfunction, the device “shall be closed immediately and, within 48 hours, the owner or operator shall notify the commissioner or his designee in writing upon a form approved by the commissioner and the insurance carrier.” The ride then stays closed until the repairs satisfy both the state and the insurance carrier. And the statute provides that “All such injuries shall be investigated by inspectors in the division of inspection.” A state investigation file may therefore exist before anyone in the family has called a lawyer.

Q: Is a trampoline park covered by the amusement device statute?

A: Usually not, and the reason sits in the definition. Section 205A defines an amusement device as “a mechanical ride or device constructed and designed to carry 1 or more persons for entertainment or amusement purposes and which is powered by means of internal combustion or electrical energy”. A trampoline court is not powered and does not carry riders, so on the statute’s own words it falls outside that definition, and no provision of the section names trampoline parks. The section does give the commissioner discretion to further define an amusement device, and it separately regulates tall rock climbing walls including inflatable ones. Outside those provisions a trampoline park injury is an ordinary premises liability claim, usually complicated by the release the facility requires at the door.

Q: Does the statute say anything about inflatables?

A: It addresses one inflatable in detail, a climbing wall taller than 12 feet. Section 205A provides that no license shall be granted for a portable fabricated rock climbing wall, including an inflatable wall, over 12 feet “unless all climbers are fitted with a safety harness and a belay safety system is used with each climber and operated by persons trained in the proper use of such system”. An inflatable wall over 12 feet must also be equipped with “an inflatable protective base and guardrail surrounding the base of the wall”, and no operator may let anyone use a wall over 12 feet without protective headgear. An ordinary bounce house is not addressed by name anywhere in the section.

Q: Is there a maintenance record I can ask for?

A: The statute requires one. It provides that an owner and an operator of an amusement park or amusement device “shall each maintain and preserve a log of all regular maintenance schedules, service and repair reports, periodic inspections performed and any accident or injury which may have occurred on an amusement device”, and that the log shall be made available upon request to an inspector in the office of public safety and inspections. That is two separate logs, held by two separate parties, covering repairs and prior accidents on the same ride. Whether a particular operator actually kept one is a factual question, but the duty to keep it is not in doubt.

Q: How much insurance does an amusement park have to carry?

A: At least $1,000,000. Section 205A requires the operator of a permanent or traveling amusement park to furnish the commissioner proof that all amusement devices in the park “are covered for an amount of at least $1,000,000 for combined single limit bodily injury and property damage”. Coverage is not merely prudent for these businesses, it is a condition of holding the license. The same section requires the carrier to warn the state at least 10 days before a policy lapses, and the ride must close no later than the termination date and stay closed until insurance is obtained.

Q: If the park broke the statute, do I automatically win?

A: No. Massachusetts treats a safety statute violation as evidence a jury may weigh, not as automatic liability. The Supreme Judicial Court stated it in Perry v. Medeiros, 369 Mass. 836 (1976), quoting Dolan v. Suffolk Franklin Savings Bank, 355 Mass. 665 (1969): “The general rule in Massachusetts is that violation of the safety statute or ordinance does not in itself give rise to a cause of action but is evidence of negligence.” The penalty in sec. 205A runs to the Commonwealth rather than to an injured rider, at a fine of not more than $1,000 or imprisonment for not more than 1 year, or both. The statute matters because it fixes duties and forces records into existence, not because it decides the case.

Q: I signed a waiver at the gate. Is my claim over?

A: Not necessarily, and the statute is one reason why. Massachusetts does generally enforce a signed release of ordinary negligence for a voluntary recreational activity, so a waiver is a serious obstacle rather than a formality. But a release has never been allowed to erase a duty the Legislature imposed. In Henry v. Mansfield Beauty Academy, Inc., 353 Mass. 507 (1968), the Supreme Judicial Court accepted that a customer could validly contract away ordinary negligence claims and then drew the line: “But such a contract cannot serve to shield the defendant from responsibility for violation of a statutory duty.” The Appeals Court restated the principle in Gonsalves v. Commonwealth, 27 Mass. App. Ct. 606 (1989). Where sec. 205A applies, the duties it imposes were binding before anyone reached the ticket window.

Q: Can the park argue I assumed the risk of a thrill ride?

A: Not as a defense that ends the case, because Massachusetts abolished it. M.G.L. c. 231, sec. 85 provides that “The defense of assumption of risk is hereby abolished in all actions hereunder.” The same section keeps ordinary comparative fault in play, reducing recovery in proportion to the injured person’s share of the negligence and barring recovery only where that share is greater than the total negligence of the parties being sued. So an operator can still argue that a rider ignored a restraint instruction. It cannot argue that buying a ticket to a roller coaster was consent to be hurt by a defective one.

Q: What if the ride was a chairlift or a ski area tramway?

A: Then a different chapter governs and the deadline is far shorter. Section 205A expressly provides that it “shall not apply to recreational tramways, as defined by section 71I of chapter 143”, and that definition covers chair lifts, skimobiles and aerial passenger tramways. Those claims run under M.G.L. c. 143, secs. 71H to 71S. Section 71P requires notice by registered mail within 90 days on an injury to a skier and provides that “An action to recover for such injury shall be brought within one year of the date of such injury.” One year rather than three, which means the identity of the ride decides the calendar.

Q: How long do I have to bring an amusement ride injury claim in Massachusetts?

A: For an ordinary amusement device claim, three years from the injury under M.G.L. c. 260, sec. 2A, which provides that tort actions “shall be commenced only within three years next after the cause of action accrues”. Two situations change that. If the ride was at a fair on municipal land or run by a public body, the Massachusetts Tort Claims Act adds a written presentment step that has to happen before a complaint is filed. If the device was a ski area tramway, the one year period in c. 143, sec. 71P applies instead. A child’s claim carries its own rules, both on timing and on the court approval needed to settle it.
