What a Dooring Accident Lawyer Proves

A dooring crash happens in an instant and through no fault of the person hit. You are riding along the edge of the road or in a bike lane, doing everything right, when someone in a parked car throws a door open directly into your path. There is no time to react. The impact throws you into the door or over the handlebars and often into the travel lane, and the injuries can be severe. Riders are frequently told afterward that they should have seen it coming or should not have been so close to the parked cars. Massachusetts law says otherwise.

The Commonwealth has a specific law about opening car doors, and it puts the responsibility squarely on the person who opens one. A driver or passenger may not open a door into traffic unless it is reasonably safe to do so, and the law is explicit that a cyclist being to the right of traffic is not a defense for the person who caused the crash. That makes dooring one of the clearer liability cases on the road, yet insurers still resist them, especially when the door was opened by a passenger, a rideshare rider, or a delivery driver rather than the vehicle’s operator.

Winning still takes proof. Who opened the door, whether it was the driver or a passenger, which company the vehicle was working for, and the position of the bike and the door all matter, and that information can slip away quickly if no one gathers it at the scene. Identifying the right responsible parties and their insurers early is often what separates a full recovery from a partial one.

None of that should fall on an injured cyclist alone. Bringing in a lawyer early means the investigation, the identification of everyone responsible, and the pressure from the insurer all become the firm’s responsibility rather than yours.

Dooring is more common than most drivers realize, and more dangerous. On a street lined with parked cars, a cyclist riding a safe, legal line still passes within the arc of dozens of doors, any one of which can swing open without warning. A driver or passenger who steps out without looking treats the bike lane as empty space, and the rider pays for that assumption. Understanding that dynamic is part of why these cases are framed correctly from the start: the rider was not in the wrong place; the door was opened at the wrong time.

Our firm handles these cases with that in mind. Larson Law is led by attorney Daniel J. Larson, a Boston personal injury attorney who treats a dooring as the clear violation it usually is, and who identifies every responsible party and preserves the proof before it disappears.

How the Door-Opening Law Protects You

A dooring claim is built on one of the clearest rules of the road in Massachusetts, together with the general fault and threshold rules that shape every injury case.

The door-opening law. Under G.L. c. 90, § 14, no person may open a door on a motor vehicle unless it is reasonably safe to do so without interfering with the movement of other traffic, including bicyclists and pedestrians. Opening a door into a rider’s path breaks that law, and a violation is strong evidence of negligence. Why it matters: this statute names the exact conduct that causes a dooring, which is why liability in these cases is usually clearer than in an ordinary crash, and it applies to whoever opens the door, driver or passenger alike.

Being to the right is not a defense. The same law states plainly that it is not a defense for a motorist causing a crash with a bicycle that the bicycle was to the right of vehicular traffic. Why it matters: insurers love to argue that a cyclist should not have been riding along the parked cars or in the door zone, and this language takes that argument away, protecting riders who were exactly where they were entitled to be.

Who is responsible. The person who opened the door is liable whether they were the driver or a passenger, and when the door was opened by someone acting for a business, a rideshare passenger, a delivery driver, a commercial operator, that company’s insurance may also apply. Why it matters: identifying every responsible person and policy is what makes a recovery whole, especially when a serious injury exceeds a single driver’s coverage.

Comparative fault, the threshold, and the deadline. Under G.L. c. 231, § 85 you can recover as long as your share of fault is not greater than the other side’s, reduced by your percentage; under G.L. c. 231, § 6D you may pursue pain and suffering once reasonable medical bills exceed two thousand dollars or the injury is a fracture, permanent, or fatal; and under G.L. c. 260, § 2A you generally have three years to sue. Why it matters: the door law makes fault clear, the threshold is easily met by real cycling injuries, and the clock runs while witnesses and details fade.

Put together, a dooring case usually starts with the law already on the rider’s side. The statute defines the violation, forecloses the favorite defense, and reaches whoever opened the door. What remains is proving who that was and documenting the full harm, both of which reward acting quickly.

Coverage can come from more than one place. The vehicle owner’s policy, a rideshare or delivery company’s policy where a passenger opened the door, and your own underinsured-motorist coverage can each apply. In a serious dooring, identifying every source of recovery early is often what makes the recovery match the harm.

The rise of rideshare and delivery traffic has changed the dooring landscape. A passenger flinging open a rear door to step out of a rideshare, or a delivery driver hopping out into a bike lane, causes a growing share of these crashes, and those situations can bring a company’s insurance into play alongside the individual’s. Sorting out whether the vehicle was on a trip, who the occupant was working for, and which policies were in force at that moment is detailed work, but it can be the difference between a claim limited to a single driver’s minimum coverage and one backed by a commercial policy large enough to meet a serious injury.

Dooring Accident Lawyer Serving Massachusetts

From our Boston base we represent cyclists and others hurt in dooring crashes across the Commonwealth. Dooring is a city problem above all, concentrated on the busy, parked-lined streets of Greater Boston where bike lanes run beside a wall of parked cars, but it happens anywhere people park and ride, from the town centers of the South Shore to the mill cities of the north and the streets to the west. Wherever it happened, the same door-opening law and the same evidence-first approach apply.

We handle these crashes as a Boston bicycle accident lawyer for the riders most often doored, and as a Boston pedestrian accident lawyer when a swung-open door strikes someone on foot, because the same statute protects both. That work reaches well beyond the city, including the cases a Cambridge personal injury lawyer handles just across the river, where dense streets and heavy cycling make dooring especially common.

A dooring crash also rarely produces a single kind of harm, because a cyclist has no protection at all. The impact and the fall drive much of your pain and the lasting disruption it leaves behind, they can cause the kind of life-altering, permanent injury that follows being thrown into traffic, and at their worst they take a life, leaving a family to pursue everything a wrongful death costs them. We make sure each of those dimensions is valued.

Where the crash happened also shapes the proof. A city street may be watched by a municipal or business camera that captured the door swing; the responding police report may identify the vehicle and its occupants; the position of the bike and the damage to the door tell their own story. Knowing which agency responded, which cameras exist, and which court will hear the claim is part of building it, and prompt action is often what identifies a passenger or a rideshare occupant before they are gone.

Wherever the case arises, the standard does not change. We represent doored riders from the bike lanes and parked-lined streets of Greater Boston to the town centers of central and western Massachusetts, with the same insistence on naming every responsible party and preserving the proof everywhere. A serious dooring deserves that rigor no matter where it happened, and no matter how an insurer tries to blame the rider for being on the road at all.

The geography of dooring is unusually specific. It concentrates exactly where bike lanes run beside continuous parking, on the commercial spines of Boston, Cambridge, and Somerville, along the older streets of the inner suburbs, and in any downtown where cars park at the curb and cyclists share the edge of the road. Those same streets tend to have cameras, on buildings, on buses, at intersections, that may have captured the door swing, but that footage is short-lived. Moving quickly to find it, and to identify the people in the car, is often what turns a strong dooring case into a proven one.

For a doored rider, the practical lesson is simple and urgent. The law will likely be on your side, but the facts that prove your case, who opened the door, who they were with, and whether a camera caught it, live at the scene and in the hours just after it. Those facts do not wait for you to recover. The most valuable thing an injured cyclist can do, once the immediate medical needs are met, is to get someone working on the case quickly, so that the strong legal position the door law provides is matched by the evidence needed to enforce it in full.

Thrown from the bike with nothing to protect them, a doored rider often suffers broken bones and other fractures that take months to heal.

What a Dooring Crash Really Costs You

A dooring crash is easy for an insurer to minimize and hard for the injured rider to overstate. The cost of being thrown from a bike reaches far past the first hospital bill, and a full claim means proving each layer of it.

The medical picture. A cyclist has nothing between them and the door or the pavement, so these crashes cause serious injuries, fractures, head and facial trauma, shoulder and wrist damage, and the injuries that follow being thrown into a travel lane, often requiring surgery and long rehabilitation. We gather the complete medical record and the treating opinions so the diagnosis, the cause, and the prognosis are documented rather than argued.

The work and earning picture. Injuries this serious frequently keep people out of work for months or end a career. We show how they limit what you can do and where they support a claim for lost wages and diminished future earning capacity, not just the paychecks already missed.

The daily and future picture. Chronic pain, disability, future surgeries and care, and the loss of the life and the riding you had before are real damages that must be valued now rather than after the fact. We tie each to evidence and, where the stakes justify it, bring in medical and vocational experts.

Naming every responsible party. Because a door can be opened by a driver, a passenger, or someone working for a rideshare or delivery company, part of the value of a dooring case lies in identifying everyone at fault and every policy that applies. We do that work early, so a serious injury is not left underinsured because a passenger or a company was never pursued.

It is worth knowing what to avoid, too. Do not let the scene clear before the occupants of the parked car are identified, and do not accept the suggestion that you were at fault for being near the parked cars, because the law says otherwise. Do not give a recorded statement or accept a quick settlement before everyone responsible is identified and your injuries are understood. We handle the insurer’s questions so an offhand remark never becomes the centerpiece of the defense against you.

Finally, a dooring case rewards moving quickly. The occupant who opened the door, any rideshare or delivery connection, and the video that shows the swing can all be identified in the days after the crash and lost soon after. We do that urgent work immediately and then build the case fully, so that when the time comes to negotiate, the demand rests on a clear violation, the right defendants, and a complete medical picture.

What ties all of this together is that a dooring case is usually strong on liability and only lost through delay. The law is on the rider’s side, the favorite defense is foreclosed, and the fault is clear, but none of that helps if the occupants of the car are never identified, the video is overwritten, or the deadline slips by. Our role is to make sure none of that happens: to lock down who opened the door and who they were working for, to preserve the proof, and to build the medical picture fully, so that a case the law already favors becomes a recovery that reflects the real cost of the crash.

None of this is about blame for riding; it is about making the protection the law already provides real, and that is exactly the work we take on for every doored rider we represent.

Questions Cyclists Ask Us Most

What is a dooring crash?

A dooring crash happens when a driver or passenger opens a car door into the path of a passing cyclist, motorcyclist, or pedestrian. The person hit has no time to react and is thrown into the door or over the handlebars, often into the travel lane. Under Massachusetts law it is usually the fault of whoever opened the door.

Almost always the person who opened the door. Under G.L. c. 90, § 14, no one may open a car door unless it is reasonably safe without interfering with other traffic, including bicyclists and pedestrians. Opening a door into a rider’s path violates that law and is strong evidence of negligence.

Yes. The law applies to whoever opens the door, not only the driver. A passenger who swings a door into a bike lane is responsible for the crash, and if that passenger was in a rideshare or working for a delivery service, that company’s insurance may also apply to your claim.

No, and the law is explicit. G.L. c. 90, § 14 says it is not a defense that the bicycle was to the right of vehicular traffic. Insurers still raise the argument, but the statute takes it away, protecting riders who were exactly where they were allowed to be.

Then the case may reach more than one insurer. If the person who opened the door was a rideshare passenger or a delivery driver, the company connected to that trip may share responsibility along with the individual. These cases take extra work to untangle, which is why identifying the vehicle’s purpose and occupants early matters so much.

Usually, yes. Under G.L. c. 231, § 6D, a crash victim can seek pain and suffering once reasonable medical bills exceed two thousand dollars or the injury is a fracture, permanent, or fatal. The serious injuries a cyclist suffers in a dooring almost always clear that threshold, opening a full claim beyond any no-fault benefits.

That argument usually fails here. Under G.L. c. 231, § 85 you can still recover unless you were more than half at fault, and the door-opening law says being to the right of traffic is no defense for the person who doored you. The fault in these cases sits overwhelmingly with whoever opened the door.

Generally three years from the date of the crash under G.L. c. 260, § 2A. But the details that identify who opened the door, especially a passenger or a rideshare occupant, can vanish within days. Contacting a lawyer immediately protects both the legal deadline and the proof of who was responsible.

Then the family may bring a wrongful death claim against whoever opened the door and any company responsible for that person. The same door-opening law and the same protections apply, with far higher stakes. We handle these claims with care for the family while pursuing full accountability for a preventable loss.

If you are able, get the names of the driver and any passengers, note who opened the door, and identify whether the car was a rideshare or delivery vehicle. Photograph the door, the bike, and the position of both, and get any witnesses. Then get medical care right away.

Nothing up front. We handle dooring and other cycling cases on a contingency fee, so you pay no attorney fee unless we recover for you, and the first consultation is always free and confidential. That lets you get the crash investigated and every responsible party identified with no financial risk during a hard time.

Attorney Daniel J. Larson leads the firm and stays personally involved in the cases we take. You will work with a lawyer who knows the door-opening law and how to trace every responsible party, not just a file number, and who builds your dooring claim with the proof and the right defendants it needs.
