Can New York City Be Liable for a Dangerous Street or Intersection?
When a pedestrian, bicyclist or motorist is seriously injured in a New York City traffic accident, the investigation should not always end with the drivers involved. In some cases, the design, operation or maintenance of the roadway itself may have contributed to the crash.
New York City has a duty to maintain its streets in a reasonably safe condition. Although municipalities receive qualified immunity for certain roadway and traffic-planning decisions, that protection is not absolute. Where the City knew of a dangerous condition, failed to adequately study it, or unreasonably delayed implementing an identified safety improvement, municipal liability may be possible.
Why a History of Accidents Matters
The new list of New York City’s most dangerous streets raises an important question after a serious accident: Did the City already know the location was dangerous?
The fact that an accident occurred on Northern Boulevard, Atlantic Avenue, Jerome Avenue, 125th Street or another “Boulevard of Death” does not automatically make the City liable. However, a history of similar crashes may be important evidence.
An investigation should determine whether NYC DOT had received prior complaints, studied the location, identified a dangerous traffic pattern or recommended safety improvements.
Relevant records can include prior crash data, traffic and pedestrian studies, speed studies, signal-timing records, complaints, roadway-design plans and proposed safety improvements.
The New York Court of Appeals has held that municipal traffic-planning immunity depends upon an actual reasoned planning process. The City also has a continuing obligation to review a traffic plan in light of how it operates in practice.
What If the City Identified the Danger but Failed to Fix It?
This can be particularly important when NYC DOT has already identified a safety problem and recommended an improvement.
If the City determined that an intersection needed a new traffic signal, pedestrian island, altered signal timing, protected bicycle lane, lane reduction or another safety measure, the investigation should ask:
When did the City identify the danger, what did it propose to do, and how long did it wait to do it?
An unreasonable delay in implementing an already-approved safety plan may potentially support a claim against the municipality.
Roadway Defects Are Different
Accidents caused by a pothole, broken pavement, sunken manhole or other physical roadway defect can involve different legal requirements, including New York City’s prior-written-notice law and its recognized exceptions.
This distinction matters. A claim involving negligent roadway design or traffic planning may be very different from one involving a physical defect in the street.
Claims Against NYC Require Prompt Investigation
Claims against the City are also subject to special procedural requirements. In many personal-injury cases, a Notice of Claim must generally be served within 90 days.
After a serious pedestrian or bicycle accident, an attorney should therefore move quickly to preserve surveillance footage and obtain NYC DOT records, accident histories, traffic studies, complaints, roadway plans and records of proposed safety improvements.
The “Boulevards of Death” study does not prove that New York City is responsible for every crash on one of these streets. But when someone is seriously injured on a roadway with a documented history of crashes, the investigation should look beyond the individual driver and ask:
Was this a known dangerous location? Had similar accidents happened before? Did NYC DOT study the problem? Were safety improvements recommended but never implemented?
The answers may help determine whether a serious NYC pedestrian or bicycle accident involves not only driver negligence, but also a potential claim arising from the design, operation or maintenance of the roadway itself.
