When a driver struck and killed 12-year-old Sammy Cohen Eckstein in a Brooklyn crosswalk in 2013, his death became a catalyst for change in how New York approaches traffic safety. The driver was traveling 34 mph in a 30 mph zone near Prospect Park. Sammy's mother, Amy Cohen, channeled her grief into advocacy, and more than a decade later, that work resulted in legislation bearing her son's name.

Sammy's Law, signed by Governor Kathy Hochul in 2024, fundamentally changed how New York City can regulate vehicle speeds. The law gives the city authority to lower speed limits below the previous statewide minimums, something local officials had been requesting for years but lacked the power to implement. Understanding what this law does and how it affects road safety matters for anyone who lives, works, or travels in New York City — whether on foot, on a bike, or behind the wheel.
What Does Sammy's Law Actually Allow?
Before Sammy's Law, New York City was bound by state regulations that set a minimum default speed limit of 25 mph on city streets. Even if city officials believed lower speeds would save lives, they couldn't make those changes without state approval. Sammy's Law removed that barrier.
The legislation authorizes New York City's Department of Transportation (DOT) to lower the default speed limit for motor vehicles from 25 mph to 20 mph across the entire city. In areas identified as particularly high-risk, such as school zones or neighborhoods with heavy pedestrian traffic, the DOT can go even lower and set limits at 15 mph. These reduced limits must be paired with physical traffic-calming measures like speed bumps, narrowed lanes, or raised crosswalks to help enforce compliance and change driver behavior.
The law specifically targets motor vehicles. This distinction becomes important when looking at recent controversies about how the law has been applied, particularly in spaces like Central Park where cyclists, pedestrians, runners, and vehicles all share the road.
Why Speed Limits Matter for Pedestrian Safety
The physics of vehicle collisions are unforgiving. When a car traveling 25 mph strikes a pedestrian, the person has about a 75% chance of survival. At 30 mph, that survival rate drops dramatically; at 40 mph, most pedestrians die. Those few extra miles per hour translate directly into whether someone walks away from a crash or whether their family plans a funeral.
Speeding contributes to roughly one-third of all traffic deaths in New York City. Across New York State, traffic fatalities have climbed more than 30% in recent years, even as the total number of crashes has declined. That means when crashes happen, they're more severe and more deadly. In 2024 alone, New York saw over 1,000 traffic deaths.
Sammy's Law fits into a broader strategy called Vision Zero, which aims to eliminate all traffic deaths and serious injuries. The approach originated in Sweden and operates on the principle that no loss of life on roadways is acceptable or inevitable. Reducing vehicle speeds is one of the most effective tools in the Vision Zero toolkit because it gives drivers more time to react and reduces the force of impact when crashes occur.
How New York City Has Implemented the Law
After Governor Hochul signed Sammy's Law in 2024, the New York City Department of Transportation began planning how to roll out lower speed limits across the five boroughs. The citywide implementation of a 20 mph default speed limit requires coordination with infrastructure changes, new signage, and public education campaigns.
The DOT has also identified specific areas where 15 mph limits make sense. These include zones around schools where children cross streets multiple times a day, neighborhoods with high concentrations of elderly residents, and areas with documented histories of serious pedestrian crashes.
The law gives the DOT significant discretion in determining where and how to apply these lower limits, as long as they pair the speed reductions with physical changes to the street environment. Simply posting a new sign isn't enough; the city must demonstrate it's taking comprehensive steps to make streets safer.
The Central Park Controversy
In late 2025, the DOT announced plans to impose a 15 mph speed limit on Central Park's bike loop, applying the restriction to cyclists, e-bikes, e-scooters, and essential vehicles. The decision followed a 60-day community board review process and was framed as a safety measure to protect families, runners, and casual park users from faster-moving cyclists.
The announcement sparked immediate pushback from the cycling community. In February 2026, the New York Cycle Club, the city's oldest recreational cycling organization (founded in the 1930s), filed a lawsuit in Manhattan Supreme Court challenging the application of Sammy's Law to bicycles.
The lawsuit raises several legal arguments:
The club points out that Sammy's Law specifically authorizes speed limits for "motor vehicles," not bicycles or other non-motorized transportation. Applying the law to cyclists, they argue, exceeds the DOT's authority under the statute.
The club contends that the city bypassed required administrative procedures. If the DOT wanted to impose new speed limits on cyclists, it should have followed standard rulemaking processes that include public notice, hearings, and opportunities for comment. According to the lawsuit, the city misapplied a statute designed for cars and trucks.
The practical impact on cyclists has also become a point of contention. The New York Cycle Club includes competitive riders and recreational cyclists who use Central Park for training. Olympic gold medalist Kristen Faulkner prepared for her 2024 victories using the park's loop. Many serious cyclists ride early in the morning or in the evening when pedestrian traffic is lightest, following what the club calls its "Central Park Protocol" to minimize conflicts with other park users.
A January 2026 DOT report showed that cyclists only exceed 15 mph on average during early morning hours before 9 a.m. The report also noted that on downhill sections of the loop, cyclists reach speeds over 15 mph without pedaling, simply due to gravity. Requiring riders to brake constantly on descents creates its own safety issues and makes the park effectively unusable for any serious cycling.
DOT spokesperson Vincent Barone defended the policy, stating it "reduces confusion and promotes safety" by aligning with the 15 mph limits already in place for e-bikes on city streets. The city has indicated it plans to vigorously defend the rule in court.
The case is pending before Judge Nicholas Moyne in Manhattan Supreme Court. As of early 2026, it remained unclear whether the city would actively enforce the 15 mph limit against cyclists or wait for the legal challenge to resolve.
Does Sammy's Law Apply to Bicycles?
The Central Park dispute highlights a fundamental question about Sammy's Law. The statute authorizes lower speed limits for motor vehicles. Traditional bicycles are not motor vehicles under New York law; they're classified differently and subject to different regulations.
E-bikes and e-scooters occupy a more complicated space. They have motors, but they're not cars or motorcycles. New York law treats them as a distinct category of vehicle with their own rules. Whether Sammy's Law was intended to cover electric micromobility devices remains legally unclear.
The legislative history and public statements surrounding Sammy's Law focused almost exclusively on cars, trucks, and other traditional motor vehicles. The problem the law sought to address was drivers killing pedestrians. Bicycles, while they can cause injuries in collisions with pedestrians, represent a fundamentally different level of risk: a 3,000-pound vehicle traveling 30 mph carries exponentially more kinetic energy than a 200-pound cyclist and bike traveling the same speed.
This doesn't mean cyclists should disregard safety or that speed limits for bikes are necessarily inappropriate. It means that if the city wants to regulate bicycle speeds in parks or elsewhere, it likely needs to do so through proper channels designed for that purpose, rather than stretching a statute written to address motor vehicle crashes.
The Stop Super Speeders Act and Other Related Efforts
Sammy's Law is part of a broader push to address dangerous driving in New York. Another significant piece of legislation working its way through Albany is the Stop Super Speeders Act, which passed the State Senate in 2025 and remained pending in the Assembly.
This proposed law targets repeat offenders who accumulate 11 or more points on their license within 18 months or receive 16 or more speed camera tickets in a year. These drivers would be required to install Intelligent Speed Assistance (ISA) devices in their vehicles. The technology uses GPS and cameras to detect speed limits and prevents the car from traveling more than 5 mph over the posted limit.
The concept is similar to ignition interlock devices required for drunk driving offenses, but instead of testing for alcohol, the device limits speed. Installation costs around $150, with a daily operating fee of about $4. Governor Hochul's budget includes funding for a pilot program in New York City.
Amy Cohen, Sammy's mother and a prominent voice with Families for Safe Streets, testified in favor of the Stop Super Speeders Act in February 2026. She pointed to data showing that a small percentage of extremely reckless drivers cause a disproportionate share of serious crashes and deaths. About 75% of drivers with suspended licenses continue driving anyway, making suspensions alone an ineffective deterrent.
The Intelligent Speed Assistance approach attempts to physically prevent dangerous speeding rather than relying on the threat of penalties after the fact. Whether the technology proves effective and politically sustainable remains to be seen, but it represents the kind of innovative thinking that advocates argue is necessary to make meaningful progress on traffic safety.
What Happens If You're Hit by a Speeding Driver
If a driver exceeds the speed limit and causes a crash that injures you or kills someone you love, the fact that they were speeding matters significantly in any legal case. Speeding is a violation of traffic law, and violating traffic law is evidence of negligence.
In a personal injury or wrongful death case, your attorney will need to prove that the driver's negligence caused the crash and your injuries. Evidence that the driver was traveling 40 mph in a 20 mph zone makes that case much stronger than a situation where both parties were following all applicable rules and the crash resulted from an unavoidable accident.
Speed also affects the severity of injuries. Higher-speed crashes cause more devastating harm. That translates directly into larger medical bills, longer recovery times, more extensive permanent disabilities, and greater pain and suffering. All of these factors influence the compensation you may be entitled to recover.
New York operates under a no-fault insurance system for car accidents, which means your own insurance pays for your medical bills and lost wages up to certain limits regardless of who caused the crash. But no-fault coverage is limited. Once your injuries exceed the "serious injury" threshold defined in New York law, you can step outside the no-fault system and file a lawsuit against the at-fault driver.
Serious injuries include death, dismemberment, significant disfigurement, fractures, permanent loss of use of a body part or organ, permanent significant limitation of a body function or system, or an injury that prevents you from performing substantially all of your usual daily activities for at least 90 of the first 180 days after the crash.
If a speeding driver killed someone you love, you may be able to bring a wrongful death claim on behalf of the estate and surviving family members. These cases seek compensation for the deceased person's pain and suffering before death, medical expenses, funeral costs, and the losses suffered by surviving family members including lost financial support, lost services, and loss of companionship.
How Lower Speed Limits Could Affect Future Cases
As New York City implements lower speed limits under Sammy's Law, the legal landscape for traffic crash cases will shift. A driver traveling 25 mph might have been following the law under old rules but could now be speeding under the new 20 mph or 15 mph limits.
This creates stronger cases for injured pedestrians and cyclists. It also potentially increases the damages available, since evidence of a traffic violation can support claims for punitive damages in some circumstances, though New York law generally limits punitive damages in vehicle crash cases.
For drivers, the lower limits mean greater responsibility to pay attention to posted speeds and adjust behavior accordingly. The "I didn't see the sign" defense becomes harder to maintain when speed limits are widely publicized and accompanied by physical traffic calming measures that make higher speeds uncomfortable or impossible.
Insurance companies will also adjust their risk calculations. Areas with lower speed limits and traffic calming infrastructure should theoretically see fewer serious crashes, which could eventually affect insurance rates. In the short term, though, drivers caught speeding in new low-speed zones may face higher premiums after tickets or crashes.
What This Means for Different Road Users
Pedestrians: Sammy's Law represents a meaningful step toward safer streets. Lower vehicle speeds give pedestrians more time to cross intersections, make it easier for drivers to see them, and dramatically improve survival chances in a crash.
Cyclists: The law's intent clearly supports safety, but the Central Park controversy shows how implementation can become complicated. Cyclists benefit from slower vehicle speeds on streets, but applying motor vehicle regulations to bicycles creates confusion and potential conflicts.
Drivers: Sammy's Law requires adjusting to new speed limits and recognizing that city streets are shared spaces where pedestrian and cyclist safety takes priority over vehicle speed. The changes may feel inconvenient but modest speed reductions save lives without significantly affecting travel times for most trips.
Parents, older adults, and people with disabilities: Lower speed limits make navigating the city less dangerous. Children have more margin for error, and people using wheelchairs or walkers have more time to get across intersections.
The Bigger Picture of Vision Zero
Sammy's Law exists within the broader Vision Zero framework that guides New York City's approach to traffic safety. Vision Zero rejects the idea that traffic deaths are inevitable accidents and instead treats them as preventable through thoughtful street design, appropriate regulations, and cultural change around driving behavior.
The strategy includes multiple elements beyond speed limits:
Protected bike lanes that separate cyclists from vehicle traffic
Leading pedestrian intervals that give people on foot a head start at intersections
Daylighting to keep parked cars away from crosswalks so drivers and pedestrians can see each other
Speed cameras to automate enforcement in areas where police presence is inconsistent
Sammy's Law provides one crucial tool in this larger toolkit. Speed limits alone won't eliminate traffic deaths, but combined with infrastructure changes, enforcement, and public education, they contribute to a comprehensive approach that has proven effective in cities around the world.
New York City has seen progress under Vision Zero, with traffic deaths declining from historic highs in previous decades. But progress has been uneven, and recent years have seen troubling increases in fatalities. The work remains far from complete.

Summing It Up
Sammy's Law honors a child killed by a speeding driver by giving New York City the power to implement the kind of speed limits that evidence shows save lives. The law allows the city to lower default limits to 20 mph and create 15 mph zones in high-risk areas, paired with physical changes to streets that support safer driving.
The Central Park cycling controversy illustrates that implementing new safety measures can create unexpected conflicts and legal questions. Whether Sammy's Law applies to bicycles or only to motor vehicles will likely be resolved through the courts, clarifying how the city can regulate different types of road users.
For anyone injured by a speeding driver, the violation of posted speed limits strengthens legal claims and reflects the driver's negligence. As the city implements lower limits, the definition of safe and legal driving changes, potentially affecting future crash cases and how damages are calculated.
The law represents one part of a larger effort to make New York streets safer for everyone. Combined with other measures like the proposed Stop Super Speeders Act, protected infrastructure for pedestrians and cyclists, and continued advocacy from groups like Families for Safe Streets, these changes aim to prevent other families from experiencing the loss that Amy Cohen and her family endured when Sammy was killed.
Whether you walk, bike, or drive in New York City, Sammy's Law affects how you navigate the streets. The lower limits may require adjusting habits and expectations, but the goal is straightforward: getting everyone home safely matters more than getting there quickly.
