What is the speed limit in New York City?
The speed limit in New York City is 25 mph unless a sign shows a different number. NYC311 calls this the citywide limit for motorists, and the signs you pass read "NYC Law Speed Limit 25 unless otherwise posted."
The city lowered the default from 30 mph to 25 mph on November 7, 2014. Since then it has installed more than 8,400 speed limit signs, each with a note about photo enforcement.
Is the speed limit in NYC 25 or 30?
It is 25 mph. The old 30 mph default ended in 2014, so if you learned to drive here before then, your habits may be out of date. A posted sign can show a different limit, and the sign always wins.
What is the speed limit on NYC highways and parkways?
Follow the signs, because NYC311 gives no single number for highways. Statewide, the Insurance Institute for Highway Safety lists a maximum of 65 mph on New York interstates and other limited-access roads and 55 mph on other roads. Inside the city, the posted limit on an expressway or parkway can be lower than that maximum, so read each sign as you enter.
Where are the speed cameras in NYC?
NYC speed cameras are found only in school speed zones, which reach a quarter mile from a school building. State law authorizes 750 of those zones, and they are spread across all five boroughs.
NYC DOT had placed at least one camera in every one of the 750 zones by June 2020. It reported more than 2,200 cameras by the end of 2023, and the Governor's office put the number at more than 2,400 in June 2025. A quarter mile covers a lot of streets, so in practice a camera can sit on an ordinary avenue that does not look like a school street at all.
DOT chooses sites using speed data, the shape of the road and the crash history of the zone. It also uses both fixed and mobile camera units within these zones.
How did the NYC speed camera program grow?
The program started small. State lawmakers authorized a pilot in 20 school speed zones in 2013, and the first violation went out in January 2014. Six months later the pilot grew to 140 zones, and in 2019 the state authorized the current 750.
Are there speed cameras on New York highways and bridges?
There is a separate work zone program. New York's automated work zone speed enforcement runs through 2031 and now includes MTA Bridges and Tunnels and New York State Bridge Authority properties. The number of eligible work zones for the state transportation department and the Thruway Authority also doubled. For how New York compares with other states, see our guide to which states have speed cameras.
What hours do NYC speed cameras work?
NYC speed cameras work around the clock, every day of the year. The current hours took effect on August 1, 2022, and the state has since extended the program through July 1, 2030.
Before that date, cameras were limited to weekdays between 6 a.m. and 10 p.m. State lawmakers changed the rule after speeding and deaths rose during the pandemic, particularly overnight.
Do NYC speed cameras work at night and on weekends?
Yes, they work at night and on weekends, which can surprise drivers who remember the old schedule. An empty street at 2 a.m. on a Sunday gets the same treatment as a school run on a Tuesday morning.
Do NYC speed cameras work in summer?
Yes, they work through summer vacation and on school holidays, because the program runs year-round. School being closed changes nothing. For a state-by-state look at the hours elsewhere, read school zone speed cameras in the US.
How do you know a speed camera is ahead in NYC?
You know because every NYC speed camera is preceded by a speed limit sign with a reminder that the limit is photo enforced. DOT's advice is simple: stay at or below the limit wherever you are.
Three things help on an unfamiliar route:
- Look for the plate under the limit. A speed limit sign with a "Photo Enforced" panel is the standard reminder.
- Think about schools. If you can see a school, you are inside a zone that may have a camera, and you may be inside one even if you cannot.
- Treat 25 as the ceiling. With no other sign in view, 25 mph is the limit on city streets.
Because DOT also uses mobile units, the sign is the reliable clue on any given day.
What is Sammy's Law?
Sammy's Law is a state law, signed on May 9, 2024, that lets New York City lower speed limits to 20 mph on individual streets and to 10 mph on streets with added traffic calming. It is named for Sammy Cohen Eckstein, a 12-year-old who was killed by a van in October 2012 while retrieving a ball on Prospect Park West in Brooklyn.
In June 2024, DOT announced the first 60 locations, including areas around schools, high-crash corridors and a regional slow zone in each borough. The first of those regional zones covers Lower Manhattan below Canal Street, with its narrow, irregular streets.
Are NYC school zones changing to 15 mph?
Yes, the city is moving school locations to 15 mph in stages. On March 16, 2026, Mayor Zohran Mamdani and DOT Commissioner Mike Flynn announced 15 mph limits at every eligible school location by the end of his first term.
The plan covers about 2,300 school locations, which house about 3,200 public, private, parochial and charter schools. The first stage works like this:
- More than 800 locations are added in 2026, bringing the total to about 1,300 by the end of the year.
- About 700 of them are existing 20 mph School Slow Zones that move to 15 mph.
- About 100 are new 15 mph zones at places that were 25 mph.
Each school goes through a 60-day notice and comment period with the local community board first, and sites are prioritized using safety data. The first zone went in on 147th Street between Barclay and Sanford Avenues in Flushing, Queens, near Flushing International High School. The most dangerous locations can also get speed humps and hardened daylighting.
Do NYC speed cameras make streets safer?
Yes, the city's data shows less speeding and fewer injuries where cameras operate. NYC DOT reports that daily violations at camera locations have fallen 94 percent since the program began in 2014.
- Locations with cameras installed in 2022 had 14 percent fewer injuries and fatalities from 2021 to 2023 than control corridors without cameras.
- After overnight and weekend enforcement began, camera locations saw 9 percent fewer injuries than control locations during those hours.
- Overnight and weekend violations fell 40 percent in the two years after August 2022.
- Most vehicles that receive a violation, 74 percent, receive no more than one or two a year.
The need is real. DOT says speeding accounts for about a quarter of the city's traffic fatalities each year, and 209 people lost their lives in speeding-related crashes from 2021 to 2023.
The physics explains why a few miles per hour matter so much. DOT says a driver at 40 mph needs 165 feet to perceive, react and brake, twice the 85 feet needed at 25 mph. A pedestrian struck at 30 mph is twice as likely to be killed as one struck at 25 mph, and the Mayor's Office says a person struck at 25 mph is more than three times as likely to be seriously injured as one struck at 15 mph.
What do NYC's speed rules mean for your next drive?
For your next drive, the simple version is this: treat 25 mph as the top number on city streets, watch for 15 mph school signs that may be new since your last trip, and remember that the time of day no longer matters. If you are driving a familiar route, it is worth looking at the signs again, because the limits on your own block may change this year.
Ghost is a good companion on these streets. It runs next to Google Maps and warns you safely from the background with a banner and a tone over your music, about 700 meters (roughly 0.4 mile) ahead of a known fixed speed camera and again at 250 meters, and as you get closer it shows the exact distance clearly. It works on CarPlay, Android Auto and Apple Watch and covers more than 125,000 speed cameras worldwide. Ghost does not warn about police checks and does not detect radar, so the signs still come first, and you get to keep your eyes on the road and your mind on the people around you.
