"Twenty-five in certain areas?" Kathy Bruml, a resident from the Upper West Side, said.
"It's 55, unless it's posted otherwise," said Mikel Sacher, a resident from the Upper West Side.
It's actually 30 m.p.h.
That is why the Department of Transportation and NYPD are rolling out a new public awareness campaign to slow drivers down.
According to a new pedestrian study and accident report, pedestrians in Manhattan are killed or injured four times more than in other boroughs.
"The fact is many New Yorkers don't know what the speed limit is. It's 30 miles an hour, and 30 for a reason," Janette Sadik-Khan, New York City DOT Commissioner, said.
That reason explains in a public service announcement airing on TV and the internet.
"We have received a 150-thousand grant from the state for increased enforcement," NYPD Commissioner Ray Kelly said.
We pulled out our radar on Amsterdam and 85th Street, and clocked cars, trucks and cabs going well over 30 miles per hour - one as high as 38.
Nevertheless, many drivers say in their own defense, they rarely see speed limit signs posted.
"I have never seen a speed limit sign posted in Manhattan anyway, I've never seen a sign," said Mark Ossenheimer, a resident in Upper East Side.
The city has installed 1,500 new crosswalk signals and cyclists will also be ticketed if they don't obey the laws.
