Speed decides how much time you have to react and how far you travel before you stop. A limit is a ceiling, not a target: rain, fog, schools and traffic make the safe speed lower.
Some highways also set minimum speeds, and driving far below the flow can be as dangerous as speeding. NY Driver’s Manual
The idea behind it
Roadfeel’s road-sense principles
Speed eats up your reaction time Every extra mph covers more ground before you even touch the brake, and braking distance grows much faster than speed. Speed rules buy you time.
All the rules, in our words
Tags show the kind of rule and whether it’s a written-test point or matters on the drive test (our tagging). Each rule links to its official source.
Where no speed limit is posted, the maximum anywhere in New York State is 55 mph.
California differs: California’s default is 65 mph on most highways (55 on two-lane undivided roads); New York’s unposted maximum is 55 mph, and 25 mph in New York City. California rule
New York City’s speed limit is 25 mph unless a sign says otherwise, and other cities may have lower limits that aren’t always posted.
California differs: California’s 25 mph default covers business and residential districts; in New York City it is the default on every street without a posted limit, including big avenues. California rule
The limit is a ceiling, not a target. On a slippery or foggy expressway posted 55 or even 65 mph, you can be ticketed at 50 mph for going faster than is reasonable for the conditions.

Show answer

Wei is driving along a wide, six-lane avenue in Brooklyn. Traffic is light, and no speed limit sign is posted on the avenue. What is her speed limit?
25 mph, the city’s limit on every street without a posted sign
30 mph, because 25 mph applies only on residential streets
35 mph, because a wide avenue counts as a main highway
55 mph, the statewide limit wherever no sign is posted
Show answer
Answer: A. 25 mph, the city’s limit on every street without a posted sign
In New York City, 25 mph is the limit on every street with no posted sign, big avenues included. It isn’t just for residential or business blocks. The statewide 55 mph is only a ceiling, and the city’s own default is lower.
Which of these drivers is most likely to get a ticket for driving at an unsafe speed?
Carlos, going 55 mph on a dry, clear road posted at 55
Lin, going 50 mph in thick fog on a road posted at 65
Priya, going 60 mph on a dry, clear road posted at 65
Dmitri, going 25 mph on a clear, unposted street in Queens
Show answer
Answer: B. Lin, going 50 mph in thick fog on a road posted at 65
Your speed has to suit the conditions, not just the sign. In thick fog, even 50 mph on a 65 mph road can be too fast, and you can be ticketed for it. The others are at or under the limit in good conditions.
