Speed limits — New York Permit Test
Speed limits on the New York permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver must obey the speed limit, and where no limit is posted they must drive no more than 55 mph.
A road with no sign still has a ceiling. It is the number to fall back on.
If no limit is posted, drive no more than 55 mph (88 km/h).
It is often common sense to keep actual speed below the posted limit, because a police officer could ticket a driver for a speed that is not reasonable for the conditions.
The posted number was set for a dry, clear day. Fog and ice are not that day.
Often, it is common sense to keep your actual speed below the posted limit.
Some highways have minimum speed limits to keep a smooth traffic flow, and a driver slower than the minimum speed can interfere with the flow and create a dangerous condition.
Traffic that has to swerve around a slow car is traffic doing something risky.
To keep a smooth traffic flow, some highways also have minimum speed limits.
Some cities have speed limits less than 55 mph that are not always posted, and the speed limit is 25 mph in New York City unless another limit is posted.
The city sets its own floor and does not sign every block. A driver has to bring the number.
For example, the speed limit is 25 mph (48 km/h) in New York City unless another limit is posted.
Even where there is no minimum speed limit, those driving too slow can be as dangerous as those who drive too fast.
A slow car in fast traffic is an obstacle. Everybody else has to work around it.
Even if there is no minimum speed limit, those driving too slow can be as dangerous as those who drive too fast.
On the test
How fast may a driver go where no speed limit is posted?
55 mph. A road with no sign still has a ceiling. It is the number to fall back on. New York State Driver's Manual, p.47: “If no limit is posted, drive no more than 55 mph (88 km/h).”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
