3 questions from the New York practice test
1. When no speed limit is posted in New York, what is the statutory maximum speed?
- 45 mph
- 55 mph
- 35 mph
- 65 mph
Show answer
55 mph. New York's general statutory maximum is 55 miles per hour where no other speed limit is posted. That number is a ceiling, not a guarantee that 55 is safe for rain, congestion, darkness, or a work area. The 45, 65, and 35 mph choices belong to other road classifications or special postings. First check for a sign; if none applies, use 55 as the legal default and still adjust for conditions.
2. Unless a different sign is posted, what is the speed limit in New York City?
- 30 mph
- 55 mph
- 35 mph
- 25 mph
Show answer
25 mph. New York City has a 25 mph speed limit unless another limit is posted. The statewide 55 mph default does not override this city rule, and 30 or 35 mph may apply only where a different sign establishes it. Look for the posted limit on the specific street and then account for pedestrians, traffic, and visibility. The short exam cue is city streets default to 25, subject to signs.
3. On a slippery or fogged-in expressway, how should the driver's actual speed compare with the posted limit?
- It should be much lower than the posted limit when conditions make that necessary
- It should always equal the posted limit
- It may exceed the posted limit if traffic is moving quickly
- It should stay at the limit until visibility becomes zero
Show answer
It should be much lower than the posted limit when conditions make that necessary. A posted limit sets a legal maximum, but it may still be unsafe in slippery or fogged-in conditions. The manual gives an expressway example where the legal limit can be 55 or 65 mph while the safe speed is much lower. The choice that keeps speed at the limit ignores the hazard, and exceeding the limit is never justified by fast traffic. Watch the pavement and sight distance, ease off early, and choose a pace that leaves room to react.
