What is the speed limit in a residential or business district in New Jersey?
Unless a sign says otherwise, what is the default New Jersey speed limit in a typical residential or business district?
The answer
25 mph, unless otherwise posted. Certain low-density business and residential districts have a 35 mph limit.
New Jersey's state driving FAQ says the limit, unless otherwise posted, is 25 mph in school zones and in business or residential districts. It lists 35 mph in certain low-density business and residential districts and 50 mph on all other roadways.
Posted signs control, so always follow the number on the sign over the default.
Exceptions
- A posted limit overrides the default.
- The page says 35 mph applies only in certain low-density districts.
Why this rule matters for safety
Residential streets have driveways, parked cars and pedestrians, so a lower speed gives more time to react.
