no speed limit sign posted on my street, would i be speeding?
 

i live in southern, NJ and on my street (mannheim ave) starting from the main intersection at white horse pike (rt 30) all the way to where mannheim ave dead ends into the woods around 5 miles down there is no speed limit sign posted. in my 15+ years of living there there never has been one posted as long as i can remember. i usually go around 60mph driving daily to and from home here, and once in a while, do a quarter mile timing. (the entire street is level and straight so visibility is easily 2+ miles)

my question is, would there be a "default" speed limit for my street even tho there is no speed limit sign?
(the 4 or so streets that intersect mannheim have speed limits posted at 45, with rt 30 at 55mph)

also, even though there is no speed limit sign could i still be pulled over for speeding?

note. i've never been pulled over. ever.

check your vehicle code for nj, I know in pa for a non posted speed limit, there is a default speed depending on the type of area it is.
