I saw two 21 mph speed limit signs in Morristown, NJ on some side streets of James Street. I think the side streets were on Sherwood Drive and Nottingham Court. If those were them, then they were the block before or after. Saw them in spring 2012.
Yes. A speed limit sign is an example of a regulatory sign.
In the UK the speed limit comes into force as soon as you pass the speed limit sign. As such the distance is zero as you should have slowed down to the posted speed limit before passing the sign.
When it is flashing the speed posted is the limit
A motorist is expected not to drive faster than the speed limit on the sign until the school has been passed.
It is unknown who invented the speed limit sign. However, the first maximum speed limit was the 10mph (16km/h) limit introduced in theUnited Kingdomin 1861.
It varies by jurisdiction.
Prospect Street, Cambridge, MA. It's off of Mass Ave.
When another speed limit sign is reached that changes the limit from the previously posted one.
Regulation Sign Example will be the Speed Limit 50
The increased speed limit goes into effect AT the speed limit sign, not at any point before that. While you're not likely to get cited for accelerating at a reasonable point before you actually get to the sign, you're still bound by the prior speed limit until you actually reach that sign.
ur dumbos of course not
the speed limit is enforced when it is in sight of a person
