From the DMV handbook...
"Around Children

When driving within 500 to 1,000 feet of a school while children are outside or crossing the street, the speed limit is 25 mph unless otherwise posted. Also, if the school grounds have no fence and children are outside, never drive faster than 25 mph. Some school zones may have speed limits as low as 15 mph. Always drive more carefully near schools, playgrounds, parks, and residential areas because children may suddenly dart into the street. Also, many children have not yet developed the ability to judge speeds and distances well enough to cross streets safely when cars are moving fast."
