School zone

A school zone refers to the area of a street near a school, where the speed limit is reduced to protect student pedestrians.

In many U.S. states, elementary schools, middle schools (or junior high schools), and high schools often have different speed limits, which are set lower for the younger children. Fines for speeding are also often increased, or in some states the "grace" (usually anything less than 10 MPH, or up to 15km/h) normally allowed over the posted limit is eliminated.

A school zone is only applicable during posted weekday hours when school is in session, usually for about one hour before school begins and after it ends. Most cities have this indicated by flashing amber lights set on a 7-day timer, however some rural areas expect drivers to read the hours on a sign. If the police use the signs to stop someone even when school is not in session, this is considered a ticket trap.
