School zone

during certain hours.

Fines

Fines for speeding in school zones may be enhanced. For example, many states double speeding fines in school zones.

When effective

School zone speed limits are often, but not always, only applicable during posted weekday hours near the beginning and ending of school when children are likely to cross roads. In some places, the school zone speed limit is effective at all times when school is in session, plus additional time before and after the school day. Flashing amber lights often indicate when the school zone is effective. When a school zone also has a large playground facility, it may double as a playground zone and the speed limit could be in effect longer - or at all times of day, every day.

In California, school zones are in effect only if children are present, and usually have a speed limit of 25 MPH, or 40 km/h.

School zones may also sometimes be in effect during school holidays, due to holiday programmes that use school premises. In some locations however, school zone signs will be locked up during school holidays so that motorists can drive to the normal speed limit.

School zones typically have speed limits between 15 and 25 mph (25 and 40 km/h).

Overtaking (or passing) vehicles in active school zones is prohibited in some cities.

Effectiveness of zones

There are suggestions that school zones may not be effective in reducing traffic speeds or in reducing road casualties. In a review of the available research, the Committee for Guidance on Setting and Enforcing Speed Limits of the Transportation Research Board, part of the United States National Research Council, stated: [cite book
