School zone

The most common offences that occur in a school zone also attract demerit points.

[citation needed] In California, school zones are generally in effect only "when children are outside or crossing the street",[1] and usually have a speed limit of 25 mph, or 40 km/h.

School zone signs are sometimes amended with the notice "When children are present" (as shown on the photo), which emphasizes its definition in the drivers' handbook.

Overtaking moving or stationary vehicles in active school zones is prohibited in some jurisdictions.

[2]In the Canadian Journal of Civil Engineering it was concluded that "the results of this study provide strong evidence that reducing speed limits to 30 km/h in school zones can bring significant safety benefits by reducing vehicular speeds and fatal and injury crashes.
