ゾーン日本

A traffic zone is a defined area in which a particular restriction, prohibition or obligation applies throughout the included roads rather than only at one location.

A traffic zone normally begins with a zone-entry sign showing the applicable rule. A corresponding end-of-zone sign indicates where that rule stops applying.

An ordinary sign usually applies to a particular road, direction, lane or section. A zone sign applies throughout a designated area, which may contain several roads and intersections.

Usually, yes. A zonal rule commonly continues through intersections until an end-of-zone sign is reached. The exact effect of intersections depends on local law.

A traffic zone normally ends when you pass the corresponding end-of-zone sign. The normal road rules or another signed regulation then apply.

Yes. A zone may contain several regulations, such as a speed limit together with parking or access restrictions. Drivers must observe every applicable sign.

Yes. A local sign may introduce a different or more restrictive rule on a particular road or section. Whether the original zonal rule resumes afterwards depends on local law and the type of regulation.

Common examples include speed zones, parking zones, low-emission zones, pedestrian zones, cycling zones, school zones and zones restricting particular vehicle categories.

No. A built-up area is a broader legally defined urban area. A traffic zone imposes a specific signed rule and may be located inside or outside a built-up area.

No. A residential area describes an area mainly used for housing. It may contain one or more traffic zones, but the terms do not automatically have the same legal meaning.

Not necessarily. The sign, symbol or additional panel may limit the rule to particular vehicles, road users, times or circumstances.

Observe the entrance sign carefully, identify every displayed rule and remember that the regulation may continue across several roads and intersections until the zone ends.
