交通上の市街地境界は自治体の行政境界と必ずしも一致しません。法的意味はその国の道路標識と交通規則によります。
What is a city limit?
A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.
Does a city-limit sign always mark a built-up area?
No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.
Does passing a city-limit sign always change the speed limit?
No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.
Is a city limit the same as a municipal boundary?
Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.
What is the difference between a city limit and a built-up area?
A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.
