Local border traffic

Local border traffic or small border traffic is cross-border traffic of residents of a border area. In many cases local border traffic is subject to bilateral regulation aimed at the simplification of border crossing for these residents.
Often, additional border crossing points are created to carry only local border traffic.
The European Union rules on local border traffic were established by Regulation (EC) No 1931/2006 of the European Parliament and of the Council of 20 December 2006.
