207. Box junction
A box junction is a marked area of the roadway, usually located at an intersection, that must be kept clear to prevent vehicles from blocking crossing traffic. It is commonly indicated by a box filled with diagonal or criss-cross road markings, although its appearance and legal meaning can differ between countries.
Drivers should generally not enter a box junction unless there is enough space to leave it. This helps keep intersections clear when traffic is congested and prevents vehicles from obstructing traffic travelling in other directions.
