A box junction is a traffic control measure designed to prevent gridlock at busy road junctions. The surface of the junction is marked with a criss-cross grid of diagonal painted lines (or only two lines crossing each other in the box junction) and vehicles may not enter the area so marked unless their exit from the junction is clear (or, if turning, to await a gap in the oncoming traffic flow). In the United Kingdom, drivers may enter the box and wait when they want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right.

Alternatives to the box junction

In many U.S. states, laws intending to decrease gridlocking at intersections, rail crossings, and marked crosswalks have been enacted which prohibit motorists from entering any of the three until they are certain their vehicle can clear it. ^[1] No special road markings are used to indicate this rule, but some governments post "DO NOT BLOCK INTERSECTION" signs to increase awareness of the law at problematic intersections.
