Tegelijk groen (Dutch pronunciation: [təɣəˌlɛik ˈxrun]; lit.
'simultaneously green'), commonly translated as all directions green and also known as a bike scramble,[1] is a traffic rule in the Netherlands allowing bicycles to cross designated intersections at the same time from all sides.
On the Groningen crossings where tegelijk groen was introduced, no more fatal accidents between bicycles and motorised traffic have occurred since.
Cyclists must coordinate the crossing spontaneously, as no side has priority.
[2][3] The rule will be introduced on intersections in Belgium under the name square green for cyclists (Dutch: vierkant groen; French: vert intégral) on 1 September 2026.
