Source: RVV 1990 annex 1 · checked 2026-10-23

Shape and colour

Round grey sign with a black diagonal bar: end of the zone.

Where the sign stands

At the start of the closed section, directly after the junction (about 3 m), on the right and for C1/C2 often repeated on the left.

What the exam asks about this sign

The question is what applies after this sign: the restriction of the low-emission zone lapses and every vehicle may drive again. Trap: candidates think a zone sign must be repeated at every following junction; a zone covers the whole area up to the end sign without repetition.

No practice question uses this sign; the sections below explain it.
