D18 Mandatory Sign – Compulsory Direction for Dangerous Goods, Right, 50x65 cm, Class I

D18 Mandatory Sign – Compulsory Direction for Dangerous Goods, Right, 50x65 cm, Class I

The D18 sends vehicles carrying dangerous goods along their route: the white panel shows a lorry with the dangerous goods plate and, below it, a blue disc with a white arrow curving to the right.

When class I is used

The sign has class I (RA1) retroreflective sheeting: 70 cd/(lx·m²) for white and a 7-year service life. It is the economical choice for places without many light sources, such as local, minor and private roads or streets without strong lighting. Where there is street lighting, shop windows or advertising, SR 1848-2 requires prismatic class 2 or 3 sheeting, which stands out better against a lit background.

Where it goes, under SR 1848-1:2024

It goes no more than 15 m before the entrance to the junction where vehicles carrying dangerous goods must follow the route shown.

For all mandatory signs, SR 1848-1:2024 provides that their meaning applies in the immediate vicinity of the place where they are installed, before or after it.
