Single File Traffic Supplementary Plate 518

This “Single file traffic” sign should only be used with triangular warning signs 516, 517, or 520. Used to inform drivers that the road narrows to the point where only one vehicle may fit in either direction.

The sign can be customised by choosing an X-height for the text that suits the road the sign is to be deployed on. It can also have an arrow, a distance such as “100 yds” or a combination of both . To purchase a variant of this supplementary sign above with arrows or distance markers please call 01905 794 875.

For full guidance on how this sign should be used please consult the official TSRGD guidelines which we have linked to on our regulations page.
