Supplementary Signs

Supplementary Signs

Supplementary signs are used to add specifics or further details to other signs such as regulatory and warning signs. This is a very important step to ensure that roads and car parks operate safely, for example by telling drivers how far it is to speed bumps or a pedestrian crossing. On-the-road supplementary signs can be used to reinforce the message provided by a sign, such as “give way to oncoming traffic”. Shop our collection now, with next-day delivery on in-stock items!

    About Supplementary Signs

    Supplementary signs sit below the main sign face to offer additional information, instructions, or warnings to road users. They might alert drivers to speed bumps or an adverse camber, or tell pedestrians that there’s no footway for 50 yards.

    Some of our signs come with pre-printed messages, and are available in various sizes. These are kept in stock, ready for next-day delivery. For distance-related messaging, you can buy a sign with a blank space for you to add the distance.

    We also make some supplementary signs to order. For example, you can choose the X-height (height of the text in mm) to suit the road where you want to install the sign. All our supplementary signs have R2 (RA2) reflectivity.
