Humps for X miles' Supplementary Plate - Post Mount Dia. 557.2 R2/RA2
This supplementary plate is installed alongside sign face 557.1 to indicate the distance that the speed bumps are along the following route. The sign face reads “Humps for” then a unit of measure for the distance.
The distance value on this sign can be customised to suit the installation location. For private road use, we have a "speed bumps ahead" sign which is kept in stock with a fast delivery time.
