Legislation UK | Vehicle Configuration
The law governing vehicle spray suppression systems in the UK is outlined in the Road Vehicle (Construction and Use) Regulations.
This law requires certain categories of vehicle and trailers (see below) to be fitted with Spray Suppression Systems that meet either the requirements of the British Standard BS AU 200 or the requirements of the European Directive 91/226/EEC. Compliance with either is deemed satisfactory in the UK.
The Spraydown mudflap is certified both as a Suppression Device under BS AU 200 and has been type approved by the VCA as an Air Water Separator Device under the European Directive 91/226/EEC.
The following vehicles and trailers are subject to the Spray Suppression Regulations:
| UK | EU | |
| Vehicles | Motor vehicles exceeding 12 tonne GVW first used on or after 1 April 1986 | Vehicles over 7.5 tonnes after 10 April 1992 |
