This article details the UK's Road Vehicles (Construction and Use) Regulations 1986, requiring most vehicles over 12t and trailers over 3.5t gross weight to be fitted with approved anti-spray equipment, although six types of vehicles are exempt. All spray-suppression equipment must comply with British Standard BSAU200, which specifies two requirements for valances, whose functions include separating air and water and improving air flow through the wheel, to reduce spray. Comprehensive specifications are given for fitting valances, and for wheel flaps used with valances. Specifications are also given for procedures to be followed when conventional mudguarding equipment is used, and when there is multi-mudguarding over tandem axles or bogies. All anti-spray devices and their parts must be maintained free from any obvious defect likely to prevent them from working properly. Fitting dimensions must be maintained, especially when flaps are damaged. All dimensions must be measured when the vehicle is unladen and the load platforms of semi-trailers are level. Anti-spray equipment is examined during the vehicle's annual test, and is described at Item 14 in the Inspection Manual. The article also outlines the penalties that can be imposed for failing to obey the regulations.
