In Service Exhaust Emission Standards for Road Vehicles

This booklet explains the test procedures used to check vehicle exhaust emissions which Testers and Vehicle Examiners will follow whether at the roadside or during the Ministry of Transport (MOT) test. It contains, in the Annex, emissions limits for vehicles fitted with advanced emissions control systems such as three way catalytic converters, and offers general advice to motorists and vehicle operators on submitting vehicles for test. The booklet deals separately with petrol-engined vehicles and those with diesel engines. The limit values contained in the Annex to this booklet form part of the Road Vehicles (Construction & Use) Regulations 1986 (as amended) and these will be used for the in-use emissions testing of vehicles fitted with advanced emissions control systems. The information contained in Tables 1 & 2 detail the legal requirements for vehicles not fitted with these advanced systems and for the few model types not included in the Annex. For diesel vehicles, the requirements are outlined in Table 3. The test procedures described in this booklet are included solely as a guide; they do not form part of the Regulations. Detailed test procedures are described in the: MOT Inspection Manual, Private Passenger and Light Commercial Vehicle Testing; and HGV Inspection Manual and PSV Inspection Manual.
