Fraudulent emissions systems
DVSA’s enforcement staff, and their European counterparts have found evidence that drivers and operators use emissions cheat devices to cut the cost of operating. These include:
- using devices designed to stop emissions control systems from working
- removing the diesel particulate filter or trap
- using cheap, fake emission reduction devices or diesel exhaust fluid
- using illegal engine modifications which result in excessive emissions
- removing or bypassing the exhaust gas recirculation valve
DVSA will be targeting lorry drivers and operators who try to cheat vehicle emissions. The new checks will target those who break the law and will help to improve air quality.
Taking action against emission cheats
DVSA enforcement officers will give the driver and operator 10 days to fix the emissions system if they find it’s been tampered with.
If the emissions system isn’t fixed within 10 days, DVSA will issue a fine and stop the vehicle being used on the road.
DVSA enforcement staff can insist that a vehicle is taken off the road immediately if they find a driver or operator is repeatedly offending.
