From August 2017, roadside checks of lorries carried out by the Driver and Vehicle Standards Agency (DVSA) will include an emissions check.
DVSA will be target 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.
Products such as the DVSA-approved SmokeCheck offer a convenient way for operators to check themselves that their vehicles comply with emissions regulations.
