The level of toxic emissions pumping from the exhausts of diesel cars is still not being fully tested in Northern Ireland regardless of the law.
It was revealed in 2018 that tests on the potentially harmful fumes had not been carried out since 2006 in a Spotlight special.
Despite the outrage that followed, we can reveal diesel cars still aren’t being fully tested for emissions that could add to the air pollution that kills around 500 people in Northern Ireland every year.
