Exhaust Emissions Testing Requirements

 

Every domestic vehicle will soon be required by law to pass a Department of Transport test (DOT) that has been carried out at a government-certified testing station. the purpose of this test is not to ensure that your vehicle meets the minimum standards that the law dictates on the day of the test, but also to ensure the safety of other road users and the environment. An essential part of the DOT test is now vehicle exhaust emission testing. This is carried out to ensure that the exhaust gases emitted by any vehicle are within the permitted levels stipulated by both national and international laws.

During the DOT each vehicle has to meet the minimum standards for exhaust emission, though this varies depending on the age and type of fuel that the vehicle uses. The examiner connects the vehicle to a computer during the DOT test and takes readings and measurements from the exhaust gases that are emitted. if any of those levels are exceeded, then the vehicle will fail its DOT test and will need to be re-tested after the necessary repairs have been undertaken.
