How to Test Exhaust Emission
Exhaust emissions contribute to a large amount of the pollution that now exists in the atmosphere. To reduce the emissions that are released by cars, state laws require that many vehicles be tested in order to determine whether the car meets emission standards.

Visit your states inspection center. A routine part of each inspection is to test your vehicles emissions. The inspection sticker on your mirror will let you know when you are due to have your exhaust emissions and car inspected.
2Wait for your car to be placed on the machine used by the inspection station for the test. An on-board diagnostic test and idle test are the tests used to inspect emission systems. The system is going to check how well your emissions system works and if its up to state standards.
3Find out if your exhaust emissions have passed the test. The inspection station is going to let you know immediately whether your car meets the standards or not.
4Take your car in for repairs if you fail. If your car fails the test, you need to go to an emissions repairman to fix the problem. Once the repair has been done, you can return to the inspection station to test the exhaust emissions again.
