Does my car need a smog check ?

A smog check is a type of test done on the exhaust system of any motor vehicle. This kind of test determines the number of pollutants and the types of pollutants a particular vehicle is emitting. Smog checks involve several assessments of different motor parts related to emissions control, making sure that each part is working effectively. Most countries have smog check requirements to address air pollution issues.

In the United States, some states require a bi-annual smog check, while others require motorists to complete one every year. When your vehicle is less than five years old or more than thirty years old, it can be exempted from such tests. However, most states require a passing smog check when selling vehicles before the title can be transferred to the buyer. Smog requirements vary from one location to the next, so make sure to check with your local department of motor vehicles about these requirements.

Be aware that all vehicles should not exceed emission limits set by your state or city. A smog check is done by connecting a device to the tailpipe with the engine runs to determine the emissions in idle and while revved. These two information can measure emission and compare the state standard for your type of vehicle. Smog technicians will also check if the muffler is in good working condition, if pipes and hoses are connected properly and if the internal computer is in working order.

Your vehicle will fail a smog check if the emissions load exceeds the standard limit, if the exhaust system or muffler is not maintained and if a check engine is present. If this happens, you need to get your vehicle repaired and undergo another smog check.

A smog check is important for any vehicle because not only is it a legal requirement, it also checks if your car working properly. Be aware that personal vehicles contribute up to 40% of pollution, you should be a responsible driver and aid the national efforts to reduce pollution.
