Anyone who owns a car should know that a smog check should be done regularly to ensure that the car is functioning properly and that the emissions do not exceed the maximum rate. In fact, this check is so important, that by law, it is a requirement for car owners.
This is beneficial to both the car and the environment because the test checks if the car needs repair and to make sure damage done to the air quality is minimal. Getting a regular smog check if you don’t own a hybrid, electric, or natural gas powered car* is one way to be responsible in managing one’s carbon footprint while avoiding any accidents that come with defective cars.
A smog test is done by a technician who attaches a device to the tail pipe while the car is on neutral gear and when revved up. A measurement is captured by the device which indicates if the car is emitting less than the required maximum. When a car fails a smog check, repairs should be made accordingly until the emissions reach a reasonable rate.
Other tests are done during the smog check. The technician will even make sure that all connections (pipes, computer, muffler, et al) are secure for the car and in order.
Different states have varied requirements when it comes to smog check requirements. Usually annual or biannual checks are done. It is best to find out when exactly to have the smog test done in your state Department of Motor Vehicles.
Although it may be a big hassle to car owners, it is an easy trade off when you have the convenience of owning a car.
