‘Smog testing’ sounds kind of heavy, but you’ve already heard of it before – Just as ‘emission testing’. It simply consists of measuring the amount of pollutants that are coming from your exhaust system in order to determine that they are being handled efficiently by your emissions system.
This isn’t just about pollution, however, as poor emission handling means that you aren’t getting the kind of mileage that your vehicle is designed for. That’s because your emissions system is designed not only for cleaning those emissions, but for also trapping gas vapors and rerouting them to your engine to be burned as fuel.
Basically, it ensures that you won’t waste gas and that the gas is being converted to energy as cleanly as possible. Beyond function, smog testing is important because each state has their own emissions guidelines, and if these aren’t followed then you could be fined or even told that it must be fixed in order to operate your vehicle.
Thankfully, an emissions check is easy to get done and if you’ve been taking care of your vehicle, the odds are that you’re going to pass with flying colors.

While you will want to double check the law in your particular state, in most states that require emission testing there is an exemption for vehicles which are over 24 years old. With that said, be sure to double check it – Laws change all the time and you wouldn’t want to get an expensive ticket for a routine check that you should be doing anyway.
No, California is not getting rid of smog checks anytime soon, and are looking to phase-out gasoline powered vehicles by as early as 2035. Currently they are expanding their emission testing requirements for trucks and other large vehicles and if you own a car then it’s safe to say that you’re definitely going to need a smog test if you live in California.
Most states are going to require that you get a smog check, although there are some exceptions. In Alabama, Alaska, and Arkansas a smog check is not required and this is also the case in Florida, Hawaii, Iowa, Kansas, and Kentucky. Finally, you don’t have to take a smog/emissions test in Michigan or Minnesota, either, although emissions testing is still a good idea.
Aside from the health considerations, when your emissions are excessive, you aren’t getting the mileage that you could be if your emissions system was running in tip-top shape!
