Failures & Retests
The state of Indiana requires emissions testing in an effort to reduce the emissions of pollutants from vehicles and to provide a cleaner air quality in Indiana.
There are some testing tips for your vehicle that the state of Indiana recommends. if your vehicle was manufactured between 1976 and 1995 it is recommended that you fully warm up your vehicle before having the emissions tested. You should make sure that your brakes are in good condition because poor brakes can result in testing difficulty which can cause your vehicle to fail the Indiana emissions test. Finally, you should ensure that your front wheel drive vehicle has proper alignment. Alignment that is poor can also result in the vehicle failing the emissions testing.
If your vehicle from 1996 or later if you have a ‘check engine’ light displayed it is recommended you get that fixed before bringing your vehicle in for emissions testing.
In Indiana, only vehicles belonging to residents of Lake and Porter counties need to be tested for emissions.
