Vehicles registered in Lake and Porter counties are required to undergo emissions tests and tampering inspections every two years if they were manufactured after 1976 and have a gross vehicle weight rating (GVWR) of 9,000 pounds or less. Vehicle manufacturers typically print the GVWR on the driver-side door jamb.
Vehicles manufactured in odd-numbered years are tested during odd-numbered years and vehicles manufactured in even-numbered years are tested during even-numbered years. Exemptions include vehicles manufactured during the four latest model years and antique vehicles (as defined by 326 IAC 13-1.1-1 - see Section 1 on page 2). For instance, a vehicle with a manufacturer's model year of 2009 should be tested in 2013, and tested again in 2015 and 2017.
Bring your Indiana Vehicle Registration Renewal notice or your current registration with you to the testing station.
If your vehicle is driven by a college student who is away at school or if the vehicle is kept in another state for part of the year, early testing is recommended. Vehicles can be tested as early as October of the year before they are due. To save yourself some time, take your vehicle in for testing on off-peak days.
