What Happens If Your Vehicle Fails the Test

If your vehicle fails, the testing station will provide a detailed report showing which emissions standards it did not meet. Common failure reasons include a faulty oxygen sensor, a malfunctioning catalytic converter, or an engine control problem. The report will tell you what needs attention.

You have 30 days from the test date to make repairs and return for a retest. Most stations do not charge for the retest if you return within this window. You will need to bring proof that repairs were made — usually a receipt from a mechanic — though some stations will retest without documentation if the repairs are obvious.

If you cannot afford repairs when ready, you may be able to obtain a waiver from IDEM that allows you to register your vehicle for one year while you save for repairs. Waivers are not automatic; you must request one from the testing station or contact IDEM directly. may be able to access and the process vary, so ask the station what documentation they need.

Cost and What to Bring

Testing fees in Indiana range from $15 to $25, depending on the station. Most accept cash, debit, and credit cards. Some stations may charge slightly more for certain vehicle types or if additional diagnostics are needed.

Bring your vehicle registration and a valid photo ID. If your vehicle has a check engine light on, the station may still test it, but the light itself can cause a failure. If the light is on, have it scanned for trouble codes before testing — many repair shops will do this for free or a small fee.

If you are retesting after a failure, bring your original test report and any receipts or documentation of repairs. The station will use this to verify that work was done before running the retest.
