Vehicle Inspection vs. Emissions Testing

A VIN inspection is not the same as an emissions test.

Some out-of-state vehicles need a VIN inspection as part of the Indiana titling process. This verifies the vehicle’s identification information; it does not test exhaust emissions.

Before You Go

If you’re registering a vehicle in Allen County:

Make sure your BMV address is current.
Have your title and registration documents ready.
Bring proof of insurance when required.
Check whether a VIN inspection is needed.
Don’t schedule an emissions test simply because you’re registering in Allen County.

Local Tip

If an online search tells you that “Indiana requires emissions testing,” don’t assume that applies statewide. Indiana’s program is geographically limited.

Allen County vehicles are not subject to the Lake and Porter County emissions testing requirement.
