what do i need for emissions test

For most emissions tests, you usually need your vehicle, current registration, and sometimes a renewal notice or prior inspection report. In many places, the car must also be in working order with the check engine light off and no obvious safety issues.

Quick scoop

What to bring can vary by state, but a common checklist is:

• Vehicle registration.

• Renewal notice, if you received one.

• Prior inspection report, if your state asks for it.

• A letter or notice from the local emissions agency, if applicable.

Before you go

A lot of places also check whether your car is ready for testing. For OBD- based tests, a lit check engine light or recently cleared computer codes can cause you to fail or be turned away until the car is ready.

One practical tip

If you are not sure what your area requires, check your state or county emissions program before heading out, because requirements and exemptions vary a lot by location and vehicle year.
