Failing a smog check can be frustrating, especially when you are trying to meet a DMV registration deadline. The good news is that a failed smog check does not mean the end of the road. Understanding what happens next can help you stay calm and move forward quickly.

Why Vehicles Fail Smog Checks

Vehicles can fail a smog check for several reasons. Common issues include:

  • Emissions readings outside acceptable limits
  • A check engine light that is on
  • Problems with emissions related components

In some cases, a vehicle may fail due to something simple, such as a loose gas cap or the engine not being fully warmed up. Other times, repairs may be required before a retest.

What Happens After a Failed Smog Check

If your vehicle does not pass, the smog station will provide test results explaining why it failed. These results are important because they guide the next steps.

A failed test is not sent to the DMV as a pass. Instead, you are given the opportunity to make the necessary repairs and return for a retest. There is no penalty for failing, but registration cannot be completed until the vehicle passes.

Tips Before Returning for a Retest

Before coming back for a retest, it is important to address the issues listed on the failed report. Helpful tips include:

  • Complete all required repairs
  • Drive the vehicle after repairs so systems reset properly
  • Make sure the check engine light is off
  • Confirm the vehicle is running normally

These steps improve the chances of passing and help avoid repeat failures.
