Washington Ended Emissions Checks: Does That Save Your Old Car?

Blog · By Free Junk Car Hauling · Updated · 4 min read

Maybe you put off a repair years ago because you were sure the car would never pass an emission check. Or maybe you have a dashboard light that you thought would doom the car, and you just found out the checks are gone. Does that mean your old car is good for another few years?

It might be. If a failed emission check was your only reason to junk the car, that reason has gone away. But the end of one program does not change whether the engine is healthy, whether the car is safe, or what other state rules apply.

Short answer

Yes, Washington’s emission check program ended on Jan. 1, 2020, so passing that check is no longer a reason to junk a car. But tampering and excess smoke rules remain, and tabs still expire every year. If your only worry was the old test, keep the car if it is otherwise safe and sound. If it has failing or unsafe systems, judge it on those instead.

So the old check is gone, but the car still has to be legal in other ways. If you have a question about your own vehicle, ask the Department of Licensing.

What this changes for your decision

Here is how the end of the checks affects some common situations.

Your situationWhat it means now
You were going to junk the car only because it failed the old checkThat reason is gone. Judge the car on how it runs and whether it is safe.
A check engine light is onThe light still means something. Have it scanned, since it may be minor or a sign of real trouble.
The car smokes heavilyExcess smoke rules remain, and smoke often means a mechanical problem. See burning oil.
It has a failing catalytic converterThe check may be gone, but tampering rules remain. Ask a shop for a legal repair.
The engine or transmission is failingThe end of the checks does not change anything here. Use our repair or junk guide.

The check engine light still matters

With no emission check to pass, it is tempting to put tape over the light and forget about it. Please don’t. The light is how the car tells you something is off. Sometimes that is small, like a loose gas cap or a tired sensor. Sometimes it is a misfire that could damage a catalytic converter, or a fault that later leaves you stranded. A flashing light usually means something more urgent, so ask a mechanic before you drive it further.

Questions to ask your mechanic

  • What codes does the car show, and what do they mean in plain language?
  • Does this affect safety, or could it damage anything else if I wait?
  • Can this wait, and what symptoms should I watch for?
  • What is the smallest repair that actually solves it?
  • Would any part of this repair remove or disable emissions equipment? If so, is there a proper repair instead?

When keeping the car is the better call

Keep it, and fix what is needed, when:

  • The old check was your only reason to get rid of it.
  • It starts reliably, and a mechanic has checked it over and says it is safe.
  • Any warning light has been looked at and found to be minor or fixable.
  • Your insurance, tabs and parking still make sense for what you get from the car.

Before you decide, it may be worth getting a basic inspection on a car that has been sitting. Our guide on a car that has sat for years explains what to look for.

When it still is not worth saving

The end of the checks helps with one thing only. These still stand as reasons to let a car go:
