How Often Do You Need a Car Emissions Test in Baltimore, MD?

There are several different emissions tests, each of which is designed to test the level of dangerous chemicals emitted by your engine. If your car is found to emit more chemicals than it should, your car will need to be examined by technicians to correct the problem. Emissions tests are due every two years, and these tests coincide with your registration renewal. New cars and hybrid cars are not required to have an emissions test until the third year after their first registration. Certain other categories of cars are not subject to emissions testing due to age. Electric cars also do not undergo emissions testing as they produce no emissions regardless of age.

What Do You Need for the Test?

You need to book a test at one of the emissions testing centers in Maryland. These testing centers are certified by the Maryland Motor Vehicle Administration (MMVA). You’ll need to take your driver’s license, emission test notification letter, proof of insurance, and payment for the test. If you don’t yet have your emissions test letter, you can take your registration renewal letter instead.

Types of Test

There are several different tests, as mentioned above, but your car will only need to take one of them. These are the different tests and their requirements.

Onboard Diagnostic Test

This test applies to all vehicles from 1996 onwards that weigh up to 8,500 pounds. In this test, your car’s computer is connected to the testing center’s diagnostic system. This system interrogates your computer and then produces a printout of the level of emissions if any.

Gas Cap Test

This test is performed on vehicles manufactured between 1977 and 1985. It tests the gas cap to ensure that it fits securely, has effective seals, and can’t leak gases from the fuel tank.

Tailpipe Test

This test also applies to vehicles made between 1977 and 1985, and it tests the level of emissions that exit the tailpipe when your engine is running.

After the Test

If you’ve passed the test, you’ll be issued a Vehicle Emissions Inspection Program (VEIP) certificate. This certificate needs to be submitted with your registration renewal documents. The testing center will also upload a copy of the results to the MMVA.
