In Maryland, a vehicle emissions test is required for many original registrations, as well as for registration renewals. Renewal notices are sent to vehicle owners (typically eight weeks before the deadline), and indicate whether and by what date an emissions test must be completed.


A car, truck, motor home or RV (recreational vehicle) requires an emissions test when:

  1. It is a 1977 model or newer.
  2. It runs on gasoline


Emission tests are valid for two years. A valid test is required to reinstate a suspended registration and to complete an original vehicle registration or registration renewal. Used car dealers are required to issue a valid emissions test for any vehicle they sell. Getting an emissions test is the buyer's responsibility when the vehicle is purchased from a private owner.


A vehicle is exempt from emissions testing when:

  1. It is a new vehicle, with its date of manufacture within the current two year checkup cycle.
  2. It is a hybrid-electric vehicle with meets the exemption norms.
  3. It is a 1976 model or older.
  4. The vehicle is powered by diesel or electricity.
  5. It is a vehicle driven by a senior citizen (over 70 years) or a physically challenged person and is not driven for more than 5000 miles in a year, and a waiver application has been submitted to the VEIP.


Any of the Authorized VEIP Emissions Inspection Stations licensed by the State can test your vehicle.


The test fee for the VEIP is $14. A late fee of $15 is charged on the day after the due date and for every 28 days from then on.


If your vehicle fails the emissions test, you must have the vehicle repaired, after which it must pass the after repairs emissions test. The station representatives at the testing location will advice you about the next course of action. The vehicle can be repaired at any of the VEIP Certified Emissions Repair Facilities or by any mechanic of your choice. The vehicle must be repaired and prepared for a re-test within a period of 120 days. The first re-test is not chargeable. If your vehicle is unable to meet the emissions standard following the necessary repair work, you may be able to obtain a two year waiver, if you must have made emissions-related repairs to your vehicle totaling at least $450.
