Safety Inspections for Used Vehicles

Most used vehicles and new resident vehicles must undergo safety inspections before initial titling and registration. These vehicles include:

  • Cars.
  • Trucks.
  • Motorcycles.
  • Tractors.
  • Trailers.
  • Special equipment.
  • Class B “for hire" vehicles.

Vehicles must be inspected at licensed Maryland safety inspection locations, which include most auto dealers, service stations, and specialized service centers.

When applicable, the inspection location will require:

  • Proof of the vehicle's value.
  • A lease agreement and proof of your monthly lease payments.
  • Any lien information, including lien release documents.
  • Power of attorney documentation.

Generally, safety inspections involve testing the vehicle's basic safety components, such as the:

  • Steering wheel.
  • Brakes.
  • Wheels, tires, and rims.
  • Mirrors.
  • Glass.
  • Horn.
  • Lights and signals.

Safety inspection certificates are valid for 90 days, meaning you must title and register your vehicle before that time period is up.

NOTE: If your vehicle fails the safety inspection, you must have it repaired and retested.

What if You Fail the Emissions Inspection?

If your vehicle fails its Maryland emissions tests, you must have it repaired and retested. Maryland provides a list of VEIP Certified Emissions Repair Facilities (CERFs), but you may choose your own mechanic or do the repairs yourself. If your vehicle is still under warranty, a dealership might need to make the repairs.

You get 1 retest for free if you complete the test by the “valid through" date; each test after that costs the original fee.

Repair Waivers

You can apply for a repair waiver with the VEIP if you meet EACH of the following requirements:

  • Your vehicle failed the initial emissions test, you made the necessary repairs, and the vehicle failed again.
  • Your repairs cost a minimum of $450 and you can provide receipts or invoices documenting the cost.
  • Any emissions-related repairs were made up to 30 days before the initial inspection and up to 120 days after the last inspection.

Complete and submit to the testing technician the back of your emissions test notice. If granted, your repair waiver is valid for 2 years from your original test date.
