1. All vehicles with a model year 1996 or newer must have an On-Board Diagnostics (OBD) test as part of the inspection process. OBD is a computer-based system built into all 1996 and newer light-duty passenger vehicles to monitor the performance of some of the engine's major components, including emission control components. 2. If your vehicle passes the safety inspection but fails the OBD inspection and you cannot afford the repairs to the emissions, you may be eligible for an Economic Hardship Waiver to allow more time to save the money to complete the repairs.
