Vehicle Inspection Report

When your emissions test is completed, whether the vehicle has passed or failed, you will be given a Vehicle Inspection Report (VIR). The VIR will contain information on your vehicle's performance on the various elements of the emissions test.

 Emissions:  Indicates if vehicle passed or failed for hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx). You may compare your readings to the emissions limits for passenger cars, light duty trucks or heavy duty trucks.

 Evaporative Systems:  Gas caps are tested on a pressurization device. A missing or leaky cap will causes the vehicle to fail the emissions test.

 Equipment Inspection:  All 1975 and newer vehicles are inspected for the presence and operation of the air injection system, catalytic converter(s), "check engine" indicator light, fuel filler neck restricter, and oxygen sensor. Vehicles are not penalized for lacking equipment they were not originally designed with.

 Smoke:  Smoke from the tailpipe must be less than 5% opacity at all times. Presence of smoke is an automatic fail regardless of emissions measurements.

 CFCs:  All pre-1995 model year vehicles with air conditioning systems are checked for chlorofluorocarbons (CFC) leakage. Advisory only.

 OBD Codes:  The Onboard Diagnostic system, found in recent model vehicles, provides codes explaining which engine components or emissions controls are not operating properly. Advisory only.

 Emissions Test Information:  Compares your vehicle's readings to the maximum allowable levels for the make and model year of your vehicle.

On the back of the Vehicle Inspection Report is the Vehicle Repair Form (VRF). If your vehicle fails the emissions inspection, take this form to your repair shop to fill out. The completed VRF is to be returned to the test center when you return for the retest. The information on the VRF is very important. It is used in grading the repair shop on its emissions repair effectiveness.

If your vehicle fails for excessive pollutant levels, you will also be given a Diagnostic Trace Report (DTR). This sheet contains a series of graphs with colored lines representing the levels of the various pollutants throughout the test. Bring this sheet to your repair shop along with your VIR. It is designed to give your repair technician useful information about your vehicle's emission patterns.
