How should the inspector proceed in cases where the emission control label is missing or illegible?

• A. Stop the inspection
• B. Continue the inspection provided that the required emission controls can be determined using other sources
• C. Document as failure and end inspection
• D. Request manufacturer data sheet

Answer: (B)

When the emission control label is missing or illegible, you don’t have to halt the inspection. The important step is to verify what emission controls are required for that vehicle through other reliable sources. You can consult the VIN, the owner’s manual or service data, manufacturer data sheets, or official databases to determine the specific controls that should be present. If you can establish the required controls from these sources, you may continue with the inspection and document that you confirmed them via alternative references. Stopping the inspection or marking it as a complete failure isn’t necessary if a verifiable source exists. The option to request a manufacturer data sheet is helpful, but it’s part of the process of confirming controls; the key is being able to determine the controls from other sources and proceed.
