During VI, what action is taken if the emission-control label is missing or illegible?

• A. It is ignored as long as other items pass.
• B. It is noted for future maintenance.
• C. It is considered a failure because the emission-label is not legible or missing.
• D. The vehicle is allowed to proceed for test only.

Answer: (C)

The action hinges on the requirement that the emission-control label be present and legible to confirm the vehicle has the proper emission-control equipment. If the label is missing or illegible, you can’t verify what controls are installed or whether they’re intact, so that item fails the visual inspection. This isn’t something you can overlook or defer to future maintenance, and it doesn’t permit the vehicle to proceed with the test. The label’s presence and readability are essential to establish that the emission-control system is in place and traceable, which is why the correct outcome is a failure for missing or unreadable labeling.
