What should vehicle owners do to prepare for an emissions inspection?

Preparing for an emissions inspection involves taking steps to ensure that the vehicle is in proper working order, particularly in relation to its emissions system. This includes checking and repairing any known issues with components like the catalytic converter, oxygen sensors, or exhaust system, which can significantly affect emissions output. A well-functioning emissions system is crucial for passing the inspection, as vehicles that emit too many pollutants may fail.

While filling the fuel tank can influence the inspection depending on specific testing protocols, ensuring that the vehicle’s emissions system is functioning correctly is the most critical factor. Similarly, properly inflated tires and a clean appearance of the vehicle, while important for overall vehicle maintenance, do not directly impact the emissions measurement during an inspection.
