What must be documented following the completion of an emissions test?

After an emissions test, it is crucial to document the results of the test and any repairs made. This documentation is essential as it provides a clear record of the vehicle's emissions status, ensuring compliance with environmental regulations and standards. It allows for tracking the vehicle’s performance over time and serves as evidence of necessary fixes to maintain or improve emissions control.

Proper documentation includes details such as numerical test results, any failed components, and specific repairs or adjustments that were executed to bring the vehicle back into compliance. This information is vital for regulatory agencies, ensuring that vehicles on the road meet the required emissions standards, and it may also come into play during inspections or when selling the vehicle.

While other options may be important in specific contexts, they do not hold the same regulatory significance as the results of the emissions test and any repairs made.
