What happens when you fail inspection for a gas cap?

When a vehicle fails inspection due to a faulty gas cap, it typically indicates a problem with the evaporative emissions system, which can lead to fuel vapor leaks. The owner is usually required to replace or repair the gas cap to ensure a proper seal. After addressing the issue, the vehicle will need to be re-inspected to pass and receive certification. Failing to rectify this can result in continued driving restrictions and potential fines.
