Who must perform the repairs on a vehicle after it fails inspection?

The answer is based on the fact that, after a vehicle fails inspection, repairs can be carried out by any individual, regardless of their certification or professional standing. This flexibility allows vehicle owners to have repairs done in a cost-effective manner by family members, friends, or themselves if they possess the necessary skills.

While certified mechanics may often be chosen for repairs due to their expertise and training, it is not a requirement that only they can perform the necessary work. This option also affords vehicle owners the freedom to seek help from those they trust or to attempt repairs independently, as long as the vehicle meets the necessary standards before it can be re-inspected.

The other options imply restrictions on who is allowed to conduct repairs, which is not in line with the regulations that allow for broader flexibility in choosing who can fix the issues causing the vehicle to fail inspection.
