What is necessary if a vehicle fails its safety inspection?

When a vehicle fails its safety inspection, it is required to be repaired and undergo a re-inspection. This ensures that any deficiencies are addressed and the vehicle meets the safety standards required for operation on public roads. The safety inspection process is designed to protect both the driver and the general public by ensuring that all vehicles are safe to operate. Without repairing the identified issues and undergoing a re-inspection, the vehicle cannot be declared safe, which could result in unsafe conditions on the road.

This requirement emphasizes the importance of maintaining vehicle safety and ensures compliance with the regulations set by the state. The other options do not align with the protocols in place for vehicle safety inspections, as they either suggest operating a vehicle that is not safe or imply that the inspection process is meaningless after a failure.
