The vehicle will be rejected if what is not functioning properly?

The vehicle will be rejected if the lights are not functioning properly because working lights are crucial for the safety of the vehicle and its operation on the road. Proper functioning of headlights, taillights, brake lights, and turn signals is essential for visibility and communication with other drivers. If any of these lights malfunction, they can lead to dangerous situations, such as not being seen in low-light conditions or failing to signal turns and stops, which can result in accidents. Therefore, ensuring that all the vehicle’s lights are operational is a critical aspect of the Virginia state inspection process.

In contrast, while the gearshift indicator, horn, and battery level are important for vehicle operation, they do not have the same immediate impact on safety related to visibility and communication with other vehicles on the road. Thus, the requirement for functioning lights takes precedence over these other components during the inspection.
