Why must all lights be operational during an inspection?

The requirement for all lights to be operational during an inspection is fundamentally connected to visibility and safety on the road. Proper functioning vehicle lights—including headlights, taillights, brake lights, turn signals, and reverse lights—are crucial for safe driving. They enable drivers to see the road and be seen by others, particularly in low-light conditions or adverse weather. Non-operational lights can lead to dangerous situations, such as rear-end collisions because other drivers may not be aware of the vehicle's actions.

The focus during vehicle inspections is prioritizing safety standards, and ensuring that all lighting components are operational significantly contributes to preventing accidents and enhancing overall road safety.
