What is required for brake lights to pass inspection?

For brake lights to pass inspection, it is essential for both rear lights to function correctly. This requirement ensures that the vehicle provides maximum visibility to drivers behind it when the brakes are engaged. Having both brake lights operational is crucial because if only one brake light is functioning, it could lead to confusion for other drivers regarding the braking intentions of the vehicle. The proper signaling of intentions on the road promotes safety and reduces the risk of accidents. Ensuring both lights work together helps maintain a standard that minimizes miscommunication on the road.
