How do you properly perform a visual check to ensure the brake lights are working?

To perform a proper visual check to ensure that the brake lights are functioning correctly, it's important to test both the handbrake and the footbrake. According to German traffic regulations, ensuring that all brake lights are operational is crucial for road safety. By using the handbrake and footbrake in succession, you can confirm that both sets of brake lights illuminate when engaged. This method ensures that drivers behind you can see when you are slowing down or stopping, minimizing the risk of accidents.

If you only test one type of brake, you may miss a malfunction in the other system, which could put you and other road users at risk. Therefore, it's essential to use both brakes one after the other for a comprehensive check.
