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

To properly check that your brake lights are functioning, you should test both the handbrake and the footbrake one after the other. This ensures that both systems are operational, as some vehicles may have separate indicators for each brake type. According to German traffic regulations, it's important that all lights, including brake lights, are in working order for safety reasons. This visual check helps prevent accidents by ensuring that other drivers can see when you are slowing down or stopping. Therefore, testing both the handbrake and footbrake separately allows you to confirm that your vehicle is safe for use on the road.
