Question: 1 / 400

What kind of safety check should be performed for tail lights?

Check they are clean and working properly

The correct choice highlights the importance of ensuring that tail lights are not only clean but also functioning properly. Cleanliness is crucial since dirty or obscured lights can diminish visibility, which is especially important for safety on the road. Working tail lights are essential for signaling your presence to other drivers, thereby preventing accidents and ensuring compliance with traffic regulations.

The focus on the condition and functionality of the tail lights reflects best practices for vehicle maintenance, which is critical for a commercial driver's responsibilities. Just ensuring they are turned on during the day does not address any potential visibility issues due to dirt or malfunction. The specifications regarding LED bulbs and warranty concerns do not directly impact the immediate functionality and safety of the tail lights, which is why those aspects are less relevant in this context.
