What is the consequence of driving with malfunctioning brake lights?

Driving with malfunctioning brake lights poses a heightened risk of accidents because these lights are critical for signaling to other drivers your intention to stop or slow down. When brake lights fail to illuminate, following drivers may not realize you are reducing speed or coming to a stop. This lack of communication can lead to rear-end collisions, as other drivers may not have adequate time to react. Proper functioning brake lights are essential for maintaining safety on the road and ensuring that all drivers are aware of one another's movements. In contrast, the other choices do not accurately reflect the implications of defective brake lights. Increased visibility in poor weather is clearly contradictory, while heightened braking efficiency and the notion of having no impact on driving are both misleading as they suggest that malfunctioning lights would somehow improve safety or function.
