What should drivers be especially cautious of during twilight hours?

During twilight hours, visibility can be significantly reduced, making it difficult for drivers to see certain hazards on the road. While all the options listed present their own concerns, the focus on vehicles without lights is particularly pertinent during this time. Some drivers may forget to turn on their vehicle's headlights or may not have functioning lights. This can create dangerous situations as these vehicles can be harder to see, increasing the risk of collisions.

In low-light conditions, the failure to notice a vehicle that is not adequately illuminated could lead to an accident. It's crucial for drivers to remain vigilant and scan the road for these potential hazards, particularly during the transitional period between day and night when light conditions can change rapidly. This emphasizes the need for enhanced awareness while driving during twilight and the importance of ensuring that one’s own vehicle lights are functioning properly.
