What type of behavior is NOT a vigilance problem when driving?

Maintaining a safe following distance is a fundamental aspect of safe driving behavior and is not considered a vigilance problem. Vigilance problems typically involve a lack of attention, awareness, or responsiveness while driving, leading to unsafe conditions on the road.

In contrast, maintaining a safe following distance indicates that the driver is attentive to the traffic around them and is taking appropriate measures to ensure they have enough reaction time in case of sudden stops or emergencies. This behavior reflects good situational awareness and helps prevent collisions, thereby enhancing overall road safety.

On the other hand, behaviors such as slow response to traffic signals or stopping for no apparent reason can indicate issues with attentiveness or situational awareness, categorizing them as vigilance problems. Driving without headlights, especially at night, also reflects a lack of awareness of the driving conditions and poses significant risks to both the driver and others on the road.
