Which behavior is considered a sign of negligent driving?

Answer: B — Frequent lane changes without signaling

Frequent lane changes without signaling is clearly indicative of negligent driving behavior. This action can create dangerous situations on the roadway, as it disregards the importance of indicating intentions to other drivers. Signaling is crucial for safe driving because it allows other motorists to anticipate your movements, thereby reducing the risk of collisions. Negligent driving is characterized by a lack of care that a reasonably prudent driver would observe in similar circumstances. By changing lanes without signaling, a driver fails to communicate their intentions and may cause confusion and danger for other road users. This type of behavior can lead to accidents and is often subject to enforcement by law enforcement agencies. In contrast, adhering to speed limits, using headlights during poor visibility, and maintaining a safe following distance are all examples of responsible driving behaviors that prioritize safety and compliance with traffic laws. They reflect a commitment to protecting oneself and others on the road.
