What is one common characteristic of aggressive driving?

Frequent lane changes without signaling is a common characteristic of aggressive driving because it reflects a disregard for the safety of other drivers on the road. Aggressive drivers often maneuver their vehicles erratically and may not follow the standard safety protocols, such as using turn signals to indicate their intentions. This can increase the risk of accidents since other drivers are not made aware of sudden changes in direction.

In contrast, courteous behavior, respecting traffic signs and signals, and adhering to posted speed limits are indicative of safe and responsible driving practices that prioritize the safety and consideration of all road users. These behaviors are fundamental to maintaining order and safety on the roads, which are typically absent in aggressive driving scenarios.
