NHSA Georgia Driver's Ed Practice Exam

Aggressive driving is characterized by behaviors such as rapid acceleration, hard braking, and rapid lane changes. These driving habits often result in excessive wear on various vehicle components, including the brakes, tires, and engine. This is because aggressive maneuvers increase stress on the car's systems, leading to more frequent maintenance needs and potentially shorter vehicle lifespan.

In contrast, the other options do not align with the effects of aggressive driving. Increased fuel efficiency typically results from smooth driving patterns that avoid sudden stops and starts. Improved vehicle performance and higher safety ratings are also associated with careful and responsible driving rather than aggressive actions, which tend to compromise both performance and safety. Thus, excessive wear on parts is the logical consequence of aggressive driving behaviors.
