What is an indication of a reckless driver?

Answer: B — Frequent lane changes without signaling

Frequent lane changes without signaling is a clear indication of a reckless driver because it demonstrates a disregard for the rules of the road and the safety of others. Drivers who change lanes abruptly and without signaling can create uncertainty and danger for other vehicles on the road. It shows a lack of communication, which is essential for maintaining safety in driving. Proper signaling is crucial as it allows surrounding drivers to anticipate and react to a vehicle's intent, thereby preventing potential accidents and promoting smoother traffic flow. In contrast, the other options either depict safe driving behaviors or are often misunderstood; driving below the speed limit may sometimes be safe, using cruise control can maintain a safe speed, and keeping both hands on the wheel promotes control and stability while driving.
