Georgia DDA 6-Hour Defensive Driver & Driver Improvement Practice Exam

The statement that at 80 mph, your risk is eight times that at 50 mph is supported by the principle that as speed increases, the severity and likelihood of an accident also increase significantly. This relationship is due to several factors: 1. **Kinetic Energy**: The energy of a moving vehicle increases with the square of its speed. This means that doubling the speed doesn't just double the energy; it actually quadruples it. Therefore, traveling at 80 mph, which is significantly faster than 50 mph, results in much higher kinetic energy that can contribute to more severe accidents. 2. **Reaction Times**: Higher speeds reduce the time drivers have to react to sudden changes in their environment, such as stopping suddenly or swerving to avoid an obstacle. At 80 mph, a driver's ability to respond effectively is compromised, leading to an increased risk of a fatal crash. 3. **Stopping Distance**: The distance required to stop a vehicle increases as speed increases. At higher speeds, even a slight delay in stopping can lead to a more severe impact in an accident. While other statements made in the question hint at the increased danger associated with speeding, they underestimate the actual risks involved. The correct answer highlights the dramatic escalation in risk that
