VicRoads Learner Permit Practice Test

Excessive speed significantly decreases your ability to respond to hazards and increases stopping distance, making option B the correct choice. When driving at high speeds, a driver has less time to observe and react to changing road conditions, obstacles, or other vehicles. This delayed response can lead to dangerous situations, as the driver's ability to make quick decisions is compromised.

Moreover, the stopping distance of a vehicle increases with speed due to the physics involved in stopping motion. As speed increases, the distance required to bring the vehicle to a complete stop grows significantly. The greater the speed, the more time and distance it takes to stop. Therefore, when traveling at excessive speeds, not only does a driver struggle to react promptly to hazards, but they also face the risk of not being able to stop in time to avoid a collision.

Other options do not accurately reflect the reality of driving at high speeds. For instance, suggesting that excessive speed enhances control or improves response times is misleading, as it neglects the fundamental physics of driving dynamics. Additionally, the idea that excessive speed has no effect on control is incorrect, as speed drastically influences a driver's capability to manage their vehicle effectively. Finally, while speed can have an effect on fuel consumption, higher speeds generally lead to reduced fuel
