What aspect of driving safety is improved by effective steering?

Effective steering significantly enhances obstacle avoidance, which is a crucial aspect of driving safety. When a driver is adept at steering, they can maneuver the vehicle more accurately and quickly in response to potential hazards or obstacles on the road. This skill allows the driver to make precise adjustments to their path, helping to navigate around unexpected obstacles, such as pedestrians, other vehicles, or road debris, thereby reducing the likelihood of collisions.

Good steering control involves not just the ability to turn the steering wheel, but also understanding the vehicle's dynamics and how it will respond to steering inputs. The quicker and more accurately a driver can steer away from danger, the safer the driving experience will be overall.

While the other options relate to different aspects of vehicle control and safety—such as managing speed with acceleration, ensuring stops with braking, or maintaining visibility—they do not directly correlate to the immediate action of steering in response to obstacles. Thus, effective steering is pivotal in enhancing a driver's ability to avoid hazards, making it the correct choice.
