Which practice is essential for dealing with unexpected road hazards?

The correct answer emphasizes the importance of maintaining control and responsiveness in the face of unexpected road hazards. Swerving or applying brakes as needed allows a rider to quickly adjust to sudden obstacles, changes in road conditions, or other dangers that may appear unexpectedly. This approach promotes safety by enabling the rider to choose the most appropriate response to avert a potential accident.

Being attentive and adapting to the circumstances is key in managing risks effectively while riding. Therefore, having the ability to maneuver—whether by changing direction or adjusting speed—provides the flexibility necessary to respond to emergencies.

In contrast to this, some other practices do not contribute effectively to safety in such situations. For instance, relying solely on brakes might lead to loss of control, particularly if it causes the wheels to lock up. Riding close to the vehicle in front can limit a rider's reaction time and increase the risk of a collision. Driving at high speeds reduces reaction time and makes it much harder to navigate around unexpected hazards safely. The correct practice focuses on the ability to react intelligently and safely to any changes in the riding environment.
