To prevent drowsiness during continuous driving on an interstate road, what should drivers do?

The correct choice, which emphasizes the importance of keeping your eyes shifting, is beneficial because it helps maintain focus and reduces monotony during long drives. When driving for extended periods, especially on highways where the scenery may not change much, it is easy for a driver’s attention to wane and fatigue to set in. Shifting your gaze can refer to consciously looking around at different parts of the road, checking mirrors, and engaging with the environment, which can help a driver stay alert and focused.

While the other options may seem like viable alternatives, they do not effectively address the risk of drowsiness. Shifting gears frequently does not contribute to alertness or engagement in driving; it is simply a function of maintaining control of the vehicle. Listening to loud music might provide some stimulation, but it could also become a distraction or create an overwhelming auditory experience that takes attention away from driving. Pulling over for breaks every hour is certainly a useful suggestion for long-distance travel but may not directly prevent drowsiness during continuous driving, especially if the driver does not feel the need to stop yet. Therefore, keeping your eyes moving is a practical approach to enhancing alertness and reducing the chance of fatigue on the road.
