What is a helpful tip for maintaining alertness while driving?

Taking frequent breaks is a crucial tip for maintaining alertness while driving, particularly on long trips. When you drive for extended periods without a break, fatigue can set in, leading to decreased attention and slower reaction times. Breaks allow drivers to stretch, hydrate, and refresh their minds, thereby reducing the risk of drowsiness behind the wheel. Regular pauses every couple of hours or when you start feeling tired help ensure that you stay alert and engaged with the driving task.

The other options, while they may have some relevance to driving comfort or safety, do not directly contribute to maintaining alertness as effectively as taking breaks. For instance, driving with the radio off or keeping windows closed might help create a quieter environment but doesn’t necessarily combat fatigue. Slower speeds can lead to safer driving in certain situations but don't inherently help in keeping a driver alert. Frequent breaks, however, directly allow for physical and mental rejuvenation, promoting overall alertness and safety on the road.
