What action can you take to improve your alertness while driving?

Taking regular breaks is a vital action to enhance your alertness while driving. Long periods of driving can lead to fatigue, resulting in decreased concentration and slower reaction times. By stopping to take breaks, you allow your body and mind to rest, which can help revitalize your focus and reduce the risk of drowsiness. Regular breaks not only provide an opportunity to stretch and hydrate but also offer a chance to engage in brief periods of physical activity, which can further improve alertness.

Other options, while they might have some merits, do not effectively address the problem of fatigue and reduced alertness over extended driving periods. For instance, merely drinking coffee may provide a temporary boost in alertness due to caffeine, but it does not combat the physical fatigue that comes from prolonged driving. Similarly, leaving the windows closed or driving with the radio off may create a more controlled environment but does not actively refresh the driver or help prevent fatigue. Regular breaks, on the other hand, are a proactive approach to maintaining alertness and ensuring safe driving practices.
