What is one effective strategy to avoid drowsy driving?

Driving with a companion is an effective strategy to avoid drowsy driving because having another person in the vehicle can help keep you alert and engaged. A companion can provide conversation, monitor your behavior for signs of drowsiness, and encourage breaks during long journeys. This social interaction can be a powerful deterrent against fatigue, as the presence of another person creates a more dynamic driving environment and can help maintain both drivers' attentiveness.

Other strategies like chewing gum, rolling down the window, or turning up the radio might offer temporary distraction or stimulation, but they do not address the root cause of drowsiness and are unlikely to increase alertness in the same way that companionship does. Chewing gum may keep your mouth busy, but it doesn't significantly impact overall focus. Rolling down the window may provide fresh air, which could help momentarily, but it's not a long-term solution to prevent fatigue. Similarly, turning up the radio could stimulate you for a brief period, but it may not be sufficient for sustained alertness on longer drives.
