To help relieve fatigue on a trip, stopping and resting every 2 hours is the recommended approach. This practice addresses driver fatigue by allowing the driver to take a break from the demanding task of driving, which can be mentally and physically exhausting. Short breaks provide an opportunity to stretch, hydrate, and re-energize, facilitating better focus and alertness when returning to the road.

Regular stops not only help combat fatigue but also contribute to overall safety by reducing the risk of drowsy driving, which is a significant factor in automobile accidents. By taking breaks every couple of hours, drivers can maintain better mental acuity and reaction times, which are crucial for safe driving.

In contrast, options such as changing drivers every hour could be impractical if there isn't another licensed driver available, and playing music loudly might not effectively address fatigue—it could even be distracting. Eating heavy meals can lead to sleepiness, as the body diverts energy to digestion, which detracts from alert driving. Therefore, the best approach to staying alert and safe on a long trip is to make it a habit to stop and rest regularly.
