How can fatigue be prevented on a long journey?

You answered correctly. Fatigue on a long journey can be prevented by taking regular breaks and performing light exercises during stops, such as stretching or walking around. These actions help your body and mind recover, keeping you alert and reducing the risk of microsleep or slower reaction times. Simply drinking coffee and skipping breaks is not a safe way to avoid tiredness, because caffeine cannot fully replace the recuperating effect of proper rest. Regular pauses and physical activity are essential for safe driving on long trips.
