How can you prevent fatigue during long driving hours?

Take regular breaks
Stay caffeinated throughout the drive
Only drive during daylight hours
Use cruise control constantly

The correct answer is: Take regular breaks

Taking regular breaks is crucial for preventing fatigue during long driving hours. When operating a vehicle for extended periods, the driver’s mental and physical stamina can significantly decrease. Regular breaks allow the driver to step away from the road, stretch, hydrate, and rest, which helps to recharge both physically and mentally. This practice can enhance alertness and improve overall safety on the road. While staying caffeinated might seem like a solution, relying solely on caffeine without breaks can lead to a crash later when the effects wear off. Driving only during daylight hours can help reduce fatigue to a degree, but it does not address the issue of fatigue that can occur during long stretches of driving regardless of the time of day. Using cruise control can help maintain speed and allow the driver to relax their foot, but it does not prevent fatigue because it can encourage longer periods of constant driving without breaks. Therefore, taking regular breaks is the most effective strategy for managing fatigue and maintaining focus while driving.
