**Fatigue at the wheel** is a significant risk factor that can lead to road accidents. When a driver is fatigued, they experience symptoms such as **difficulty concentrating**, **blurred vision**, and **slower reactions**. These symptoms indicate that the driver is in danger of suddenly falling asleep.

To avoid accidents, it is crucial that the driver **stops to rest** as soon as they feel the first symptoms of fatigue. Sleeping for 20 to 30 minutes may be enough to regain alertness. Additionally, it is advisable to rest every two hours or every 200 kilometers, even if you do not feel tired.

Some vehicles are equipped with **fatigue detectors**, which alert the driver through lights, sounds, or vibrations in the steering wheel when they detect that the driver is about to fall asleep. These systems are useful for preventing sleep from appearing unexpectedly, reinforcing the importance of stopping to rest as soon as possible.
