**Fatigue** at the wheel is a state that negatively affects the ability to drive safely. When a driver is fatigued, they experience several symptoms that can jeopardize their safety and that of others on the road.

- **Prolongation of reaction time**: One of the most critical effects of fatigue is that the driver takes longer to react to situations on the road. This means that if an unforeseen event arises, the driver will not be able to respond with the necessary speed, increasing the risk of accidents.

- **Symptoms of fatigue**: Fatigue manifests through signs such as difficulty concentrating, slower movements, and a general feeling of tiredness. These symptoms contribute to the prolongation of reaction time, as the driver is not in their optimal state to make quick and effective decisions.

- **Associated risks**: Fatigue is a significant risk factor in driving, as it can be both physical and psychological. Physical fatigue causes tiredness, while psychological fatigue makes concentration difficult, both contributing to a slower response to traffic situations.

For these reasons, it is crucial to recognize the symptoms of fatigue and take measures to rest before continuing to drive, thus ensuring safer driving.
