Driving on a **road in poor condition** can contribute to the driver's **fatigue**. This is because the condition of the road is one of the factors that influence the driver's state and can cause fatigue.

- **Fatigue** is a significant risk that can lead to road accidents. It can be both **physical** and **psychological**. Physical fatigue generates a feeling of tiredness, while psychological fatigue makes concentration difficult.

- Symptoms of fatigue include difficulty concentrating, heaviness in the eyes, slower movements, and a feeling of nervousness and irritability. These symptoms can intensify when driving on a road in poor condition, as the driver needs to be more alert and make more efforts to maintain control of the vehicle.

Therefore, it is important to recognize that a road in poor condition can increase fatigue, affecting driving safety.
