Driving for a long time without resting can make **driving more dangerous**. This is because the driver may experience **fatigue** and **drowsiness**, two conditions that negatively affect their ability to drive safely.

- **Fatigue**: When a driver is fatigued, they may have difficulty concentrating on the road, feel heavy-eyed, have poor hearing, and experience a sensation of pressure in the head. Additionally, movements become slower, and there is greater difficulty in making decisions and reacting quickly. All of this increases the risk of accidents.

- **Drowsiness**: Drowsiness causes difficulty in keeping the head upright and the eyes open, blurred vision, and loss of concentration. It can also lead to the driver being easily distracted, drifting out of their lane, or not paying attention to traffic signals. These symptoms are dangerous and can result in risky situations on the road.

Therefore, it is crucial that drivers take regular breaks to avoid these symptoms and maintain driving safety.
