Driving with **sleepiness** or **drowsiness** is very dangerous and can lead to traffic accidents. Drowsiness manifests with symptoms such as difficulty keeping your eyes open, blurred vision, frequent yawning, and loss of concentration. These symptoms indicate that the driver should stop driving immediately.

- **Stop and rest**: The best way to avoid an accident when you feel sleepy is to **park the vehicle in a safe place and sleep**. It is recommended to sleep for 20 to 30 minutes to regain alertness and continue the journey safely.

- **Avoid continuing to drive**: Reducing speed or driving on the shoulder is not safe, as it does not eliminate the risk of falling asleep at the wheel. Moreover, increasing speed to reach the destination faster is even more dangerous, as it increases the risk of an accident.

Therefore, the safest and most recommended option is to park and rest until you feel sufficiently alert to continue driving.
