Driving in **adverse weather conditions** such as snow or rain can be more complicated and exhausting. These conditions affect visibility and tire grip, which means the vehicle needs more space to brake. This means the driver must be more alert and focused, which can increase **fatigue**.

- **Snow**: Visibility is reduced and tires have less grip, requiring more attention and effort to maintain control of the vehicle. Additionally, extra precautions should be taken, such as maintaining a greater safety distance and gradually reducing speed.

- **Rain**: Similar to snow, rain reduces visibility and tire grip. It is important to brake gently and maintain a greater distance from the vehicle in front. The first drops of rain can make the road especially slippery.

Due to these conditions, it is more likely that the driver will tire more quickly, making it **necessary to stop to rest** more frequently. This helps maintain safety and reduce the risk of accidents caused by fatigue.
