**Alcohol** negatively affects the driver in several ways, especially in the **coordination of movements**. When a person consumes alcohol, it is distributed throughout the body via the bloodstream, primarily affecting the **brain** and **vision**. This can lead to a series of problems when driving.

- **Difficulty coordinating movements**: Alcohol makes it more difficult to coordinate body movements, which is crucial for safely operating a vehicle.
- **Slower reactions**: Additionally, reaction time increases, meaning the driver needs more time to respond to situations on the road.
- **Altered perception**: Alcohol also affects how the environment is perceived, making it harder to see traffic signs, judge distances, and avoid distractions.

For these reasons, it is clear that a driver under the influence of alcohol **will have more difficulty correctly coordinating their movements**, which increases the risk of accidents.
