**Alcohol** has a significant impact on a driver's **decision-making process**. When you consume alcohol, your ability to **see the environment** is affected. This includes poorer perception of **traffic signs**, **traffic lights**, and the **distance** to other vehicles. Additionally, alcohol can increase the **possibility of distractions** with elements of the environment and make you more easily dazzled by the lights of other vehicles.

Alcohol also affects the driver's **behavior**, generating a false sense of security, which can lead to making **impulsive** or **aggressive decisions**. This increases the risk of making mistakes that can cause accidents. Furthermore, alcohol slows down **reaction time** and increases the likelihood of making **poor decisions** or not knowing how to execute them correctly.

Therefore, even small amounts of alcohol can significantly alter the **perception of the traffic environment** and the ability to make appropriate decisions at the wheel, making driving much more dangerous.
