The consumption of **alcohol** while driving can have several negative effects on the driver's behavior. One of the most notable effects is that alcohol generates a **false confidence** in oneself. This means that the driver may feel more secure than they actually are, leading them to **take more risks** behind the wheel. This false security can cause the driver to commit more infractions and expose themselves to dangerous situations that could result in accidents.

Additionally, alcohol affects the brain and vision, which can influence the ability to make appropriate decisions and perceive the environment. However, the most direct effect related to false confidence is the tendency to behave more **aggressively or impulsively** with other drivers, thus increasing the risk of accidents. Therefore, it is crucial to avoid alcohol consumption before driving to maintain road safety.
