What is the likely effect if a teen uses alcohol while driving?

Using alcohol while driving significantly increases the risk of accidents for a teen. Alcohol impairs various critical functions needed for safe driving, including judgment, coordination, reaction time, and reflexes. It can lead to an inability to make sound decisions, which are essential for assessing situations on the road. For teens, who may have less experience behind the wheel, this impairment can be particularly dangerous. As such, the likelihood of accidents rises dramatically when alcohol is involved, making it crucial for young drivers to avoid alcohol consumption entirely while driving.

The other options suggest outcomes that are misleading. Safer driving, improved confidence, and enhanced vision do not reflect the reality of the effects of alcohol on driving abilities. In fact, any level of alcohol consumption diminishes the driver's capacity to operate a vehicle safely, highlighting the importance of understanding the dangers associated with drinking and driving.
