Have you ever seen mommy or daddy drink something called alcohol? It's a drink that can make grown-ups feel funny and happy, but it's not safe for kids to drink. When adults drink alcohol, it goes into their blood and can make it hard for them to think or make good choices.
Blood alcohol concentration (BAC) is a way to measure how much alcohol is in someone's blood. It's kind of like measuring how much sugar is in a glass of lemonade. The higher the BAC, the more alcohol is in their blood and the more it can affect their thinking, movement, and behavior.
For grown-ups, it's illegal to drive if their BAC is too high because they can't think or react quickly enough to drive safely. It's important for grown-ups to be responsible and not drink too much alcohol so they can stay safe and make good choices. And remember, alcohol is not safe for kids to drink!
