Underaged Drinking and Driving

My partner and I have dicided to focus on underaged drinking and driving. We chose to focus on this aspect of drinking and driving, because it is a huge tragedy when teenagers have died because of driving under the influence of alcohol. I also believe it's horrible that teenagers, who are in the beginning of their lives have died because of these simple, yet fatal mistakes of drinking, and then driving. The overall question we want to investigate while doing this project is: Why do teenages drink and drive, and how can it be prevented?
