Calling all high school students! #X is a simple way to let your friends know you’re about to drive and can’t respond. Now before you get in the car and #X, your school could be in the running for an exclusive concert event!

All you have to do is tweet #X along with your high school’s team hashtag for a chance to win bragging rights and an exclusive concert at your school. Check out the current rankings to see if your high school is in the lead.
