ok...........John Doe is out walking his dog. A drunk driver swings over and runs over John Doe, but misses the dog. The unhurt dog runs home as fast as he can and waits at the door for John Doe. Now John Doe is laying on the side of the road hurt and unconscious. EMS comes and takes John to the hospital. John has no other ID on him but his FL drivers license. The police run his DL number and it gives them his sister as his emergency contact. They call his sister and tells her that John was found hurt on the side of the road unconscious, she ask them what happened to his dog, They say there was no dog. So she runs to Johns house and finds his dog sitting on the steps and really glad to see her. Now had John not had her info in his DL the dog could have had to sit on the step in th hot Florida sun for days before anyone knew to come check on him. Thats why you need emergency numbers connected to your drivers license.
