Dawn is at 5 AM. The question is that I can either leave to my Doctors appointment at 5 AM, and not get stuck in traffic and I will reach my destination with time to daven with a Minyan before my appointment, or I can daven before I leave, but I will get stuck in traffic and possibly miss my appointment. Can I leave at 5 AM, before I daven? Answer: Yes, just first recite the Birchas Hashachar and then travel.
