Teresa Underwood was driving east on West Lamar Alexander Parkway just inside the Blount County line when she apparently ran off the road and overcorrected, which caused her to go over the two east bound lanes, median and two westbound lands.

Underwood was conscious after the accident, although hanging from her seat belt, which was credited with saving her life.
She suffered a gash to her wrist and was bleeding so much that officers speculated she nicked a vein
