Headlines about teenage drivers killing and injuring themselves or others while driving recklessly, including at high speeds, are becoming all too common. Today, Dr. Phil shows parents the reality of what many teens are doing behind the wheel of their vehicles. First, 19-year-old Nash and his father, Brent, both say they have the skills and performance cars to safely drive over 100 mph. Then, hear from Reina, a mother who says she had no idea her son Ajanni was part of the street racing culture until he lost his life in a fatal crash. Ajanni's best friend, Avery, says he stopped driving recklessly after the loss of his friend. Plus, social media star Damaury talks about taking police on a chase at speeds he claims were over 150 mph and his subsequent arrest. Has he changed his carefree driving ways? Dr. Phil also speaks with 16-year-old champion racecar driver Ashton Torgerson about why he would never drive anywhere off the racetrack at the speeds some of Dr. Phil's guests have driven. Lastly, Dr. Becca Weast, a research scientist from the Insurance Institute For Highway Safety, shares what parents can do to keep their teens safe behind the wheel.
