According to the article, what happens to teenagers who get insufficient sleep?

Teenagers who experience the lack of sleep may experience drowsiness or fatigue. Teenagers may also experience physical inactivity due to fatigue. 

Teenagers are asked to not drive when they lack sleep, because lack of sleep is one of the major causes of major road accidents that leads to many fatalities. Which is why, parents are tasked to prohibit their children from driving, when they lack sleep.
