A 2017 study found that graduated license programs have been instrumental in reducing car crashes among 16 and 17-year-olds.
In fact, it's been so successful that some states are considering adopting graduated license programs for 18 to 20-year-olds who are becoming first-time drivers.
As a way to help teens slowly gain driving responsibilities one step at a time, states adopted graduated license programs.
These programs have restrictions for newly licensed drivers, such as a limit on the number of passengers or a curfew.
Research shows many parents aren't good at teaching kids to become safe drivers.So it's important for parents to talk to teens about the risks of distracted driving.And if a teen is caught sending messages or using a cellphone while driving, there should be clear consequences.Restrictions on night driving may reduce teen car crashes by 19 percent.Each state determines what hours to restrict teens from driving.
