Missouri is getting ready to restrict driving privileges for young teenagers soon. Director of the state department of revenue, Quentin Wilson, says the tighter restrictions have worked elsewhere, where accident rates for 16-year-olds have dropped 20% in some states. Missouri teens won’t be able to get driver’s licenses until they’ve used a driver’s permit for six months. While they’re using the permit, they have to have a parent or guardian in the car. Once they’re licensed–and until they turn 18– they can only drive late at night under limited circumstances. They also have to wear a seatbelt all the time. The changes go into effect January first.
