INDIANAPOLIS (AP): Officials of some Indiana driver's education schools say they're worried changes in state law are leading to more young drivers getting their licenses without professional training.

Indiana's graduated license law adopted in 2010 allows teens to obtain a license at 16 years and six months with driver's education courses and 16 years and nine months without.

Drive Zone school president Tom Zachary told a state legislative committee Tuesday that's the smallest time gap in the country. Zachary says he believes Indiana is going the wrong direction with more teens are behind the wheel without training.

Sen. Brent Waltz of Greenwood said he believed driver's education schools might need to reinvent themselves rather than seek another change of state law.
