Many kids aren't buckled into cars properly.
Researchers at the University of Michigan analyzed data on more than 21,000 children who were observed in cars pulling into gas stations, restaurants and child care centers.
Fewer than 2-percent used a booster seat after age 7, even though many experts recommend boosters at least until a child reaches 57-inches, the average height of an 11-year-old.
Also, many children over age 6 sat in the front seat. It's recommended they stay in the back until their 13th birthday.
A higher percentage of minority children were transitioned to seat belts prematurely, according to the study.
