Police say it all the time: seat belts save lives. But millions of students ride to and from school every day, without them.

Some recent high profile crashes, including some in Kentucky one in Alabama that killed four students has federal officials talking about the possibility of requiring seat belts on school buses.

The National Transportation Department in Washington, D.C. meets this week to look at information on seat belts. They're trying to determine if it would be safer for students to buckle up on the bus.

Those who support the idea point to recent crashes, like the one in Grant County back in January, as to why seat belts are needed.

Video from inside the bus showed how violently children inside were thrown around when the bus crashed. Two children were critically injured.

The bus driver, Angelynna Young, is now serving a prison sentence for driving the bus under the influence of drugs.

It's because of that crash, and others like it, that the Kentucky Department of Transportation says it supports the federal government's investigation into the possible need for seat belts on buses.

In Thursday's meeting in Washington, D.C., the transportation department met with not only safety officials but educators and bus manufacturers to figure out the best way to improve school bus safety.
