It's the start of a new school year, and safety is a top priority.

School's been out for the summer, but now it is time for students to head back to class, meaning lots more cars will pack Highway 25E twice a day.

"It's nerve-wracking the first day," said Darrell York.

York is a bus driver. He's been driving for many years.

"My first bus stop will be up here in a minute," said York.

Day one of the school year means a few empty seats though.

"the first day a lot of parents bring them," said York.

With buses on the road and cars lining up, that adds up to extra traffic on the highway.

"Everyone needs to slow down, and everybody needs to watch out especially in this time of year," said Margie Hensley, a grandparent.

Hensley said she worries about people speeding down Highway 25E.

"Use caution when they enter a school zone - reduce their speed," said Shane Jacobs, with Kentucky State Police.

Police said many people do not realize that school is back in session.

And school leaders point out traffic tends to remain tied up until families get in a routine.

"Be patient with us. There is a lot of traffic in the afternoon and morning," said Greg Wilson, Principal of Bell Central School.

That's a sure sign that lots of precious cargo could be crossing the road right in front of you.

Police said over the next month they will be checking speed in these school zones.

School leaders in Bell County conduct safety training at the beginning of the year with some of the youngest students to make sure they know how to safely get on and off the bus.
