YULEE, Fla. -- Summer vacation has officially ended for students in Nassau County.

Students woke up bright and early Thursday morning for the first day of a new school year.

Today was also a busy morning at the "bus barn" for the transportation department of the Nassau County School District.

Drivers started showing up before 6 a.m. to complete the first of two safety checks drivers are required to do every day.

In Nassau County, school bus drivers provide service to every school and complete a total of four routes daily.

Two routes occur in the morning and two in the afternoon. In between, they are allowed to run personal errands or go home.

Shelly Macomber is starting her third full school year as a school bus driver.

She said student safety is every drivers' first priority, but that the job comes with a lot of rewarding benefits.

Macomber said she bonds with the children and loves spending time with them.

Thursday also marked the first day back to school for students in Glynn County, Georgia.
