SANFORD, Fla. -

The Seminole County Sheriff's Office on Monday issued crucial reminders and safety alerts involving drivers as students made their way to the bus stop for the first day of school.

“We want them to not only be mindful of the presence of the children but also of their driving habits and not texting while driving and making sure you pay attention to the roadway,” said Seminole County sheriff's Lt. Jason Bender.

There are 140 crossing guards posted around the county, and they will help thousands of students cross busy roads this year.

"Here in Seminole County we cross 5,000 children each and every day to and from school, so it's a very big task to undertake,” Bender said.

Since school let out for summer, SunRail has started operating, so extra crossing guards have been added. There are two SunRail tracks that now go through Seminole County.

“There can be 35 to 40 crossings north and southbound between SunRail, freight trains and Amtrak trains, so there is a high frequency of train crossings,” Bender said.

With busier tracks, Bender said parents who have children walking and biking to school should remind the kids to not only wear their helmet but fasten it. He also said children should not wearing headphones or ear buds while riding.
