The kids go back to school Monday, DeKalb, and that means buses will be back on the roads.

To keep you prepared, the DeKalb County Police Department released a helpful diagram on its Twitter page.

The post is titled “Driver Homework” and encourages people behind the wheel to “slow down and keep our kids safe.”

The image explains when and where to stop your vehicle for a school bus. In most cases, vehicles driving in both directions are required to stop when the school bus stops, including on a four-lane road with no median separation.

Divided highways of four or more lanes are the only areas where traffic on the opposite side of the road does not stop for a school bus.

“Cars passing a stopped bus may not see the student, who can be obstructed by the stopped bus,” said DeKalb police spokeswoman Officer Shiera Campbell. “Stopping for a bus saves lives.”
