DUBOIS CO., IN (WFIE) - As kids head back to class, deputies with the Dubois County Sheriff's Office will be watching drivers.
They say they'll be looking for anyone breaking state law when it comes to passing a stopped school bus.
In Indiana, drivers must stop when a bus has its red flashing lights on and its stop arm out.
Todd Ringle with Indiana State Police says the exception is on roads divided by a grassy median or concrete barrier.
On those divided roads, only cars going the same direction as the bus have to stop.
If a bus has its yellow flashing lights on, it's time to slow down and get ready to stop.
In Kentucky, drivers going any direction must stop if a bus has its lights on and its stop arm out and is picking up or dropping off kids.
Only drivers going the opposite direction on a highway with four or more lanes can keep going.
Stopped drivers can get moving again when the bus does.
