It's about the safety of the kids.
The annual School Bus Safety Video Contest is open to students grade primary to 12.
Trish Smith with the Nova Scotia School Boards Association says they're trying to raise awareness around school bus safety, specifically when the bus's stop arm is extended.
"We just need to continue to hammer away at this message until it becomes incredibly common knowledge that you do not pass a school bus when it is stopped."
Smith also says most campaigns are more effective when younger groups are reached.
