When a school bus is unloading or picking up kids they will have their stop sign out, and that's your cue to stop.

If you don't, you could face a hefty fine.

"You have to stop a minimum of five metres on either side of the school bus," said Constable Rob Tuff. "Failing to do so could result in a fine of $672 and two demerit points on your license."

Many school buses these days are also equipped with cameras.

"If you do happen to go past a school bus while it's stopped and the stop sign is out, you could be caught on camera," added Tuff.
