Can we use school bus signs?

Yes, buses being used to carry children under the age of 16 to and from school at the beginning and end of the day must display a special prescribed sign both at the front and the rear of the vehicle. 

Minibuses operated using section 19 permits which provide home-to-school transport should display school bus signs. 

The signs must have a black border enclosing a silhouette of two children on a yellow reflective background.  There should be a sign displayed at the front of the vehicle which must be at least 250mm × 250mm with the black border not more than 20mm wide and one displayed at the rear of the vehicle at least 400mm × 400mm with the black border not more than 30mm wide.
