There seems to be some confusion over when to stop for an oncoming school bus, now that school is back in session. Murfreesboro Police Chief Michael Bowen stated...
Again, when there is a physical divide on a highway like grass, concrete or trees you do not stop for oncoming school buses. When there is not a physical divide and only lines on a highway, you must stop for oncoming school buses.
Another question on stopping... When to stop for funeral processions?
However, the funeral procession does have the right of way at intersections so that the entire procession can remain intact.
