I'll stick my neck out and say that International Equivalence is wrong

"National highways; state strategic road network.

the example of the Bruce Highway shows the error - the Bruce Highway carries 
the A1 marker where it is not M1

I used to get incredibly confused with primary = b and secondary = c
but this list got me better understanding the classification
