mission shall have authority, in disputed cases, to determine which roads
and streets upon which such motor vehicles are to be operated should be
included in the computation. The State Roads Commission, after mak-
ing such computation, shall forthwith certify the same to the Commissioner
of Motor Vehicles, whereupon the fee shown to be payable by said com-
putation shall immediately be paid by such motor vehicle owner to the
'Commissioner of Motor Vehicles.
