260. Except as hereinafter provided, each and every such motor
vehicle so registered shall operate only on the route and schedule set forth
in said application during the year for which said license is issued.

It shall be the duty of the Commissioner of Motor Vehicles, upon the
presentation of a permit from the Public Service Commission of Mary-
land, authorizing the motor vehicle owner to operate on a certain route,
to furnish the motor vehicle owner with a distinguishing plate or marker.

No such motor vehicle owner shall change said schedule or route of his
motor vehicle during any year for which a certificate has been issued,
without a permit, in writing, made in duplicate, from the Public Service
Commission of Maryland, a copy of which shall be sent to the Commis-
sioner of Motor Vehicles before said schedule is changed.

Nothing in this sub-title shall be construed to prevent an owner or
operator of such regularly licensed vehicles from replacing in an emer-
gency such vehicles by a substitute vehicle in order to maintain the
schedule approved as herein provided, or in an emergency from operating,
temporarily, reserve vehicles on such routes and schedules, approved as
aforesaid for the public accommodation, in which event immediate notifi-
cation shall be given the Commissioner of Motor Vehicles of the number of
trucks, license plate numbers displayed and destination of all such emer-
gency vehicles.

In cases where certificates have been issued to such motor vehicle owner
for more than one route, all motor vehicles of the same weight, including
reserve or substitute vehicles, which have been registered for use upon
either or any of said routes, may be used interchangeably upon either or
any of said routes.

The operations upon any route may be conducted with greater fre-
quency then prescribed by the approved schedule without obtaining per-
mission therefor from the Public Service Commission, provided, however,
that the approved schedule shall be strictly maintained and adhered to,
until changed with the permission of the Public Service Commission.
Whenever, in the opinion of the Public Service Commission, it will be
prejudicial to the public welfare and convenience, to permit operations
to be conducted upon any route with greater frequency than prescribed
by the approved schedule, said Commission may limit this privilege in
whatever manner it may deem proper or deny the said privilege altogether,
either at the time of the issuance of the permit or at any time thereafter.
