324 ARTICLE 56.

1929, ch. 257.

189A. The Commissioner of Motor Vehicles may require the inspection
of any motor vehicle or trailer to determine whether or not it is unsafe
or improperly equipped or otherwise unfit to be operated. Such inspec-
tion shall be made at such times and in such manner as the Commissioner
of Motor Vehicles may specify. The Commissioner of Motor Vehicles
may authorize properly qualified persons to make inspections, without
expense to the State, or to the owner of the motor vehicle at stations
designated by him, and he may at any time revoke such authorization or
designation. There shall be at least one inspection station in each legis-
lative district in the City of Baltimore and at least one in each of the
election districts of the several counties. The Commissioner of Motor
Vehicles may refuse to register any motor vehicle or trailer which has not
been inspected as required, or which is, in his opinion, unsafe or improp-
erly equipped or otherwise unfit to be operated, and for like reasons he may
revoke any registration already made; provided, however, that the pro-
visions of Section 189 of this Article, with reference to notice, hearing
and appeal shall be applicable in all cases where registration is refused or
revoked under the terms of this section.
