2328 ARTICLE 56

ing within space set aside exclusively for parking purposes, in congested
sections, and this provision shall not be deemed as repealed by any Act
hereafter passed unless this provision is expressly referred to and repealed
in terms, or some other clear evidence given of an intent on the part of
the General Assembly to change the policy of the State herein declared;
and provided further that nothing contained in this section shall be taken
to apply to any subsequent or contemporaneous Act of the General Assem-
bly of Maryland itself altering the charges to be made for the registration
or operation of motor vehicles engaged in the business of common carriers,
or placing such a special class for regulation in other respects.

No city, county or other municipal sub-division of the State shall have
the right to make or enforce any local ordinance or regulation, under the
guise of a traffic regulation, to compel the sounding of bells, horns or other
signalling devices.

Nothing in the sub-title shall be taken in any way to add or to detract
from the right of any person injured in his person or property by the negli-
gent operation of a motor vehicle to sue and recover damages as in the case
of the negligent use or operation of other vehicles, and the violation of any
provision of this sub-title shall not be taken to give any right of action to
any individual who would not be entitled to the same in the absence of such
provision.

This section referred to in holding invalid an ordinance of Havre de Grace pro-
hibiting non-residents of that city from operating automobiles for hire; unreasonable
discrimination. Havre de Grace v. Johnson, 143 Md. 605.

There is nothing in statute laws of Maryland relative to motor vehicles inconsistent
with the well settled principle of common law, that a master is not liable for the
unauthorized acts of his servant not committed within the scope of his employ.
Symington v. Sipes, 121 Md. 319.

Acts of 1916, ch. 687 and ch. 610, compared and contrasted; the latter applies to
motor vehicles used as common carriers, including a jitney, although its route may
vary from time to time. Indictment upheld. Class "F" of sec. 157 has no application
to a jitney. The fact that ch. 610 applies to jitneys does not make it applicable to
taxicabs. Power reposed in public service commission under ch. 610. Smith v. State,
130 Md. 484. And see Goldsworthy v. Public Service Commission, 141 Md. 682.

The term "common carrier" includes motor vehicle transportation companies—art. 23,
sec. 345.

of automobiles, see art. 27, secs. 396, and 397.

This section cited in holding invalid portion of ordinance of Baltimore City giving
right of way to vehicles of physicians, without providing means of identifying such
vehicles. Kidd v. Chissell, 146 Md. 172.

146. Except to the extent that they may be specifically authorized by
other provisions of this sub-title, no city, county or other political sub-
division of this State shall have the right to make or enforce any ordinance
or regulation upon any subject for which provision is made in this sub-title.

er identical therewith, or similar or equivalent thereto, are hereby re-
pealed; and the charters of all municipal corporations of this State are
