nor more than twenty-five dollars ($25. 00) for the first offense, and to a
penalty of not more than one hundred dollars ($100) for the second or
any subsequent offense, such penalties to be enforced by the Traffic Court
of Baltimore City or any Justice of the Peace of the State having juris-
diction, as provided in Section 204 of this Article; provided, however,
that any person who may feel himself aggrieved by any general regulation
promulgated by the said Board of Motor Vehicle Headlight Inspection
under the powers contained in this provision, may apply to any court of
competent jurisdiction to have the enforcement of the same enjoined on
the ground that such regulation is unreasonable, unlawful or in excess of
the powers herein conferred upon said Board of Motor Vehicle Headlight
Inspection.

Any person who shall turn all or any of his motor vehicle lights off for
the purpose of avoiding arrest shall be deemed guilty of a misdemeanor,
and upon conviction, subject to a penalty of one hundred dollars ($100. 00)
or imprisonment for a period not to exceed ninety days, or both fine and
imprisonment.

(3A) Danger and Caution Signals. Every motor bus and every
motor omnibus for the carriage of passengers for hire, except taxicabs, and
every commercial motor vehicle having a carrying capacity of two tons or
over, shall be equipped with at least two red or yellow burning danger or
caution signals, with friction cap ignition, similar in type to a time-burn-
ing railway fuse signal, and so constructed as to burn with a brilliant red
or yellow light for not less than fifteen minutes.

Whenever any such vehicle becomes disabled while within the limits of
the traveled part of a highway to such an extent that it cannot proceed
under its own power, and its lighting is so disabled that it constitutes a
menace to other vehicular traffic, the operator thereof shall cause to be
continuously displayed on the surface of the highway the red or yellow-
burning danger or caution signals, as herein required, in such manner as
to prevent personal injuries, loss of life, and damage to property by col-
lision.

Any person violating any of the provisions of this Section shall be
deemed guilty of a misdemeanor and upon conviction shall be subject to
a fine of not less than five nor more than fifty dollars, and in default of
payment thereof shall be liable to imprisonment for not less than ten nor
more than thirty days in the discretion of the Justice of the Peace or the
Court hearing such case.

(4) Mufflers. No driver or operator of any motor car, taxicab, auto-
mobile, motor truck or motor cycle shall use any cutout, fitting or other
apparatus or device which will allow the gases from the engine of the motor
vehicle to escape into the atmosphere without first passing through a
silencer, expansion chamber or other contrivance suitable and sufficient for
reducing as far as may be reasonably practicable the noise which would
otherwise be caused by the escape of the said gases; provided that this
regulation shall apply only to a motor vehicle propelled by an internal
combustion engine.
