regulate the weights of wagons, trucks, road engines, road rollers, traction
engines, threshing machines or other vehicles of any kind passing over any
bridges or culverts included in the State Roads System and the rate of
speed of such vehicles while passing over the same by posting and main-
taining conspicuously at both ends of or entrance to said bridges or cul-
verts signboards with lettering not less than three inches in height, worded
as follows, to wit: "Warning—Weight not to exceed (here insert numerals)
pounds, Speed not to exceed (here insert numerals) miles per hour, " which
shall be taken to mean that no vehicle of any kind, as above enumerated,
weighing, with or without any load which may be in or upon the same,
more than the number of pounds specified on said signboard, shall pass
or be drawn, driven, propelled or in any other manner taken over said
bridge or culvert, and that no such vehicle of any kind as above enumerated
shall pass or be drawn, driven, propelled or in any other manner taken over
said bridge or culvert at a greater rate of speed than that specified on said
signboard. Any individual, firm, co-partnership, corporation or other
person, whether the owner of such vehicle, the person in charge and con-
trol over the same, or employee or agent of any such who shall draw, drive,
propel or in any other manner take or cause to be taken, drawn, driven or
propelled over any such bridge or culvert posted as aforesaid any wagon,
truck, road engine, road roller, traction engine, threshing machine or other
vehicle of any kind, weighing, with or without any load which may be in or
upon the same, more than the number of pounds specified on the signboard
so erected at the entrances or approaches of such bridge or culvert, or at a
greater rate of speed than that specified on said signboard, without a per-
mit in writing from the State Roads Commission shall be deemed guilty
of a misdemeanor, and upon conviction thereof shall be fined not less than
twenty-five dollars nor more than one hundred dollars, for each such offense;
in addition to which the owner or person in control of such vehicle shall
be liable to the said Commission for all damages which may be done the
same by the violation of the regulation so prescribed. In any trial of any
person charged with a violation of any of the provisions of this section oral
proof of the existence of such signboard posted as herein provided and its
contents shall be accepted as prima facie evidence of the validity of the
regulation thereon prescribed.
