WEIGHT, CONSTRUCTION AND EQUIPMENT OF
MOTOR VEHICLES.

The maximum rate of speed for motor vehicles, equipped
wholly or in part with solid tires, weighing six tons or less,
shall be twenty-five miles per hour. The maximum rate of
speed for motor vehicles, equipped wholly or in part with
solid tires, weighing in excess of six tons, shall be twenty
miles per hour. The weight of such motor vehicles shall
be computed by adding the weight of the vehicle and the
weight of its load. Whenever a trailer is attached to such
vehicle, the weight thereof shall be computed by adding the
combined weights of such vehicle and such trailer and the
combined weights of the loads thereon; provided, however,
that when the trailer is equipped with adequate brakes,
the weight shall be computed by adding the weight
of the vehicle and its load, or the weight of the
trailer and its load, whichever is the heavier; and provided
further that not more than one trailer shall be attached
to a motor vehicle while operating along any highway of
this State at a greater rate of speed than ten miles per
hour. The maximum rate of speed of all traction or other
iron tired engines, and motor vehicles or trailers equipped
wholly or in part with iron tires shall be six miles an hour.
No motor vehicle in excess of ninety-six inches in width,
including the load thereon, except traction engines, shall
be operated on any such highway in this State, and no trac-
tion engine in excess of one hundred inches in width shall be
operated on any such highway, nor shall any motor vehicle
equipped with solid tires be so operated of which the total
weight of vehicle and load per inch in width of each tire
as such tires are rated by the tire manufacturers shall ex-
ceed six hundred and fifty pounds, without the special per-
mission of the State Roads Commission in the case of a
road under its jurisdiction, or the permission of the city
authorities in the case of a city street, or the permission
of the county authorities in the case of a county highway,
nor shall any such vehicle be operated at any time on any
such tires when the rubber thereon is less than one inch
