meeting a state highway maintained by the state for a distance not
exceeding one hundred feet from such state highway maintained by the
state, may by order, rule or regulation:

1. Designate through highways and order stop signs, flashing signals
or yield signs erected at specified entrances thereto or designate any
intersection as a stop intersection or a yield intersection and order
like signs or signals at one or more entrances to such intersection.

traffic.

9. Exclude trucks, commercial vehicles, tractors, tractor-trailer

vehicles.

11. Determine those highways or portions of highways which shall be

weight, designated length, designated height, or eight feet in width,
from highways or set limits on hours of operation of such vehicles on
particular state highways or segments of such highways. Such exclusion
shall not be construed to prevent the delivery or pickup of merchandise
or other property along the highways from which such vehicles or
combinations are otherwise excluded.

23. Authorize the use of shoulders or slopes of any state
controlled-access highway by motor vehicles.

(b) The department of transportation shall cause to be determined, for
all bridges and elevated structures under its jurisdiction, the capacity
in tons of two thousand pounds which the bridge or structures will
safely carry. At bridges or structures of insufficient strength to carry
safely the legal loads permissible by section three hundred eighty-five
of this chapter, the department of transportation shall cause signs to
be erected to inform persons of the safe capacity.

(c) Such department of transportation shall cause signs to be erected
to inform persons of the legal overhead clearance for all bridges and
elevated structures on highways under its jurisdiction. The legal
clearance shall be one foot less than the measured clearance. The
measured clearance shall be the minimum height to the bridge or
structure measured vertically from the traveled portion of the roadway.
On bridges or structures having fourteen feet or more of measured
clearance, no such signs shall be required.

weight on any wheel, axle, any number of axles, or per inch width of
tire when in its opinion such highway would be materially injured by the
operation of any such vehicle thereon. Such exclusion shall take effect
upon the erection of signs on the section of highway from which vehicles
are excluded, and a notice that such vehicles are excluded shall be
published in a newspaper in the county where the highway is situated.
The exclusion shall remain in effect until the removal of the signs is
directed by the department of transportation.
