Current through Register Vol. 63, No. 3, March 1, 2024
(1) The loaded weight of a group of axles,
vehicle, or combination of vehicles shall not exceed that specified in the
Permit Weight Table assigned to the permit. In no case shall the loaded weight
exceed:
(a) 21,500 pounds per axle, except as
described in OAR 734-082-0010(2);
(b) 43,000 pounds per tandem axle;
(c) 98,000 pounds loaded weight for
continuous trip permits;
(d) The
weight otherwise specified on the permit; or
(e) The sum of the permittable axle, tandem
axle, or group axle weight, whichever is less.
(2) Auxiliary axle(s) must be deployed, and
distribute the weight of the load or vehicle, when failure to do so results in
any tire, axle, tandem axle or group of axles exceeding the weight limits
allowed by OAR 734-074-0020.
(3)
(a) In a combination of two vehicles other
than a truck-tractor and semitrailer, the axle and tandem axle weights listed
in subsections (1)(a) and (b) of this rule may be allowed by permit for the
towing vehicle or the towed vehicle, but not both, if the gross weight does not
exceed that authorized in ORS
818.010 except;
(b) When the combination of vehicles is a
motor truck and stinger-steered balance trailer, the axle and tandem axle
weights listed in subsections (1)(a) and (b) of this rule may be allowed by
permit for both vehicles if the load is carried on the balance trailer, and the
towing vehicle is unladen.
(4) Overweight permits will be valid only for
a single non-divisible load, except a permit may be issued for a single load
consisting of multiple assembled parts constituting an integral whole with
detached accessories included in the load, if the accessories are detached to
reduce width, height, length, or a combination of these dimensions, and an
overweight permit could have been issued for the load in its assembled
condition.
(a) Single trip permits may be
issued for combinations of vehicles having a steering axle followed by four or
more consecutive tandem axles, provided the weight does not exceed:
(A) 600 pounds per inch of tire width;
(B) 24,000 pounds per axle, except
as described in OAR 734-082-0010(2);
(C) 48,000 pounds per tandem axle;
(D) The weights listed in Permit Weight Table
5 for groups of axles; or
(E) The
sum of the permittable axle, tandem axle, or group of axle weights, whichever
is less.
(b) Additional
weight for axles or tandem axles may be allowed by permit when the combination
of vehicles described in subsection (a) of this section utilizes axles that are
ten feet wide and have four tires (10 percent additional axle weight), or axles
that are ten feet wide and have eight tires (25 percent additional axle
weight). Any additional weight allowed must be specified on the permit, and
will apply only to axles or tandem axles specifically identified as having the
requisite characteristics. The minimum of the weights listed on Permit Weight
Table 5, calculated by Permit Weight Table 5 formulas, or listed on the permit
determines the maximum allowable weight for groups of axles.
(c) Permits issued under this section are
subject to special routing and analysis by the Department of Transportation.
Weights exceeding those listed on Permit Weight Table 5, or exceeding Permit
Weight Table 5 formulas will require a case by case engineering review and
approval by the Department of Transportation Bridge Section before a permit
will be issued. Permits issued under such Bridge Section review authority shall
specify maximum allowable axle, tandem axle, and group axle weights which may
not be exceeded and shall be valid only for the single specific movement
requested and reviewed unless otherwise expressly authorized by the Bridge
Section.
(d) All movements shall
be subject to any posted weight limitation in effect on any highway, highway
section, bridge, or structure.
(e)
Equipment used in the loading, unloading or operation of the vehicle may be
transported with the permitted item.
(5) The road use assessment fee required in
OAR 734-082-0003 is based on the weight requested for the permit. The weight
shown on the permit is the maximum weight permitted.
(6) The Department of Transportation may
publish tables of weights that may be authorized by these rules, subject to
route analysis for each trip.
(7)
In no instance may the vehicle combination exceed the manufacturer's GVWR for
the vehicle or the vehicle combination and load.
(8) The exception described in ORS
818.030(10) and
818.340(4) is
limited to the actual weight of the idle reduction system, not to exceed 550
pounds. In order to qualify for the exception, the operator of the vehicle may
be required to prove:
(a) By written
certification the weight of the auxiliary power unit; and
(b) By demonstration or certification that
the idle reduction technology is fully functional.
(9) A vehicle that uses natural gas as its
fuel source, or is powered primarily by means of an electric battery, may
exceed the weight limitations established under ORS
818.010 by not more than 2,000
pounds.
Tables referenced are available from the
agency.
