Current through Register Vol. 63, No. 7, July 1, 2024
The following requirements apply to vehicles hauling modular
				building units:
(1) Modular Building
			 Units must be hauled with a truck-tractor or toter and semitrailer or trailer
			 combination.
(2) Equipment weights
			 of the combination and the sizes and ratings of all its components must be
			 comparable to those commonly used by the motor carrier industry in general
			 over-the-road trucking operations.
(3) When operating unladen, the overall
			 length of the combination must not exceed the length authorized by statute or
			 rule, except as authorized in the permit.
(4) Modifications are permitted to the
			 conventional equipment necessary for hauling modular building units. This may
			 include "stretch-trailer" features, adjustable trailer heights from inflatable
			 air bags, steering capabilities for the semitrailer axles or other
			 modifications. These features must be stipulated in the permit.
(5) Requests for moves using trailers more
			 than 53 feet in length will be on an individual basis, and permits will be
			 issued for a single trip only. The authorized trailer length must be stipulated
			 in the permit and must not exceed 75 feet in length, except when using a
			 stretch trailer. When not operating under the terms of a permit issued under
			 this rule a stretch trailer must be reduced to dimensions authorized by statute
			 or rule.
(6) The modular building
			 unit must be securely fastened to the semitrailer or trailer. It may be secured
			 by steel cables and winch tighteners, steel cables or chains and chain binders,
			 or by adequate bolting directly to the semitrailer or trailer frame. Alternate
			 securing methods approved by the United States Department of Transportation
			 regulations may be used.
(7) A
			 single trip permit may be issued for a combination of vehicles that exceeds the
			 maximum allowable weight described in ORS
			 818.010 for a single
			 non-divisible unit when the requirements described in OAR 734-082-0015 (1) and
			 (2)  are met and under the following conditions:
(a) Operations are subject to any posted
			 weight limitation in effect on any highway, highway section, bridge or
			 structure;
(b) The vehicle
			 combination must not exceed the manufacturer's GVWR for the vehicle or the
			 vehicle combination; and
(c) The
			 exception to maximum weight limitations for an idle reduction system 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 provide:
(A) Written
			 certification of the weight of the auxiliary power unit; and
(B) A demonstration or certification that the
			 idle reduction technology is fully functional.
(d) 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.
