Section 734-074-0020 - Maximum Allowable Weights

(1) Except as described in (10), the maximum allowable weights for single axles and tandem axles must not exceed those specified under ORS 818.010(1) and (2).

(2) Except as described in (10), when the loaded weight of a group of axles, vehicle, or combination of vehicles is 80,000 pounds or less, the maximum allowable weight must not exceed those specified under ORS 818.010(3).

(3) Except as described in (10), when a group of axles or gross weight is more than 80,000 pounds, the maximum allowable weights must not exceed those set forth in Permit Weight Table 2, revised January 2019. This form is available from the CCD Over-Dimension Permit Unit, and by reference is made a part of these rules. In no case may gross weight exceed the sum of the permittable axle, tandem axle or group of axle weights, whichever is less.

(4) In no case may any rim or wheel carry more weight than that specified by the manufacturer of the rim or wheel.

(5) All single axles of triple trailer combinations must have either four tires or two new generation wide base single tires, except for the power unit steering axle and lift axles that may have two tires. Tires on each axle must be of the same size and construction unless the vehicle encounters a tire problem and is in route for tire servicing. Use of new generation wide base single tires is allowed provided that the legal weight of the vehicle, axle or tire load rating is not exceeded.

(6) For purposes of Division 74 rules, the axle(s) of a converter dolly or dolly are not included in determining authorized weight unless those axles carry part of the weight of the cargo being transported.

(7) In any triple trailer combination, the first two cargo carrying units, including the power unit, may not weigh more than 80,000 pounds unless equipped with tandem drive axles.

(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.

(10) The vehicle combination described in OAR 734-074-0010 (1)(h) may not exceed the following weights:

(a) The axle and group axle weights shown on Weight Table 4, revised January 2018.

(b) A gross weight of 129,000 pounds.

(c) When the gross weight exceeds 98,000 pounds, Road Use Assessment Fees as described in ORS 818.225 must be paid.
