ORS § 818.010

Current through 2024 Regular Session legislation effective June 6, 2024

Section 818.010 - Maximum allowable weight

This section establishes maximum weight limitations for purposes of ORS 818.020. Except as provided in subsections (4) and (5) of this section or where an exemption under ORS 818.030 specifically provides otherwise, a loaded weight that exceeds the maximum allowable weight as determined by any of the following tables exceeds the maximum weight limitations for purposes of ORS 818.020:

(1) A vehicle exceeds the maximum allowable weight if the loaded weight of an axle or tandem axle is in excess of that determined by the formula in the following table:

______________________________________________________________________________

Table I

The manufacturer's side wall tire rating (but not to exceed 600 pounds) ´ the sum of the tire widths, in inches, of the wheels of the axle or tandem axles = maximum allowable weight.

______________________________________________________________________________

For purposes of the table in this subsection tire width is determined by measuring the cross section of the tread of a wheel, the outer face of a track or the runner of a sled except for the following:

(a) For solid tires made of elastic material, tire width is determined by measuring the cross section between the flanges of the circumference of a wheel at the base of the tire as customarily measured and rated by the manufacturers of motor vehicles and tires.

(b) For pneumatic tires made of elastic material, tire width is the diameter of the cross section of the tire as customarily measured and rated by the manufacturers of motor vehicles and tires.

(2) A vehicle or combination of vehicles exceeds the maximum allowable weight if the loaded weight measured at any of the places designated on the following table exceeds the maximum allowable weight established on the table for measurement at that place:

______________________________________________________________________________

Table II

Place for measurement of weight	Maximum allowable weight in pounds
Any individual wheel	10,000
Any axle	20,000
Any tandem axles	34,000

______________________________________________________________________________

(3) A vehicle, group of axles or combination of vehicles exceeds the maximum allowable weight if the loaded weight is in excess of maximum allowable weight as determined by the method in the following table that produces the lower allowable maximum weight:

______________________________________________________________________________

Table III

(Maximum allowable weight

determined by whichever of the

following methods produces lower weight:)

Method A

The sum of permissible axle, tandem axles or group of axles weights as determined under Table I or II of this section is the maximum allowable weight.

Weights authorized under this subsection are authorized only if the vehicle is transporting field-loaded agricultural products in Malheur County. Weights authorized under this subsection are not authorized for vehicles traveling on Interstate 84 or U.S. Highway 95. A vehicle otherwise described in this subsection that is operating at a weight not listed in this subsection must comply with subsection (1) of this section.

(5) Notwithstanding any other provision of this section, the maximum wheel load for the front axle of the power unit on a vehicle used for curbside solid waste or recycling collection that has tires that are at least 12-1/2 inches wide shall be the load limit established by the tire manufacturer, as molded on at least one sidewall of the tire, up to a maximum of 10,000 pounds, as long as the tire is approved by the Department of Transportation pursuant to ORS 818.012.
