    Non-Divisible Bonus Weight

    Additional weight for tandem axles may be allowed, by permit, when the combination of vehicles is equipped with a steer axle followed by four or more consecutive tandem axles. Permit Weight Table 5 may allow up to 48,000 pounds per tandem if qualified.

Additional weight may also be allowed for certain 10 foot wide axles if the combination has the requisite four consecutive tandem axles. These weights must be hand calculated and more information may be obtained by calling 503-373-0000 and speaking to one of our permit analysts.

For calculating bonus weights for non-divisible loads make sure the proper selection has been made on the Entry screen. Only vehicles with four or more consecutive tandem axles qualify for bonus weight.
