Okla. Stat. tit. 47, § 47-14-109.2: Weighing as single draft

A. Except as hereinafter provided, for the purpose of

delivering agriculture commodities to and from the farm only, any

vehicle or combination of vehicles shall be commercially weighed on

a vehicle scale only as a single draft, that is, the total weight of

the vehicle or combination of vehicles shall not be determined by

adding together the results obtained by separately weighing each end

of the vehicle or combination of vehicles, or by separately weighing

individual elements of such vehicle or combination of vehicles.

Provided, however, that when a vehicle or combination of vehicles is

not weighed as a single draft the weight ticket shall be stamped

"multiple draft weight; not guaranteed accurate". Provided further,

that any one truck and semitrailer or truck-tractor/semitrailer

combination may tow one complete trailer or semitrailer for the

purpose of delivering agriculture commodities to and from the farm,

such single axle and gross weight limits provided for by Section 14-

109 of this title applying fully herein.

B. This section shall not be construed to allow or permit any

vehicle or combination of vehicles to exceed:

1. The axle load limit, as prescribed in Section 14-109 of this

title, of twenty thousand (20,000) pounds per single axle; or

2. The tandem axle weight, as prescribed in Sections 14-101 and

14-109 of this title; or

3. The overall gross vehicle weight of eighty thousand (80,000)

pounds for vehicles or ninety thousand (90,000) pounds for longer

combination vehicles as defined in U.S. Code 23, Section 127,

operating on the Dwight D. Eisenhower System of Interstate and

Defense Highways in accordance with the provisions of Section 14-118

of this title; or

4. The total overall gross weight of ninety thousand (90,000)

pounds for all other highways in this state, except those highways

prescribed in Section 14-113 of this title.
