Warning lights for power units when the width exceeds 8 feet 6 inches:

 In addition to any other lights required by law, an overwidth motor vehicle or a vehicle transporting an overwidth load shall be

equipped with amber warning lights when the width exceeds 10 feet on a 2-lane or 12 feet on a multi lane highway.

 These lights shall be mounted above the roof of the cab, be clearly visible from a distance of 500 feet, have a minimum of 30 flashes

per minute and be either:

(A) Two flashing amber lights as widely spaced laterally as is practical;

(B) Revolving type amber light(s); or

 An overwidth vehicle or a vehicle transporting an overwidth load is exempt from the warning light requirements when operating with a

minimum of two pilot vehicles on all highways.

Red/Fluorescent Orange flags and lights to mark extremities:

 Overwidth loads must be marked at the outermost extremities during daylight hours with red/fluorescent orange flags not less than

18 inches square, visible to the front and rear. The attachment device shall not extend beyond the widest extremity by more than 3

inches on either side. During the hours of darkness the outermost extremities must be illuminated by lamps or markers as described

by the requirements of ORS Chapter 816.

 Loads extending beyond the rear of the load-carrying part of the vehicle 4 feet or more, shall be visibly marked with a

red/fluorescent orange flag not less than 18 inches square attached to the outermost extremity of the load during daylight hours. The

attachment device shall not extend beyond the rear of the load more than 3 inches. End load lights described in ORS 816.290 are

required when visibility is less than 500 feet due to darkness, snow, mist, rain, dust, smoke, fog or other atmospheric conditions when a

load extends beyond the rear of the load carrying part of the vehicle 4 feet or more.

Loads transported on drop deck trailers: When a load more than 40 feet in length extends more than 5 feet beyond the rear of the

semitrailer, the load must be non-divisible in length and the length of the load must be specified on the permit. The load may be

transported on the lower deck of a drop deck semitrailer and may extend beyond the rear of the trailer up to the length authorized by the

permit. In addition to the load transported on the lower deck of a drop deck trailer, a load may be transported on the upper deck of the

trailer providing the load does not exceed 14 feet in height or the height authorized by the permit. When an over-dimension permit

authorizes a height exceeding 14 feet, the load on the upper deck may not exceed the height of the load on the lower deck, and must be

non-divisible in height. When a divisible load is transported on the upper deck and the lower deck of a drop deck trailer, the weight shall

not exceed Permit Weight Table 1 or 2 as authorized by the permit.

Weights authorized by permit are subject to all the following limits:

 Tires may carry up to 600 pounds per inch of tire width or the manufactured sidewall rating, whichever is less.

 Permits issued for divisible loads or non divisible load authorizing Permit Weight Tables 1 or 2 allow up to a maximum of 20,000

pounds on a single axle and 34,000 pounds on a tandem axle; and authorizes Exceptions 1 and 2 shown on Permit Weight Table 1.

 Permits issued for a non-divisible load authorizing Permit Weight Tables 3 and 4 allow up to a maximum of 21,500 pounds per single

axle and up to 43,000 pounds per tandem axle. Permits issued for a non-divisible load authorizing Permit Weight Table 5 allow up to a

maximum of 24,000 lbs. per single axle, 48,000 lbs. per tandem axle when the combination consists of a steering axle and four or

more consecutive tandem axles. When additional axle weights are authorized by permit, axle weights must be specified on the permit.

 Permits issued for non-divisible self-propelled or towed fixed load vehicles equipped with low pressure flotation tires at least 15 inches

wide are authorized up to 700 pounds per inch of tire width up to a maximum of 36,000 pounds on a single axle and 43,000 pounds on

a tandem axle.

 All groups of axle weights shall not exceed the sums of the permittable axle weights or the weights allowed by the Permit Weight

Table whichever is the lesser of the two. When the permit authorizes a Permit Weight Table Formula, the formula shall take

precedence over the weight specified on a permit weight table.

 Combined gross weight shall not exceed that specified on the permit.

 Auxiliary axle(s) must be deployed, and distribute the weight of the load or vehicle, when failure to do so results in any tire, axle,

tandem axle or group of axles exceeding the weight limits allowed by OAR 734-074-0020.

When transporting a single non-divisible load and the combined gross weight of the vehicle/load exceeds 98,000 pounds, a Single Trip

Permit must be obtained and Road Use Assessment Fees paid in lieu of weight-mile taxes.

“Heavy Haul” is a term used to denote weight(s) for non-divisible loads that exceed those authorized by Permit Weight Table 1 and

Permit Weight Table 2.

Specifically identified locations may require additional precautions. Permits may specify locations that require certified flagging to be

conducted. The flagging shall be conducted in accordance with the standards in the Manual on Uniform Traffic Control Devices as

adopted in OAR 734-020-0005. In accordance with OAR 734-070-0060, Pilot Vehicle operators certified in traffic control may direct

traffic when the variance permit authorizes a rolling stop option in lieu of certified flagging. The rolling stop method shall be conducted

with three pilot vehicles that are certified and trained to perform the rolling stop method.

Pilot vehicles may be required to ensure safety during the movement of oversize loads. A pilot vehicle may not tow another vehicle. The

pilot vehicle(s) shall be positioned at a distance of 300 feet to 500 feet from the oversize vehicle/load. In areas where traffic congestion is
