Federal & State Regulations | Oversize and overweight movements - Oregon

General requirements

Reducible expectations	All vehicles and loads that exceed the legal size or weight limitations must obtain a special permit before traveling the highways of Oregon.
Permit timing	The single trip permit will be valid for a period of five working days, for use by the permitted vehicle only (tractor and trailer).
Method of application	Carriers may obtain permits in person, by phone, or by mail at the permit office in Salem, at one of the Port of Entry operations, a number of field offices, or through J. J. Keller & Associates, Inc., Trip Permits, at (800) 231-5266. Permits can also be obtained through Oregon’s Trucking on-line Service.
Payments accepted	Fees may be paid in cash, by check, or permit fee coupon. County administrative fees will be collected where applicable.
Electronic permits	The permit or permit identification card must be in the driver’s immediate possession at all times when driving the vehicle or combination of vehicles upon a public highway, road or street; and display a variance permit or permit identification card upon demand of any police officer, motor carrier enforcement officer, county weighmaster, judicial officer or the director of permits of the Department of Transportation.
Route surveys	Oregon provides several maps that show where certain types of oversize/overweight vehicles may operate. Each applicant for a permit should obtain a set of maps before entering the state.

Insurance requirements

Liability	Verification of public liability and property damage insurance and/or an indemnity bond may be required at the discretion and in the amounts determined by the granting authority. The granting authority may require the applicant to furnish public liability and property damage insurance in a sum fixed by the granting authority and indemnity insurance, or an indemnity bond in a sum fixed by the granting authority.
Coverage	Level III authorization self-issuance variance permits must file general liability insurance having an annual aggregate limit or at least $2,000,000. Evidence of insurance filing must be in the form of a certificate of insurance signed by the carrier's insurer.

Weight Table 3, Heavy Haul Weight-Permit Required (http://tinyurl.com/weighttable3), contains the maximum weight for single-trip permits (based on the number of axles and wheelbase). Other maximums include 600 pounds per inch of tire width; 21,500 pounds per single axle; 43,000 pounds per tandem axle; or the weight shown on the overdimension permit and the sum of the permittable axle, tandem axle, or group axle weight, whichever is less. Weight Table 3 applies to common vehicle types including truck-tractor-lowbed semitrailer, truck-tractor-semitrailers and boosters.

Weight Table 4, Heavy Haul Weight-Permit Required (http://tinyurl.com/weighttable4), contains maximum weight based on number of axles and wheelbase. Table 4 allows for more weight using a shorter wheelbase than that authorized by Table 3. Other maximums include 600 pounds per inch of tire width; 21,500 pounds per single axle; 43,000 pounds per tandem axle; or the weight shown on the overdimension permit and the sum of the permittable axle, tandem axle, or group axle weight, whichever is less. Weight Table 4 applies to common vehicle types including self-propelled cranes, truck-tractor-lowbed semitrailers, truck-tractors with jeep and semitrailer, or truck-tractor with semitrailer and booster.

Weight Table 5, Heavy Haul Weight-Permit Required (http://tinyurl.com/weighttable5), contains maximum weights for specific vehicle configurations only. It provides up to 48,000 pounds per tandem axle if the combination of vehicles has at least nine axles, with a steer axle followed by four consecutive tandem axles which are eight feet wide (standard). Ten percent more weight may be allowed when the combination has 10-foot wide axles with four tires per axle. Instead of 48,000 pounds per tandem, this allows up to 60,000 pounds. Use of Weight Table 5 is more complex than the other weight tables and may require special analysis by the Over-Dimension Permit Unit. Contact ODOT for details.

An online weight analysis tool is available to companies that need to determine the weight of a divisible or non-divisible load and what's allowed under a permit. Visit http://tinyurl.com/weightanalysis to access the online tool.

On overlength moves of 120 feet or more, a rear escort is required on two-lane highways. On moves 140 feet or more front and rear escorts are required on two-lane highways, and a rear escort is required on four-lane highways.

An oversize load must be preceded by a pilot vehicle on two-lane highways when the front overhang is in excess of 15 feet. There are no requirements on Interstate and Multi-lane highways. These overhang escort requirements are in addition to the requirements for overwidth.

Flagperson requirements

Movement of certain oversize loads may require traffic stops or controls to provide for safe passage of the load. Under certain conditions, a pilot car operator, certified in traffic control, may direct traffic.

A pilot vehicle (escort) operator must be certified to direct traffic and the following apply:

A pilot vehicle operator must attend and satisfactorily complete ODOT training related to directing traffic flow;
The training must include procedures that provide a process to close a section of highway for the safe passage of an oversize load;
Successful completion of refresher training is required every three years after initial certification; and
Proof of certification must be carried, and made available upon request by law enforcement, when conducting operations.

When movements require traffic stops or controls by certified pilot vehicle operators, at a minimum, a front and rear pilot vehicle are required. The lead pilot vehicle must be equipped with a sign that reads STOP AHEAD and the sign must be mounted above the roofline of the pilot vehicle, constructed to ODOT specifications for Type Y5 signs, kept clean and legible, and displayed only during operations. The rear pilot vehicle must be equipped to stop oncoming traffic using a handheld STOP/SLOW paddle a minimum of 18 inches across and that has internal lighting or that is faced with prismatic sheeting.

Escort car/Company requirements

Escort/Pilot vehicles may be required to ensure safety during the movement of oversize loads. Pilot vehicles may be a passenger car, pick-up, truck, or truck tractor. Combinations of vehicles are not authorized. Pilot vehicles are to be placed 300 to 500 feet from the oversize load.

Escort car signs, flags, and lights

Warning signs on escort vehicles shall be five feet wide by 10 inches high with eight-inch black letters of a one-inch brush stroke, in accordance with Federal Highway Administration standard alphabet series B, on a highway yellow background. The yellow background must be made of reflectorized material.

Pilot vehicles must have OVERSIZE LOAD warning signs that are 5 feet wide by 10 inches high mounted above the roofline of the vehicle, two flashing amber warning lights, a revolving amber warning light, or an amber strobe light with 360 degree visibility, two-way radio communication with the oversize vehicle, and carry two 18-inch square red flags on three foot staffs, and eight safety flares or reflectors. The warning sign must be visible to the front and rear of the vehicle. Pilot vehicles are under the direct control and supervision of the towing vehicle operator.

If three pilot vehicles are required by permit, and the load will cross the centerline of the highway, additional signs that read REDUCE SPEED and MOVE RIGHT may be required.

It shall be the duty of the pilot vehicle operator to warn approaching or overtaking traffic as the case may be of any hazard caused by the movement, by the use of approved signaling devices or flags and signs. Flares may not be used when escorting hazardous materials. Pilot vehicles shall on rural highways maintain a distance ahead or behind the movement of not less than 300 feet nor more than 500 feet. In cities or in congested areas where traffic is controlled by signals, this distance shall be reduced as may be required to protect the traveling public.
