Motor Carrier Trip Permits
The State of Oregon sets statutory restrictions on vehicle size, weight and other characteristics. The local road authority has the power to grant variances to these restrictions for roads under their jurisdiction. Typically, a permit is required any time a vehicle exceeds 8 feet 6 inches in width and/or 14 feet in height. Length limits vary between 40 feet and 95 feet depending on the configuration and type of vehicle. Weight limits are also variable and depend on the number of axles and the spacing of those axles.
Single Trip Variance Permit
A Single Trip Variance Permit allows motor carriers to operate above legal size and/or weight limits for a single move on a pre-identified route in a 10-day period. Special requests can be made to allow permits to be active for up to 30 days. These permits are issued by the Oregon Department of Transportation. For trips over county roads, Washington County receives the permit request from the state and adds necessary conditions to the permit. The state compiles information from various jurisdictions into one permit so that the motor carrier does not have to contact several road authorities to obtain approvals. Even if the route uses only county roads, the state is still the issuer of the permit.
Continuous Operation Variance Permit (COVP)
A Continuous Operation Variance Permit, sometimes referred to as an Annual permit, allows motor carriers to operate continuously above legal size and/or weight limits for one year, but below thresholds set by the state and various county jurisdictions. The maximum size and weight limitations not only vary by jurisdiction, but also vary by truck configuration and commodity. These permits do not authorize trips on roads with posted restrictions greater than that authorized by the permit. Pilot car requirements as well as a list restrictions on COVP operation can be found on the County Attachment for the COVP.
Structure Permits and Super Loads
A Structure Permit or Super Load Permit is a special type of single trip variance permit typically for loads wider than 14 feet, higher than 17 feet or longer than 150 feet. Processing time can vary due to the number of inquiries or complexity of the route and dimensions.
If a route request contains both state and county jurisdiction roadways, then the permit will be issued by ODOT. However, if the load is staying on county or city roadways, the applicant must apply directly to the county and/or city.
Motor carriers must submit a description of the route and any potential conflicts with the move and how the conflicts will be addressed. The county will either approve the route or require changes.
Motor carriers must also submit a Temporary Road Closure Permit Application for any lane or road closure and/or a Traffic Signal Shutdown Application required to safely move the load, along with a traffic control plan. A complete list of impacted utilities must be submitted prior to permit approval. The motor carrier is responsible for coordinating the temporary relocation of all utilities. All costs to prepare submittals and relocate utilities will be borne by the motor carrier.

Motor Carrier Reference Map
For more information about restrictions on roads under Washington County jurisdiction, please view the Motor Carrier Reference Map. The restrictions on this map are more stringent than statutorily legal loads. Use this map to plan your route and avoid the restrictions. A special permit may be issued for length- and weight-limited roadways. Permits are not generally issued for weight-restricted bridges.
Unless explicitly stated, no permit will allow the crossing of a bridge above its posted weight limit.
The Motor Carrier Enforcement Program is handled through the Washington County Sheriff's Office. In addition to a full-time weighmaster, equipped with inspection tools and jump scales, there are deputies certified for truck enforcement. Concerns about overweight vehicles crossing posted bridges or other potential violations can be reported to 503-846-ROAD (846-7623), and they will be forwarded to the weighmaster.
