DRIVER: The driver must have a commercial driver’s license with the appropriate endorsement.
VEHICLE: For a combination which includes a truck tractor and two trailing units, the lead trailing unit (semitrailer) may be up to 40 feet long. The second trailing unit may be up to 35 feet long. However, the primary control is the total cargo–carrying distance which has a maximum length of 68 feet. Any towed vehicles in a combination must be equipped with safety chains or cables to prevent the towbar from dropping to the ground in the event the coupling fails. The chains or cables must have sufficient strength to control the towed vehicle in the event the coupling device fails and must be attached with no more slack than necessary to permit proper turning. However, this requirement does not apply to a fifth–wheel coupling if the upper and lower halves of the fifth wheel must be manually released before they can be separated.
PERMIT: A permit is required for operation if the gross combination weight exceeds 80,000 pounds. A fee is charged. Permitted movements must have the lighter trailing unit placed to the rear, and use splash and spray devices when operating in rainy weather. Movement is not allowed when road surfaces are hazardous due to ice or snow, or when other atmospheric conditions make travel unsafe.
ACCESS: As allowed by the Oregon DOT.
ROUTES: All NN routes.
LEGAL CITATIONS: ORS 810.010, ORS 810.030 through 810.060, and ORS 818.010 through 818.235
Combination: Truck tractor and 3 trailing units—LCV
LENGTH OF THE CARGO–CARRYING UNITS: 96 feet
MAXIMUM ALLOWABLE GROSS WEIGHT: 105,500 pounds
OPERATIONAL CONDITIONS:
WEIGHT, DRIVER, PERMIT, and ACCESS: Same as the OR–TT2 combination.
VEHICLE: Trailing units must be of equal length. The overall length of the combination is limited to 105 feet. Any towed vehicles in a combination must be equipped with safety chains or cables to prevent the towbar from dropping to the ground in the event the coupling fails. The chains or cables must have sufficient strength to control the towed vehicle in the event the coupling device fails and must be attached with no more slack than necessary to permit proper turning. However, this requirement does not apply to a fifth–wheel coupling if the upper and lower halves of the fifth wheel must be manually released before they can be separated.
ROUTES: The following NN routes are also open to truck tractor and three trailing unit combinations.

Combination: Truck–trailer
LENGTH OF CARGO–CARRYING UNITS: 70 feet, 5 inches.
WEIGHT: This combination must operate in compliance with State laws and regulations. Because it is not an LCV, it is not subject to the ISTEA freeze as it applies to maximum weight.
DRIVER, ACCESS, ROUTES, AND LEGAL CITATIONS: Same as OR–TT2 combination.
VEHICLE: The truck or trailer may be up to 40 feet long not to exceed 75 feet overall. The truck may have a built–in hoist to load cargo. Any towed vehicle in a combination must be equipped with safety chains or cables to prevent the towbar from dropping to the ground in the event the coupling fails. The chains or cables must have sufficient strength to control the towed vehicle in the event the coupling device fails and must be attached with no more slack than necessary to permit proper turning. However, this requirement does not apply to a fifth–wheel coupling if the upper and lower halves of the fifth wheel must be manually released before they can be separated.
PERMIT: No overlength permit required.
