Department of Transportation, Highway Division, Chapter 734

Rule Caption: Maximum allowed tow length for mobile homes

Adm. Order No.: HWD 2-2013

Filed with Sec. of State: 5-16-2013

Certified to be Effective: 5-16-13

Notice Publication Date: 4-1-2013

Rules Amended: 734-075-0010, 734-075-0011

Subject: These rules describe the transportation of mobile homes and modular building units on highways under the authority of the Oregon Department of Transportation. A petition for rulemaking was received from the Oregon Manufactured Housing Association requesting a revision to OAR 734-075-0010 and 734-075-0011 to extend the lengths mobile homes from 75 feet to 80 feet (including the tongue). Nevada, California, Idaho and Washington recently extended permit actions that authorize the movement of mobile homes, not to exceed 80 feet in length. The amended rules follows suit with Oregon’s neighbors to extend the length to 80 feet and will promote administrative efficiency and the efficiency of movement of manufactured building through Oregon and the adjacent states. In addition, the amendments grant the Administrator of MCTD the same authority granted the Chief Engineer with regard to oversight of the movement of oversized loads or vehicles.
