We passed this triple in Oregon. Opinions vary as to the safety of having extra long vehicles mixed with passenger cars. Here's a "con"
argument from the literature: "The greater length and weight of long triples makes them incompatible with mixed-vehicle traffic, creating potential hazards for safe passing and merging. In the best of circumstances, the federal TS&W study says, safely passing an long combination vehicle can take 8 percent longer than passing a conventional big rig. Upping the risk factor: Standards for marking passing zones with double-yellow lines on two-lane roads were developed in the 1930s for cars passing cars, not for a car passing a 120-foot long truck combination.
