Log truckers have better safety record

And Triple Trailers have a better safety record...

Safest Highway Vehicles
Are triple-trailer trucks safe? It's a commonly asked question about shipment transportation and highway safety. You might be surprised at the answer.
Triple-trailer trucks can operate in 16 U.S. states (Alaska, Arizona, Colorado, Idaho, Indiana Toll Road, Kansas Turnpike, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio Turnpike, Oklahoma, Oregon, South Dakota, and Utah) and in Manitoba, Canadian. In all these locations, triples share a common denominator: they have the best safety record of any vehicle on the highways. This is not the exception, but the rule, according to official state records. For example, after a thorough review of their experience with triples, the Oregon Public Utility Commission announced that triple-trailer trucks were three times safer than other vehicles on the road.
One of the reasons for the excellent safety record of triples is that they are one of the most-regulated vehicles on the road.
According to Colorado State Patrol Lt. Col. William Wolfe, "While some may find them intimidating, these vehicles have an excellent safety record, operating under stricter rules than other trucks. Companies must be preapproved to operate triples, must obtain a special permit, and they cannot be driven on all highways, only those designated by state agencies. They are also prohibited from being driven in extreme weather."
In a study sponsored by the American Automobile Assn. Traffic Safety Foundation, they reached similar conclusions. To quote: "extra-long vehicles (ELV) have a superior safety record. Their accident involvement rates are superior to those of 5-axle semis." The study says "triples are by far the most attractive ELV on the highway."
