Deggesty Norm, is that in Canada? That is the only place I have seen 12-wheel semi's--I saw two or three on the Prince Rupert-Port Hardy ferry.

No harder than backng a 747 jet into the same spot. Good thing neither is ever required.

I'd like to see it loaded, climbing the hills on I-68 in MD & WV and I am certain those out West are even worse.
Never too old to have a happy childhood!
Closest thing that I've seen to that rig is 2 full-length trailers or 3 pups on the Indiana Toll Road.

I think you're confusing this with platooning. Platooning is not one tractor hauling multiple trailers.. it is several tractor-trailers following each other in close proximity. The lead t/t is driven by a driver while the following units are driverless and"tethered"to the lead vehicle electronically. Once the platoon arrives at its desired general destination it is broken up, and each tractor trailer is then driven to its final destination by a driver. No one is suggesting that truck platoons would be used in tight congested downtown settings or that one tractor would be pulling half a dozen or more trailers. Such long combinations work well in the Australian outback but would be unworkable in North America where we have more rugged terrain as well as more varied weather conditions.
No confusion on my part. It was in answer to bluestreak.

You are confusing what I am seeing - A tractor and 4 trailers coupled to it! No Platooning here!
That's what I'm seeing too.
28 foot pups are being "streched" to 33 ft and will be run as triples on the Toll Road system.

rrnut282[snipped -PDN] I just don't see this being useful anywhere but on long highway only runs, which is in direct competetion with rail intermodal. . . . And as for platooning (gee that sounds familiar, like...like a train) . . . "
And as for platooning (gee that sounds familiar, like...like a train) . . . "
To challenger3980 & others with similar points: It occurs to me that with Chicago being the 'black hole' that it is with regard to most train movements through it (1 -2 day delays, etc.) - and similar though shorter delays for intermodal de-ramping, rubber-tire interchange, and reloading - rail might be more competitive on moves that are entirely on one side of Chicago, but not through it.
As a rail move gets near Chi-town, it starts to suffer from at least multi-hour delays, while a competitive truck on a highway can keep moving. But instead limiting the intermodal run to outside of Chicago avoids that trap, and makes a greater portion of the rail haul more competitive with trucks. In other words, the rails could thereby get rid that 'handicap'.

With no driver, no hours of service violations. No single driver rest delays. Two driver team operations avoid that, but are expensive.
No driver. No delays. No extra labor cost to keep a unit moving. A better return on capital investment that keeps moving and generating revenue. Less time in transit for the customer.
Driverless trucks would have would effect on rail's long haul intermodal market?
Driverless trucks would petty much need dedicated roadways - which could be dedicated to driverless vehicles. The cost of these roadways could easily exceed the savings on labor.
