Triple deck road trailers are a major hazard on our roads in windy
weather. *

You mean double deck...

I mean triple deck. The Wilson Tridecker for one, unless the
authorities have seen sense and banned them. The third deck is
obtained by underslinging like a low loader. Thus the lowest floor
nearly touches the road, the roof is 15' 9" above ground and a side
wind has nowhere to escape.

And actually they aren't. I can't recall ever seeing one on its side. I
also drove the very first reefer ones that came to the UK and they were
no worse in high winds than a normal trailer.

Quite a number of tri-deckers have gone over. One I particularly
remember went over on the M6 a good few years ago wiping out a family
of eleven in one hit.

Maximum height of a vehicle in the UK is 15ft 9in. Above that it's an
abnormal load. Take off the height of two adults standing up and that
leaves you under 4ft to create a third deck, have the
wheels/chassis/drivetrain etc.

Practically a height of about 15' 9" is correct although there is no
"legal" height limit in the UK.

Theoretically you could try the old lowbridge double deck bus idea of
a side corridor generating height under the seats of the upper deck.
Put one corridor on one side and the second on the other, then try to
load/unload in the rush hour and stay popular!

Shame it's wrong. Having actually driven a 15ft 9in high trailer
quite a lot, it is no worse than a normal height one.

What sort of things are trailers that high used for?

Double decker pallets/cages.

Wrong.

Stagecoach tend to use DD buses for
rural routes.

Not in Hampshire.

IIRC Stagecoach (and other operators) were given huge subsidies to
update their fleet within London. The buses that were replaced were
then moved all over the country to replace the ageing stock left over
from Stagecoach's various acquisitions. They even shipped some of them
out of the country to bolster the fleets of some of their other
operations.

Hence the ex-London double-deckers cropping up all over the country.

Er yes they do, I was on one this morning between Bishops Waltham and
Swanmore. Stagecoach 69...

What tosh. Stop making things up, it does your position no good whatsoever.

I _think_ I've seen photos of a tour bus used for exotic holidays in
China or Central Asia which had minimalist sleeping quarters onboard,
arranged in such as way as to sort-of have three decks. It also pulled a
trailer, IIRC.

Now quite the same thing, but there are trains on the Continent with
seats on three levels (downstairs, upstairs, and a middle level at the
ends over the wheels), and I suppose a bus could be arranged in a
similar manner if someone thought of a reason to bother.

Good point , hadn't thought of that.

Shame it's wrong. Having actually driven a 15ft 9in high trailer quite
a lot, it is no worse than a normal height one.

Maybe, but a DD bus in high sidewinds, at motorway speed, is hairy.
Short(ish) wheelbase compared with a truck.... 33ft long bus, front axle
centred around 5 ft from front, rear axle around 6 ft from rear, gives a 22
ft wheelbase on two axles. Twitchy.

An artic rig will have

a) more axles (so rather more weight low down) and

b) they will be distributed over a greater length of the vehicle (which
must contribute to directional stability) and

c) the load distribution of a truck is different. In a bus, half loaded,
then that half load will usually go and sit upstairs.... leaving the bottom
deck empty save for a few grannies....
