In my state the regulation uses the most common measurement of 41 feet and
measures the distance from the trailer kingpin to the middle of the set of
trailer tandems. This limit applies to any trailer more than 48 feet in
total length and it applies to empty and loaded trailers.
There is a widespread misconception that empty trailers can be on the road
with tandems to the rear, they cannot. The regulation doesn't mention
anything about trailer weight only the total length of the trailer. If your
trailer is more than 48 feet, in my state, you must make your tandems legal
even if it is empty.
On some of our 53 foot trailers the "41 foot" mark is in the wrong place
because it's not a 41 foot mark it is a customer mark. The mark on some of
oo\ur trailers indicates where the tandems must be to accept the maximum
load from a customer. Our state doesn't require a 41 foot mark on the side
of the trailer.
To make sure the tandems are not over length I also compare the rear mudflap
of the tandem to the point where the trailer door is pinned in the open
position. The mudflap needs to be about a foot or more in front of the edge
of the trailer door when it is held in the hold-open or backed-into-the
loading-dock position.
States measure compliance in different ways and they have different maximum
lengths. Some states measure from kingpin to hub of front or rear tandem.
Some states use 41 feet and some use less. Check your atlas ad avoid a
ticket. You can get a ticket from a trooper on the road or any other
officer with the proper training. You aren't at risk only at the scale
house. In my state the fine for overlength is $150 or more.

California was notorious for enforcing kingpin to rear axle laws even on
interstates. I think they must have been sued a few times for that because
now they don't seem to give a shit. I've seen 53ft trailers with the wheels
slid to the rear and nobody said a word. Then, how ya gonna adjust the
wheels of a 53ft car hauler?
Pointing out that king pin to rear axle laws can only be enforced on state
roads. Not interstates and the designated truck route system.
Someone drops in here and finds this they might think this is a
trucking-related group.

That depends on the freight and how it's loaded. Practically anything under
40k won't have an effect to any degree. Loads over 40k are generally loaded
as if the trailer was a 48ft. So you'd have 5 feet of open space in the
rear.
Not always, it depends on the weight of the load, total gross weight, how
the freight is loaded in the trailer, etc. On refrigerated trailers it is
common to put a single pallet in the front of the trailer to counter balance
the weight of the refigeration unit. I've had loads of 18 pallets that
maxed me out weight wise, so loading them require multiple single pallets.
Sliding trailer tandems fully to the rear won't necessarily put you
over-axle on the drives if the load in the trailer is light enough. Our
problem at work usually involves trailers that are empty or lightly loaded
with the racks that hold the auto parts that were shipped from supplier to
factory.

One of the few tickets I've gotten was for kingpin length, on SR 27 in
Florida. The tandems wouldn't slide, and I was on my way to the terminal. I
probably could have been more persistent, and fixed it.
Lesson learned (for $100).

That's a very, very general statement.
One of the joys of pulling tankers......if I can gross it I can axle
it. On a rare occasion though you can find a nitwick at a scale that
doesn't understand non-compartmentalized or non- baffled tankers &
they get their undies in a bunch when your 20K over on your drives &
then you go 20k under a few seconds later. More often they'll just sit
you on the scale till it settles down.
"block Rocky" but continue to post about him? And not only did
JerryD(troll) post about me but I was the first thing he posted about.
My 3 post from this month obviously weren't blocked very well because
JerryD(troll) still had to say something. "hehe" - JerryD(troll) two days
ago.
BTW Jeff/Zeke, I'm surprised you didn't catch how much JerryD(troll) still
thinks about me.

I've found the opposite is true. Most of the time they wave me thru
because they don't want to wait for the load to settle. As long as It
looks like it's within gross.
That's quite true.......most of the time. I have run across some (KS)
that have created a backup on the scale ramp waiting for my load to
quit moving. Where I'm running now there aren't many scales & the
ones we cross don't bother us. Where I load its usually around 79500
gross & never over 80K. A trick I found years ago to stop a load from
moving is to take the brakes off & let the truck roll back & forth
under the load, takes about half the time to stop it from moving
Where you find the laws most numerous,
there you will find also the greatest injustice.
Arcesilaus
Yes that is true and all you have to do to learn that is use on a scale that
lets you see your own weight because the display will show you how much
quicker your weight will stop fluctuating if you don't hold your brakes on.
Rocky
Hey, that's a pretty good idea. So you roll up on the scale into position,
come to a full if gentle stop and then release the brake pedal? When do you
release the brakes, as the load sloshes forward or back?
Do shippers load by weight or volume?
"Forward or backward" doesn't matter because whatever way it the load is
moving it will be moving the opposite direction in a few seconds.
If you look at your drive tires while you are on the scale, without your
brakes you can even see them move a bit and then move the other way a little
bit.
Rocky
It weird what happens when you release the brakes as you sit on the
scale. The load will quit sloshing & the truck will actually start
mimicking the slosh effect. It will roll forward & backwards a few(or
sometimes several) times basically expending the loads kinetic energy.
when it rolls forward off the scale you wait till it stops then gently
roll it back on.....ditto for when it rolls back. I think what its
doing is using its energy to roll unlimited rather than bouncing off
the ends of a relatively short trailer creating the slosh effect.
>
>Do shippers load by weight or volume?
Both. The stuff I'm hauling now(asphalt) is loaded by volume based on
weight. Its pretty accurate. They just take the net allowable weight &
determine how many gallons product to load. Generally I'm grossing
around 79500. The stuff I'm hauling now has virtually no slosh at all.
Kinda nice.
That really makes sense about how and why releasing the brakes dampens the
slosh, is that the term tanker drivers use? Architects use the same apprach
to reduce earthquake energy in some high-rise buildings. They put a large
mass in the top of the building and in case of earthquake that mass begins
to oscillate out of phase with the building's movement to reduce the sway of
the building.

Unless it keeps going in that direction...
