That had to hurt

YIKES! Damage for two trucks bad enough, near certain injury for driver on left. If banding on the spool broke; thicker materials will spring open just a bit, lighter would unspool, another kind of nightmare.

looks like left truck stopping but no brake lights. would not like to have been one of those drivers. probably should have chains & dogs to restrain, if not possible to lay load flat on side.

Never seen rolls or spools carried on their sides; only the periphery. Material handling equipment partly due, loaded by cranes/ forklifts equipped with a spike, of course standing is how the factories use them. Can't even recall seeing a flat un-coiler; maybe for wire but presses need sheet fed flat.
Who knows what happened to tie-downs. Would have been at least 2 or 3 through the middle tending flat [least effective] 1 each tending forward and to the rear. Some use lever binders, others ratcheting and specified load chain. Is it possible tractor-trailer left a depot unsecured, or just the tie-downs worked loose?

A second look reveals that both trucks look like they are carrying the same load and the left oneshows no restraints like the right. maybe just left warehouse as cant see any clear traffic lanes . Wouldn't like to be in any car/vehicle in place of the right one or any vehicle behind the left one if starting up an incline.
Here, it is the drivers responsibility to check the load: including its weight & bet same where that accident occurred.scarey how an oversight can cause havic/death.

Looks to me like maybe, after tying down the load, the driver failed to pat it with one hand and say: "Yup, that'll hold."

You gotta do that!

Those rolls are not light either. The public is lucky the roll got jammed between the two trucks. Could you imagine what would happen if the roll decided to roll down a busy side walk.

As wizard69 states, definitely NOT light. You might see a truck carry 3 large spools of wire rope, never coiled sheet or wire. Wire rope can only be rolled to a particular minimum diameter, hence the hollow core of wood or metal spool, and I suspect a fraction the length of coil stock. The whole point of coil is shipping greatest quantity possible and that is bound by GVW of semi's and flatbeds.
All that aside, even truckloads of crackers need to be secured.

I appreciate Jon's comment "...driver failed to pat it with one hand and say: "Yup, that'll hold."
"You gotta do that!"

Somewhere in HMT.net a comment noted a video depicted a hand pat on a project indicating completion and satisfaction. They added it's a common Teutonic gesture, rather like affection for an inanimate but 'live' object.

I swear one can find ANYTHING on the web. Curious about the weight of a roll of steel, I Googled and found...

Steel Coil Weight Chart

which says, if I'm reading correctly, that a coil 12" wide and 48" in diameter (close to what I see on the road around here) weighs around 5000 pounds (2.5 tons).

No wonder you never see the trucks carrying more than two. Most of the time I see them with only one, but I have seen them with two, although it's been too long ago to remember dimensions.

On edit...

I used my WEIGHT program to calculate the weight of a steel washer with the following dimensions...

ID = 20 in
OD = 48 in
thickness = 12 in

and it came back with ~18000 in^3 for a weight of 5089 lbs which is in very close agreement with the result obtained from the table. IOW, there isn't much difference between the rolled steel and solid steel which seems intuitively correct.
