OT: modern semi-trucks brakes

[MattiJ]

Seem like brakes on these have improved a lot since dawn of times:

76-ton lumber truck:

90-ton Swedish HCT (High capacity transport) vs sedan:

OK the brakes are GOOD . Now we need to do something about the DRIVERS. :-(

They'll have to start adding better cargo restraints with the better brakes.

Hope that the driver did the cargo securing by himself.
Being lazy or in a hurry sometimes ends up just like that.

From the text and comments you could get the idea that semis keep the safety distance so that they can drive around with unsecured load

Yeah... they need to stop texting so they don't run into a line of traffic at full speed, as has happened two or three times around here.

You've got to be kidding! The only way to totally secure 40'000lbs of i-beams would be to weld them to the trailer! Stop being inconsiderate and give them room. Thank goodness the trucking companies are putting video cameras in the cabs to catch the inconsiderate drivers who cause accidents!

Of importance is the later video. When the truck takes an extra 10 feet to stop the car in front of the truck loses.

I'd be more willing to blame the cars for cutting off trucks and causing accidents if it were not for the thousands of times that I've watched the trucks drafting each other, tailgating autos and cutting cars off so that they can pass the truck in front of them that's doing 64.9 MPH by driving at 65.01 MPH.

Dunno about US but in here the requirement has been for ages that load fastening has to be able to hold 0.8x load weight in braking direction. (0.8G)
Means that you can brake considerably harder than even those videos shown.

Crashes are different matter and its not practical or even possible to tie down the load to be able to survive direct hit to concrete wall but thats totally different case vs load breaking loose when you just hit your brakes.

At least that we have common in here... truckers seem to be perfectly comfortable to drive with 5 meter gap to next car, truck or whatever is in front of you even for 200 miles non-stop.

Now for a real brake test -

Here there are idiots on the road,most of them drive cars and light trucks and they do completely stupid things.Sadly,our legal system has been abused so that stupidity pays well.

Before the advent of dash cameras,the trucking company would have been sued for damages even though the truckdriver wasn't at fault.

I would argue that the brakes on cars are too good.

[wdtom44]

What Danlb says. If a truck takes so long to stop they need to take that into account when they are deciding on following distance, and not fill my rear window and rear view mirror.

Plenty of idiots here too but hardly anyone would risk their lives in an attempt to cash out truck company:
Some years ago truck drifted to opposite lane on a slippery road crashing to a bus full of people, 2000 lbs paper rolls broke loose from restraints and rolled trough the bus indoors flattening everyone on their way.
23 dead, driver got 3 months probation from 23x manslaughter and truck company total 10k$ fines.

X2..... It used to be that the truck drivers were the best and most considerate drivers on the road.

Now, with all the truck driving schools, any crackhead can get a license and be on the road just as if they were a good truck driver. The MBAs at the trucking companies set up nice schedules that cannot be made by following the law. Yes they tailgate. Yes they text while driving. Yes they take 3 or 4 miles to sloooooooowwwwwwwwwly pass another truck going a fractional mph slower. Yes some of them, mostly the independents, drive well over the limit AND do most of the above as well. Relatives on my wife's side drive 18 wheelers and concrete trucks, we hear about rotten car drivers and lousy truck drivers.
