    PrePass sends out:
    DOT Number
    Company name
    Truck type
    Truck vin
    Truck license

    The DOT number activates the companies safe stats and if the company has a bad score and needs to be brought in for an inspection from L1 to L-3

    Weight and wheel spacing lenght is transmitted by the rollover scales in the ground which also active the red light if there is a problem

    If you see cameras around the arm over the road, a picture of several things will be on the TV monitors for the officer to view such as;
    Tag
    DOT Numbers
    Driver
    What the truck looks like
    and some even have, in the lanes into the scale a heat sensor looking at the brakes and which ones are hotter than others or actually cooler ( meaning way out of adjustment!) and a speed sensor in both the road by the sensor and in the lanes into the scale.

    I don't know why I'm going to put this in here but they also can tell your following distance.
    For you MORONS who are so scared when you cross a scale and can't figure out that the SPEED LIMIT sign means that 35 means 35 and not 20 you are screwing up everyone behind you as they see 35 and are trying to maintain that but your scared arses panic! You need to go back to BK! Just do the speed limit and you just might go through with no problem but please quit with the going less than the posted through the scales as everyone gets stacked up behind you and they get flagged in because they got to close to the truck in front of them! How hard is it to do a 35 or whatever speed limit in a scale house! Ky is about the only state that requires you to do 10 MPH! those scales need to be upgraded!

    There was talk that companies might be able to send in the shippers information on the load to aid in tracking by LEO in case it was a highly sensitive type of load but IDK what became of that. I think the companies whined enough about it costing them more in operational costs to have someone having to call in or post all their trucks and it might have been dropped due to that!

    But the most important information sent in by the unit is the DOT number so that the company stats will be run and if they have a 'bad" score they will be brought in for a closer look. Hence the reason to keep that log book up to date until EBOR goes into full effect! It's also a good reason every driver out there KNOW the company or BFI POS you drive for and look at the safe stat scores on a monthly basics so you'll know that your head could be on a block when you pull up to a scale and to have all those ducks in a row marching to the same band!

    There is also a little know fact that DOT does a random audit/survey of trucks.

    Ok, you know you have a good Safe Stat score but you get a red light.

    What the officer does is they set a counter on the computer and they might pull in ever 5th 6th 7th or whatever number headquarters tells them to just to do a random weight check, tire check or visual as it pulls across the scale and to even look at the driver and even the dash board! I went in for a random L-1 and I asked the office what he looks at and what sparks his interest and he said the first thing that makes him want to do any inspection is the dashboard of the truck.

    If there is paper on it or a lot of stuff/junk he figures if the dash is that trashy the rest of the truck and log book is too and he's usually right on a, he said, 93% rate!

    Makes you think about cleaning that dash off!

    The VIN is the one thing that can't or is really hard to fake! It's stamped into the plate in the door whereas that tag can be stolen, the DOT number faked and printed on the side of the truck and even the IFTA stickers can be printed and faked and glued to the truck! The vin when sent over the computer and in the officers hand while inspecting the truck always looks at that number. Even opening the door gives them a look at the inside of the truck! Ever wonder why it's not in the dash like your car and P/U truck? Well is is a PITA to climb up there to look!
    An awful lot of information can be sent in a second. But the most important one it sends which I forgot to mention was the boxes ID Number! The rest I got from our permits guy when I asked him.
    Oh wait for the bttery to go dead! That'll make your week or two till you can get it replaced! LOL! Ain't nothing like pushing that test button and getting nothing! And all the scales in the world are open!

    Aren't they also screwing themselves? If the W-I-M is set to 35 and you roll over at 20, wouldn't that flag you to hit the scale, too?

    Following distance can help, too. Stay far enough behind from the truck ahead of you and hopefully you can maintain 35 long enough to roll over the W-I-M
