There should be a sticker on the drivers door somewhere or on the vertical post next to it. Don't just look on the edge of the door by the latch, I had an older C-20 that had the sticker on top of the door edge.
Stands for "Gross Axel Weight Rating"
For a standard five axel tractor trailer, the max is 80,000 lbs
No. It'll have to be registered in accordance with the vehicle's GVWR.
Under the federal bridge law, a tandem is allowed to gross 54,000. According to Chapter 5577.04 of Ohio's law, it would seem to reinforce this, as the maximum allowed weight of any single axle is 20,000 lbs. (provided it has the correct size tyres) and the maximum for a set of tandems is 30,000 lbs. For a tandem dump truck, this is typically 15 to 16 tons of payload, depending on the tare weight of the vehicle.
If you're on a scale which only provides a gross weight, you stop with just the drive axle on the scale and write down that weight. Then you pull forward until your drive axles are on the scale. Write down the total weight of the steer and drive axles... subtract the steer axle weight from the combined weight of the steer and drive axles, and you'll have your weight on your drives. Then you pull forward until all axles are on the scale. That'll be your gross weight. Subtract the combined weight of the drives and steer from that, and you'll have your trailer axle weight.This is basic truck driving stuff.
Without requiring a permit, a standard five axle unit is permitted a gross weight of 80,000 lbs. Typically, this is defined as 12000 on the steer axle, 34000 on the drive axles, and 34000 on tandem trailer axles. You can have a gross of 40000 lbs. on the trailer axles if the trailer has a 10' spread between the axles, and the steer axle can gross up to 20000 lbs, IF the axle and tires are rated for it. However, the max gross weight of the vehicle remains 80,000.
Well, you either go to a CAT scale, which weighs each groups of axles separately, or, if you're on a scale which only shows gross weight, then you axle out. You drive onto the scale and stop with only your steer axle on the scale. Then you write down that weight, and pull forward until your drive and steer axles are both on the scale. Then you write down that weight, and subtract the weight of your steer axle to get the weight on your drive axles. Then you pull forward until all axles are on the scale. This will be your gross weight, and you subtract the weight you got when you had the drive and steer axles on the scale in order to get the weight on your trailer axles.
That would depend on the weight rating of the trailer and bridge law. For a straight truck, five to seven tons.
That depends on the axel trailer.
Varies by states and their bridge laws, as well as the tare weight of the vehicle. Also, you didn't state whether you were referring to commodities loaded by the yard or by the ton. As far as tons go, 15 - 18 tons seems to be the norm, although some states may have higher intrastate weight tolerances.
Yes you can.
Depends. If you have a Gross Combination Weight Rating (that's the combined Gross Vehicle Weight Rating of the truck plus that of the trailer) in excess of 26,000 lbs., with the trailer itself having a GVWR of more than 10,000 lbs. (which a tridem gooseneck will have), then yes. And that's not just Texas - that's a federal law.Now, there are some exceptions to this, in instances where it would not be considered a commercial vehicle. If it's registered as a farm vehicle, is being used for the purposes of that farm, is operated with a 150 mile radius of the farm it's registered to, and is not operated on a third party, for hire basis, and is operated by the farmer, immediate family members of the farmer, or direct employees of the farmer (W2 employees, not 1099 contractors), a CDL is not required.Likewise, if it's a recreational vehicle (e.g., travel trailer), a CDL is not required, so long as it's not being transported on a for-hire basis.
