It is the weight of a vehicle without a cargo
Max allowed weight - tare (empty) weight = permissible payload weight.
The gross weight of a vehicle is the laden (loaded) weight. The Gross Vehicle Weight Rating is the maximum gross weight the vehicle is rated for. The opposite of this would be the tare weight, which is the empty weight of the vehicle.
That depends on what the Gross Vehicle Weight Rating of the vehicle is, and what the vehicle weighs empty (tare weight).
The minimum weight for placarding a vehicle when hauling propane is 1,001 pounds (454 kilograms) of propane. This weight threshold triggers the requirement for placards indicating the transportation of a hazardous material.
The only information provided is that it's a 24' straight truck - that really tells us nothing in relation to the question you're asking. The payload it can haul is the tare weight (empty weight of the vehicle) subtracted from the Gross Vehicle Weight Rating. So, if it's a non-CDL Class 6 vehicle with a Gross Vehicle Weight Rating of 26,000 lbs. and a tare weight of 15,000 lbs., then it can haul 11,000 lbs. of payload. If it's a Class 7 truck (which does require a CDL) with a Gross Vehicle Weight Rating of 33,000 lbs., and a tare weight of 17,000 lbs., then it can haul 16,000 lbs. of payload. But without having the tare weight and Gross Vehicle Weight Rating of the vehicle you had in mind, it's impossible to tell you what you're looking for. Length doesn't determine how much weight it can haul.
Take gross weight or loaded weight and subtract the empty weight to get the tare weight.
Tare weight is the empty weight.
