From a broker’s perspective I would tell you, or anyone for that matter to stay away from box trucks and sprinter vans. They make somewhere between 30-70% of what dry vans make, and it’s often harder to find loads for those types of carriers due to weight and dimensional restrictions. Start with dry vans, they are the easiest to manage by far. When talking to a broker, you want to know the commodity, weight, pallet count, and if it even SOUNDS like it might be hazmat, you better make sure you ask them about it. If it IS hazmat, make sure your driver has a hazmat endorsement and the correct placards. Bear in mind, that a carrier can haul UP TO 1001lbs of hazmat WITHOUT a hazmat endorsement. Let me explain where this might apply; let’s say you see a load posted for Walmart from one of their DCs to a store. That load may contain a pallet containing 300lbs of batteries, 400lbs of antifreeze, 200lbs of paint thinner, and 100lbs of bleach. The rest of the load may be any combination of furniture, clothing, household goods, etc… This ensures that they don’t have to have their drivers, or any driver they broker a load out to, to have a hazmat endorsement which would be much more costly. Brokering hazmat loads, from experience, costs up to 2.5 times as much as a non-hazmat load simply due to the risks and legal liability involved on the carrier’s part for hauling that kind of load. So, this exception allows for small amounts of hazmat to be carried since it poses very little risk to human health or the environment if a serious accident occurs.
