Ask the right question; all carriers have straps, chains, binders and tarps, but do they know how to properly secure your load. Not all carries specialize in freight all kind.
Example – If you need to move a load of pipe; make sure the carrier has pipe stakes, dunnage, chalks, chains or binders (drill pipe need chains – coated pipe need straps).
Example – If you need to move a specialized load; carrier should have knowledge on routing, permit requirements and trailer required (i.e. loads over 10′ high require double drop or RGN trailers, single piece (not reducable) that weighs more that 48,000 lbs needs additional axles)
