The 2017 Truckload Carriers Association (TCA) set up shop in Nashville, TN, and the exhibit hall at the groups's yearly gathering showcased a bevy of offerings for fleets, ones largely oriented towards technology: electronic logging devices (ELDs), transportation management systems (TMS), freight costing programs, and the like. Here are a few of the initial sights seen at the TCA's annual convention. (All photos by Sean Kilcarr for Fleet Owner)
