Truck traffic across different U.S. states brings a new set of challenges. Each state has its own laws and logistical quirks that truckers must navigate. States like Texas and California allow larger or heavier trucks than others. This means truckers crossing state lines often need to adjust their loads or obtain special permits. States manage their own toll systems, and some—like Pennsylvania and Illinois—have costly truck-specific tolls. These expenses can influence route planning and profit margins.
