NOTES: Truck crossings do not represent the number of unique vehicles and include both loaded and unloaded trucks. Crossings do not include privately owned pickup trucks. The data for incoming trucks exceeds the data for truck containers loaded and unloaded (empty) because some incoming trucks do not carry a container. The states listed in the table comprise all states with truck entries at U.S.–Mexico border.
