NOTES: Data represent the number of truck crossings, not the number of unique vehicles, and include both loaded and unloaded trucks. Does not include privately owned pickup trucks.
The data for incoming trucks may not be equal to the data for truck containers loaded and unloaded (empty) because some incoming trucks do not carry a container.
