Of the three components of the ATA Federation, the state trucking associations (STAs) have the longest history. 24 STAs actually predate ATA, some by many years, some by only a few. Today ATA boasts affiliates in all 50 states and each STA is autonomous, providing its own financing, electing its own officers, employing its own staff, and establishing its own policies, bylaws, and dues schedules.” The 50 STAs are divided into four regions according to geography as the map below demonstrates.
