Answer:
Regular Operations
The gross weight of vehicles in regular operations (operating without a special permit) is governed by the State's bridge formula (Computed Gross Weight Table in Ala. Code §32-9-20[a][4][c]). State law allows a 10 percent tolerance for weight enforcement (Ala. Code §32-9-20[a][4][d]). See Exhibit 8 for a summary of Alabama weight provisions under regular operations.
