DOE Diesel Price Band — How Southeastern's Surcharge Is Set

Southeastern Freight Lines publishes a schedule mapping ranges of the weekly DOE/EIA national average on-highway diesel price to a fuel surcharge percentage. When the EIA publishes a new diesel price (every Tuesday), the surcharge moves to the band containing that price.

The trigger variable is public: see the current diesel prices by state or pull the weekly index from the Diesel Price API.
