              dispatch and everything related to the outside carrier to keep the experience consistent for the Shipper. Dr Dispatch
              has a Broker and a carrier module and can handle dual authority with ease. A broker with many agents will want office

              from letting a facility tie up their trucks as you can’t pick up new loads if you’re stuck somewhere. Detention is meant
              to discourage a shipping or receiving facility from keeping your assets busy and not out earning. This implication is
              the driver is being detained and not the same as blowing a tire and being late – but if you’re charging detention you
              already know that. A lot of large detention lines on rates back during Katrina where sending a truck was important and

              driver’s name and details on each load but in payroll the company itself is paid. Contrast that to a normal company
              driver that you pay via the payroll module – a fleet owner is for sub contracting. If we ask ‘Is the driver part of a
              fleet owner’ we’re asking if it’s a company driver or a driver attached to a fleet company.

              Four –Wheeler – Any vehicle that isn’t a tractor –trailer rig.
              Fuel Surcharge – When fuel prices are higher than normal customers usually pay a surcharge to cover this overage. It’s
              helpful to offer a good per rate with the fuel overages offloaded into this line item to signal to the customer that the
              rate is mostly higher due to fuel prices.
              Fuel Tax – If a truck travels 350 miles across a state, the companies FLEET AVG MPG is used to decide how much fuel was
              burned in that 350 miles, if you do not buy enough fuel in that state you OWE fuel tax, if you bought more than enough
              you get a refund. Use our fuel tax module to report on this. You need miler integration or something to auto break down
              the state miles on a load. Using our fuel import integrations with a miler integration means nearly 100% automated fuel
              tax reporting as the fuel purchases and state miles are figured.

              integrate with online load boards that are actually marketplaces for freight.
              Load number – Older term meaning Progressive Number. In DRD the Pro is the unique numeric ID for your loads (no letters
