No. Carriers negotiate rates based on the entire bid of service. When this rate is negotiated, availability of owner operator trucks is not a factor as when the bids are presented, the day of the week is not present in bid information. Company trucks carry the majority of this freight, and all rates are negotiated with the assumption that trucks are equally available for any load. If a day of the week adjustment is required by the way the customer does business, then this is up to them to adjust, as every company is different, and no specific day of the week adjustment can be made for everyone.
