From a driving perspective, our drivers all have to complete a pre-trip of their unit prior to leaving one of our facilities or one of our yards or a rest area where they may have slept for the night. They have to do a complete pre-trip, which includes doing a mechanical check, checking all their paperwork, and updating their electronic device. All of our units have electronic logs. We don't carry the paper log book other than for a backup if there's a technology issue. There's a checklist in the morning or prior to the start of utilizing that vehicle that they have to complete and document. This checklist is subject to audit not only by our company but also by government regulations.
Once they complete that, then they're able to start with their day. We also ask that they stop a minimum of every four hours—
