The use of electronic on-board recorders (EOBRs) has grown significantly in the past few years. They have proven to be very effective tools for hours of service (HOS) compliance management. Carriers using EOBRs have realized superior ratings for HOS compliance in the Compliance Safety Accountability (CSA) program’s safety measure system. There are, however, some naysayers and skeptics that based on misperceptions have argued against the use of EOBRs. The actual experience of the industry, though, suggests that these are just “EOBR myths” and looking at EOBR related facts and industry’s experience (outlined below) clearly demonstrate the usefulness of these systems.
