AOBRD use of algorithm

§395.15 Automatic on-board recording devices.   

Guidance Q&A

Question 3: May an automatic on-board recording device use an algorithm to identify the location of each change in duty status relative to the nearest city, town, or village?

Guidance: Yes, provided that the accuracy of the algorithm is sufficient to ensure correlation between the driving time and distance data provided through the on-board recorder’s integral connection to the vehicle’s systems. Furthermore, the description of the location must be of sufficient precision to enable enforcement personnel to quickly determine the geographic location on a standard map or road atlas.
