Will GPS-derived data for mileage be allowed as a substitute for data that cannot be readily obtained from a vehicle electronic control module (ECM)?

No, the ELD must be able to monitor engine operation to automatically capture required data. A GPS is not integrally synchronized with a vehicle’s engine, and cannot be a substitute for required ECM data to comply with the ELD rule.

Did this answer your question? If not, please email ELD@dot.gov or call 1-800-832-5660 for more information.
