The electronic logging device mandate, effective on Dec. 18, 2017, requires most carriers and drivers to convert from using paper logs or logging software to a registered ELD if they do not have an automatic on-board recording device in use. And those using AOBRDs prior to the mandate’s effective date will only be able to keep using them for two more years (until Dec. 16, 2019).

It’s a mandate that has led to a lot of questions, with the government continuing to clarify and tweak the regulation even as we went to press. We’ve endeavored to find answers to the most common questions that arise, starting with the basics.
