Iowa DOT News Release

Electronic logs regulations for commercial vehicles take effect Wednesday

Posted on: December 17, 2019

ANKENY, Iowa- Dec. 17, 2019 – Effective Wednesday, Dec. 18, 2019,  commercial vehicle drivers that are required to log their hours of service will no longer be allowed to utilize automatic onboard recording devices or paper logbooks per the guidance of the Federal Motor Carrier Safety Administration. All commercial vehicles are now required to have electronic logging devices (ELD) to track the hours of service.

The Federal Motor Carrier Safety Administration implemented the ELD rule to make it easier and faster to accurately track, manage and share the record of duty status information, and to help improve road safety and reduce the number of crashes. An ELD automatically records a driver’s driving time and other hours-of-service data. Hours-of-service rules and regulations were developed to minimize driver fatigue and improve safety for everyone on the road. In addition, ELDs monitor a vehicle’s engine data, such as when the engine is running, whether the vehicle is moving, miles driven, duration of engine operation, etc.

This new rule does not change any of the underlying hours of service regulations. It is simply a more secure way to track those hours.

A commercial motor vehicle driver who does not comply with the new rules as of Wednesday risks being taken off the road for a period of time until the regulation is met. 

For more information regarding ELDs, the ELD final rule, hours-of-service, etc., visit FMCSA’s website.
