Electronic Logging Devices

Hours of Service (HOS) logs are an important component of safe trucking. Using these logs helps ensure that drivers get enough rest between work shifts, preventing driver fatigue. Unfortunately, paper logs are not always accurate.

In an effort to create a safer work environment for drivers and improve data tracking, the Federal Motor Carrier Safety Administration (FMCSA) issued the Electronic Logging Device (ELD) rule (49 CFR § 395.) As a result, ELDs are required in commercial motor vehicles (CMVs) effective December 2017 (49 C.F.R § 395.8.)

Who is exempt from the ELD rule?

Truck Drivers who use the timecard exception are not required to keep records of duty status (RODS) or use ELDs. Additionally, the following drivers are not required to use ELDs; however, they are still bound by the RODS requirements in 49 CFR 395 and must prepare logs on paper, using an Automatic On-Board Recording Device (AOBRD), or with a logging software program when required:

  • Drivers who use paper RODS for not more than 8 days out of every 30-day period.
  • Drivers who conduct drive-away-tow-away operations, where the vehicle being driven is the commodity being delivered.
  • Drivers of vehicles manufactured before 2000.
