The acronym "ELD" stands for Electronic Logging Device, which is a critical tool for commercial drivers. ELDs are used to electronically record a driver's hours of service (HOS) in compliance with federal regulations. These devices must be connected to the vehicle and automatically record driving time, ensuring accurate tracking of the hours a driver is on duty or off duty.

Using an ELD improves the accuracy and efficiency of logging hours compared to traditional paper logs, which can be subject to human error and manipulation. The use of electronic logging helps both the driver and the fleet manager ensure compliance with regulations intended to promote safety on the roads by preventing driver fatigue.

Understanding ELDs is essential for anyone preparing for a career in commercial driving, as the implementation of this technology is a significant part of the trucking industry's approach to safety and regulatory compliance.
