What Type of Information Do Electronic Logging Devices Record?

By December 18, 2017, a majority of commercial vehicle operators will need to make the switch to electronic logging devices (ELDs). Drivers may also wonder what kind of information these devices store prior to using them. Modern ELDs can record various types of data at different intervals.

Date and Time

One of the key pieces of data that ELDs record is the date and time of when a vehicle is put in motion and stops for maximum accuracy.

Location Information

In addition to the date and time, ELDs also record the specific location of the vehicle at certain intervals, giving a clear picture of where the CMV has been as well as when.

However, these devices aren’t precise enough to identify street addresses, instead relying on the conversion of automatically captured vehicle positions in longitude/latitude coordinates into geo-location information. This data indicates the approximate distance and direction to an identifiable location corresponding to the name of a city, town, village, and state abbreviation.

Vehicle Miles

ELDs also record mileage throughout the vehicle’s travels, which needs to correspond with other metrics.

These devices will only start recording in driving mode once the vehicle reaches the threshold of five miles per hour. If the vehicle slows to zero miles per hour and remains stopped for three consecutive seconds, the device will stop recording.

Driver, Authenticated User, Vehicle, and Motor Carrier Identification Information

To help ensure that only authorized individuals are using ELDs, they record all identification information about the driver, authenticated user, vehicle, and carrier.

Other Details About Data Recording

Here is some additional information about how ELDs record all of this data.

ELDs Capture All Entered Duty Statuses

Unlike older recording devices, such as handwritten RODS which could record data in minimum intervals of 15 minutes according to longtime industry and enforcement practices, ELDs record all entered duty statuses. This makes them much more accurate than older recording methods.

Location Data Records Every Hour

ELDs must record location data every 60 minutes when the vehicle is in motion, as well as when the driver starts and stops the engine, changes duty status, and indicates yard moves or personal use.

Drivers Must Indicate When Using CMVs for Personal Reasons

If at any time a driver operates a CMV for personal use, he or she must indicate when doing so using the ELD. This helps prevent inaccurate tracking of hours when off-duty.

Co-Drivers Can Make Entries When Not Driving

Drivers who aren’t currently operating the vehicle can make entries in his or her own records while the vehicle is moving. However, they are unable to switch driving roles on the ELD while in motion.

Complying with the FMCSA Final Rule

Through the recording of all of this data, drivers and carriers can more easily meet FMCSA compliance requirements.
