Frequently Asked Questions

What other requirements were included in the rule?

In addition to mandating ELDs, the rule also spells out what type of supporting documents must now be kept by motor carriers. The requirement behind maintaining supporting documents in conjunction with the ELD is to help carriers identify all work time that should be logged as on-duty not driving.

A motor carrier must retain up to eight (8) supporting documents. These documents should have the following elements:

- Driver’s name or carrier assigned identification number*
- Date
- Location
- Time

*this can also be a truck number, if that truck number can be linked to a driver.

If a carrier does not have eight documents that contain all the above elements, they should keep any document that contains all the above elements except time, as that document would still be considered a supporting document.


The rule has five (5) categories of supporting documents. They are:

1. Bills of lading, itineraries, schedules, or equivalent documents that indicate the origin and destination of each trip
2. Dispatch Records, trip sheets/records, or equivalent documents
3. Expense receipts
4. Electronic mobile communication records (such as those through a fleet management system)
5. Payroll records, settlement sheets or equivalent documents regarding payment to a driver

Only drivers still on paper RODS will be required to keep toll receipts in the future.

Drivers are not required to keep all supporting documents in their possession for roadside enforcement. However, if they have them available in the cab of their truck, they must provide them to roadside enforcement personnel if requested. A driver only has to provide the document in the form they have available to them at the time of the request.                                                                             

Motor carriers are required to keep these supporting documents for six months - the same period as the electronic or paper logs.
