NOTE: This guidance reflects minor correction(s) (e.g., for grammar, typographical errors, or consistency) made on March 10, 2022.




Question: What information should be in the supporting documents?

Guidance: Under 49 CFR 395.11(c)(2)(i), a supporting document must contain the following elements:

  • Driver name or carrier-assigned identification number, either on the document or on another document enabling the carrier to link the document to the driver. The vehicle unit number can also be used if it can be linked to the driver;
  • Date;
  • Location (including name of nearest city, town, or village); and
  • Time.

However, under §  395.11(c)(2)(ii), if a driver has fewer than 8 supporting documents containing these four data elements for a 24-hour period, a document containing all of the elements except time is considered a supporting document.
