# §395.26. ELD data automatically recorded.

- (a) **In general.** An ELD provides the following functions and automatically records the data elements listed in this section in accordance with the requirements contained in appendix A to subpart B of this part.
- (b) **Data automatically recorded.** The ELD automatically records the following data elements:
  - (1) Date;
  - (2) Time;
  - (3) CMV geographic location information;
  - (4) Engine hours;
  - (5) Vehicle miles;
  - (6) Driver or authenticated user identification data;
  - (7) Vehicle identification data; and
  - (8) **Motor carrier identification data.**
- (c) **Change of duty status.** When a driver indicates a change of duty status under [§ 395.24(b)](/cfr/49/395.24.md?p=b), the ELD records the data elements in [paragraphs (b)(1) through (8)](#b-1..b-8) of this section.
- (d) **Intermediate recording.**
  - (1) When a commercial motor vehicle is in motion and there has not been a duty status change or another intermediate recording in the previous 1 hour, the ELD automatically records an intermediate recording that includes the data elements in [paragraphs (b)(1) through (8)](#b-1..b-8) of this section.
  - (2) If the intermediate recording is created during a period when the driver indicates authorized personal use of a commercial motor vehicle, the data elements in paragraphs [(b)(4)](#b-4) and [(5)](#b-5) of this section (engine hours and vehicle miles) will be left blank and [paragraph (b)(3)](#b-3) of this section (location) will be recorded with a single decimal point resolution (approximately within a 10-mile radius).
- (e) **Change in special driving category.** If a driver indicates a change in status under [§ 395.28(a)(2)](/cfr/49/395.28.md?p=a-2), the ELD records the data elements in [paragraphs (b)(1) through (8)](#b-1..b-8) of this section.
- (f) **Certification of the driver's daily record.** The ELD provides a function for recording the driver's certification of the driver's records for every 24-hour period. When a driver certifies or recertifies the driver's records for a given 24-hour period under [§ 395.30(b)(2)](/cfr/49/395.30.md?p=b-2), the ELD records the date, time and driver identification data elements in paragraphs [(b)(1)](#b-1), [(2)](#b-2), and [(6)](#b-6) of this section.
- (g) **Log in/log out.** When an authorized user logs into or out of an ELD, the ELD records the data elements in paragraphs [(b)(1)](#b-1) and [(2)](#b-2) and [(b)(4) through (8)](#b-4..b-8) of this section.
- (h) **Engine power up/shut down.** When a commercial motor vehicle's engine is powered up or powered down, the ELD records the data elements in [paragraphs (b)(1) through (8)](#b-1..b-8) of this section.
- (i) **Authorized personal use.** If the record is created during a period when the driver has indicated authorized personal use of a commercial motor vehicle, the data element in [paragraph (b)(3)](#b-3) of this section is logged with a single decimal point resolution (approximately within a 10-mile radius).
- (j) **Malfunction and data diagnostic event.** When an ELD detects or clears a malfunction or data diagnostic event, the ELD records the data elements in paragraphs [(b)(1)](#b-1) and [(2)](#b-2) and [(b)(4) through (8)](#b-4..b-8) of this section.
