Quick checklist

  • Determine ELD applicability from the regulation itself — do not rely on a vendor's statement that the device is or is not required for your operation.
  • Review 49 CFR 395.1 for HOS exceptions and 49 CFR Part 395 Subpart B for ELD exceptions — they overlap but are not identical.
  • For the short-haul exception, verify all three conditions independently: 150 air-mile radius from reporting location, return to reporting location within the same work shift, and time records maintained in lieu of logs.
  • Check HOS exceptions and ELD exceptions separately — a driver can qualify for a HOS exception without qualifying for the ELD exception, and vice versa.
  • For Part 382 drug and alcohol testing, confirm which drivers operate CDL-required commercial motor vehicles in interstate commerce — that is the applicability trigger.
  • Document the specific rule basis for each exception in a written applicability note in the audit packet — verbal explanations are not records.

Why this matters

The phrase where applicable is the source of many compliance gaps. When a carrier or driver assumes a rule does not apply without checking the specific conditions, the audit packet may be missing records that were actually required, or may contain records that do not match the exception the carrier is claiming. Both create problems: missing records look like a compliance failure, and misidentified exceptions raise questions about whether the carrier understands its own obligations. The practical answer is a written applicability note — a short document that identifies which rule applies or does not apply, which specific exception or threshold is being used, and the date the review was done. That note travels with the audit packet and answers the examiner's question before it is asked.

What to prepare

Area Records to gather
ELD applicability notes
  • ELD required: note the ELD provider, confirm the device is registered, and confirm the transfer/display function has been tested
  • Short-haul exception claimed: document the 150 air-mile radius from the reporting location, the return-to-reporting-location condition, and the time record maintained in lieu of a log (49 CFR 395.1(e)(1))
  • Driveaway-towaway exception claimed: note the regulation basis (49 CFR 395.1(e)(2)) and the specific vehicle type
  • Other exceptions: write the CFR citation and a brief statement of the operating conditions that qualify
  • Annual review of ELD applicability when routes, vehicles, or operations change
HOS applicability notes
  • Rule set in use: property-carrying rules (11/14 hour) or passenger-carrying rules, as applicable
  • Short-haul exception (49 CFR 395.1(e)) conditions documented if used
  • Agricultural operations exception or other 395.1 exception notes saved with supporting records
  • Supporting documents retained when HOS logs or ELD records are not required: fuel receipts, bills of lading, scale tickets for the trip
  • Driver instructions saved showing which rule set and which exceptions apply to their regular operation
Part 382 drug and alcohol applicability notes
  • Covered-driver list: CDL holders operating commercial motor vehicles as defined in 49 CFR 383.5 in interstate commerce
  • 26,001-pound GVW or GVWR threshold checked for vehicles that may or may not require a CDL
  • Non-covered drivers separated from the drug and alcohol testing records and program enrollment
  • Owner-operator driving their own vehicle as the sole driver: still covered under Part 382 and must be enrolled in a random testing consortium
  • Written applicability note filed with the drug and alcohol program documents

Common gaps

  • A carrier claims the short-haul exception but keeps no time records — the exception requires records in lieu of logs, not an absence of records.
  • ELD exceptions and HOS exceptions are treated as the same determination when they have separate conditions in the regulations.
  • Part 382 is applied to every driver without checking covered-driver status, or skipped entirely for CDL drivers who actually are covered.
  • The reason a rule is not applied exists only in the owner's memory — there is no written note in the file.

Before / During / After audit

Before

  • Create a written applicability note for every exception being used, linked to the specific CFR citation.
  • Review applicability whenever routes, vehicles, drivers, or operations change.
  • File the applicability note with the related record category in the audit packet.

During

  • Present the applicability note with the related records — do not rely on verbal explanations.
  • Avoid blanket statements like 'we are exempt' without referencing the specific exception and the conditions that apply.

After

  • Update applicability notes when the operation changes.
  • Train dispatch and drivers on the specific exception in use — not a general 'we do not need that' assumption.

FAQ

Does claiming the short-haul exception mean no records are required?

The short-haul exception under 49 CFR 395.1(e) removes the daily log and ELD requirement, but it does not remove the record-keeping requirement. The carrier must maintain time records showing each driver's start and end times, and those records must be kept for six months. Carriers that claim the exception but keep no time records at all have not satisfied 395.1(e)(1). The confusion usually comes from thinking the exception means no paperwork — it means different paperwork, specifically time records instead of duty status logs.

Can an owner-operator skip Part 382 drug and alcohol testing if they are the only driver?

An owner-operator who is also the sole driver is still subject to Part 382 drug and alcohol testing if they operate a CDL-required CMV in interstate commerce. The rule at 49 CFR 382.103 covers every employer and driver operating in that category — there is no single-driver exclusion. Owner-operators typically satisfy the random testing requirement by enrolling in a testing consortium, which operates a random pool across multiple members and selects at the required rate. The gap that shows up in audits is not misunderstanding the rule — it is assuming that having only one driver means the program does not apply, which it does not.

If an operation changes from local to interstate, when does the ELD rule apply?

The ELD requirement applies whenever the driver is subject to 49 CFR Part 395 hours-of-service recordkeeping requirements for an interstate operation. The change in applicability is not prospective — if a carrier that previously operated entirely within one state begins operating interstate, the ELD obligation attaches to the first trip that crosses into interstate commerce. Carriers that add an interstate route should review ELD applicability before that route begins, update the applicability note, and confirm the ELD is registered and functioning.
