Refrigerated fleets need ELD workflows that preserve duty accuracy during appointments, temperature checks, washouts, loading, detention, and rejected loads. Reefer telemetry and ELD data serve different purposes.
What this means for your fleet
Keep temperature and cargo systems distinct from the official duty record while linking events for investigation. Dispatch should plan appointment risk without pressuring drivers to relabel waiting or work.
Worked operating scenario
A rejected refrigerated load produces temperature checks, washout, detention, redelivery, and an appointment change. The driver records actual duty activity, dispatch retains the delay context, and the fleet links—but does not merge—reefer telemetry and ELD records.
What a passing test includes
Check each item in the same scenario: Map temperature checks and cargo work; capture detention context; separate reefer and duty systems; plan appointment risk; test multi-stop and offline workflows. Note who reviewed the result, which current rule or product source was used, any exception, and what the fleet will do next.
What to check
Use this operating matrix before buying or configuring a system. A completed answer is more useful than a generic feature check.
| Check | How to verify |
|---|---|
| 1. Map temperature checks and cargo work | Retain temperature-check, reefer inspection, cargo work, waiting and driving events with timestamps, locations, original statuses, and reviewer. |
| 2. Capture detention context | Keep appointment, arrival/departure, dock and detention times, messages, work performed, actual statuses, annotations, and dispatch disposition. |
| 3. Separate reefer and duty systems | Map reefer and ELD fields, systems, owners, timestamps and permissions; retain test data and prove that reefer events do not overwrite duty records. |
| 4. Plan appointment risk | Attach appointments and route plan, projected/actual times, HOS risk point, dispatch adjustment, exception, reviewer, and final result. |
| 5. Test multi-stop and offline workflows | Run a multi-stop offline scenario; keep disconnect/reconnect times, queued events, gaps or duplicates, status continuity, recovery, defects, and retest. |
Three checks before a route or rollout
- Applicability: Identify the driver, vehicle, trip, commerce, jurisdiction, and exact rule used for the decision.
- Operations: Rehearse the status, assignment, connection, and evidence exceptions most likely on this route.
- Follow-through: Name who reviews daily exceptions, trains drivers, maintains devices, and preserves records.
Limits and exceptions
This guide does not decide a fact-specific legal exception, certify a record, or guarantee a compliance, safety, cost, or audit outcome. Keep the original ELD record and any edit history. Use the current official rule for applicability and the exact installed-device manual for screen-by-screen actions.

Test the workflow on a representative route
Bring a vehicle, driver, route, mobile device, and the operation-specific exception scenario described in this guide. Factor ELD can demonstrate its current product; rule applicability remains a fleet compliance decision.
