Use the whole shift as the test case
A useful ready-mix pilot includes more than the road between the plant and the construction site. Build a sample day with loading, arrival, waiting, discharge, return travel and cleanup. Record what the driver is actually doing at each stage rather than assuming that every stationary interval is rest.
The question for the ELD evaluation is whether the driver and office can understand that sequence in the record. Batch quality, drum operation, water additions and delivery-volume records belong to their own equipment and processes; an ELD installation alone does not provide those measurements.
Review these stages with the driver and plant team
| Stage | Question for the pilot | Keep separate from the ELD check |
|---|---|---|
| Plant loading | Is the correct driver assigned to the truck before the trip? | Mix specification and batch ticket |
| Site queue | What duties does the driver perform while waiting, and how are they recorded? | Assumptions that all waiting is off duty |
| Discharge | Can the reviewer distinguish road travel from the driver’s work at the site? | Concrete volume or drum-speed measurement |
| Return and washout | Does the review include work after the customer delivery? | Wastewater and material-disposal records |
| Next load or relief driver | Is the next truck or driver assignment clear? | Production scheduling and dispatch optimization |
These questions define a trial worksheet. They do not prescribe a duty status without knowing the actual work and applicable rule. Have the person responsible for the carrier’s hours-of-service decisions resolve that part of the procedure.
Confirm the truck and office configuration
The Factor FRS manual describes driver logs and office review. Ask Factor ELD to show those tasks using the specific product proposed for your fleet. Include the truck’s engine and connector details, phone or tablet version, account roles and any relief-driver arrangement.
Observe a complete representative cycle before accepting the setup. A connected device at the plant does not alone establish how the combination behaves through an entire shift, and it does not verify mixer-body or PTO data integration.
Check ready-mix provisions separately
49 CFR 395.1(t) contains a specific ready-mixed-concrete provision concerning qualifying waiting time and the rest-break requirement. It is conditional, not a blanket exemption from all hours-of-service rules or ELD use. Other work during a waiting interval matters to that assessment.
Review the operation before selecting a rule configuration. Our ELD applicability guide provides a starting point. For a fleet containing several kinds of jobsite vehicles, use the broader construction fleet page; use the rollout checklist to assign training and support responsibilities.
Ready-mix questions
Does waiting to discharge always count as a qualifying break?
No. The applicable provision has conditions, including what the driver does during the interval. Establish the facts and have the carrier apply the rule instead of labeling every site queue as a break.
Does the ELD measure the amount of concrete delivered?
Not as part of the driver-log scope described here. Discuss any separate telematics or equipment integration explicitly and confirm its availability in the proposed product and plan.
