A partner transport operator that sends vehicles into a principal contractor's site can handle driver selection, dispatch, and pre-departure alcohol checks under its own procedures. But if a vehicle passes through the principal contractor's entry gate and moves around loading and unloading areas or production facilities, the principal contractor also needs to know which vehicles and drivers are being deployed to which work that day. What is needed here is not a simple "done" message from the partner, but a way to confirm that the scheduled trips and the check procedure for each actual driver are correctly linked.
An alcohol check is a procedure for confirming, in a set way, whether a driver has been drinking before a trip. The partner handles driver checks and its own records, and the principal contractor cross-checks the list of actual trips coming onto the site against whether checks have been completed. You also need to decide in advance who will adjust a vehicle's entry, loading, or unloading assignment when the information does not match or a vehicle's check is not finished, so that check results lead to action on site.
Match by trip, not by driver name
If you manage check targets by driver name alone, confusion can arise when two drivers share a name or when one driver makes several trips a day. Defining each trip as a bundle of the trip date and time slot, vehicle identification, driver, and the entry or loading/unloading destination lets the principal contractor and the partner cross-check the same item.
The reference should be the final list just before actual deployment, not the original dispatch schedule. If only the original list remains after a driver change, vehicle change, or trip cancellation, a canceled trip may be treated as unchecked, or a replacement driver's check status may be wrongly linked to the original driver. It is necessary to set both when the partner reports changes and when the principal contractor finalizes the day's deployment list.
Send the principal contractor the status needed for deployment decisions
The information the principal contractor receives routinely can consist of the status needed to make dispatch and on-site deployment decisions, such as whether the driver completed the check before that trip, whether the check is in progress, or whether deployment was put on hold because the check was not confirmed. Adding information that identifies the trip and the time of the check makes it possible to confirm which vehicle and which deployment a report refers to.
On the other hand, routinely receiving individual readings, test screens, or the full original records kept by the partner is a matter that requires a separate review of necessity and the scope of data processing. The principal contractor's purpose is to cross-check whether trips entering the site have completed checks, while the partner's purpose may be to keep its own check records. If original records must be cross-checked in exceptional cases, setting out in an operating document who may check them, for which trips only, and to what extent can reduce unnecessary transfers of data.
| Check stage | What the principal contractor checks | Actions to align with the partner |
|---|---|---|
| Pre-departure report | Completed, in progress, or on-hold status for each trip | Report status based on the final driver and vehicle |
| Same-day cross-check | Whether the principal contractor's deployment list matches the report | Report again reflecting driver or vehicle changes |
| Mismatch | Unchecked trips and the responsible contact | Discuss putting deployment on hold or a replacement trip |
"Completed" in the table should be used to mean that the check procedure agreed with the partner has been finished. Even if different companies use the same "completed" flag, its meaning can differ if the procedure that produces it differs. It is better for contracts or operating standards to set out separately the checks and records the partner performs, the dispatch information the principal contractor cross-checks, and the order of notification when there is a mismatch.
When something is missing, first judge whether the vehicle could actually be deployed
As a hypothetical case, consider a truck scheduled to enter in the morning that is on the principal contractor's final deployment list but missing from the status report sent by the partner. The fact to observe here is not only that the report was late. You should first look at whether the vehicle could enter without a check, and whether the driver was changed but only one of the partner's or the principal contractor's lists was updated.
Depending on what you find, you can ask the person at the partner with authority to change dispatch to resend the final driver and check status, and remove the vehicle from the list of vehicles cleared to enter or work until the status is confirmed. If a replacement vehicle is deployed, the replacement driver and new vehicle are also set up as a separate trip and run through the same procedure. The completion criterion in this case is not for the principal contractor's staff to fill in the blank by guesswork, but for the partner to re-identify the actual driver and vehicle, reply with the status, and match it to the principal contractor's final list.
More important than the contact who receives normal reports is the contact chain for handling such mismatches. A practical approach is to designate a dispatcher at the partner who can change drivers or vehicles, and a person at the principal contractor who can adjust entry, unloading, and on-site deployment. To keep processing from stalling during night trips or when staff are absent, you can also set backup contacts and the order of handling when no one can be reached.
Cross-check a sample of trips to test the link between reports and records
Instead of the principal contractor copying and keeping the original records for every trip, it can consider selecting some trips at set times, or after a mismatch occurs, and cross-checking whether the reported content links to the records held by the partner. The goal is not to collect drivers' personal information widely, but to confirm that the completed status sent by the partner is based on actual trips.
If the cross-check finds that vehicle information was linked to a different trip or that a driver change was not reflected, it is hard to end things by correcting only that trip. You need to decide how far to re-check reports prepared in the same way during the same period, and follow up by tightening when dispatch changes are communicated and by whom. Conversely, if the link is consistently confirmed, the principal contractor gains a basis for keeping a reporting system centered on status information.
Keep the verification path going even when the transport operator changes
When a new partner comes in, handing over the existing report form is not enough. You need to set, in line with the actual dispatch flow, when the new company finalizes drivers and vehicles, to whom it sends changes, and who adjusts the entry or work deployment of unchecked vehicles. Even with the same form, if each company finalizes dispatch at a different time, the points where omissions occur will also differ.
When a contract ends or the transport operator changes, the operating procedure can also cover who keeps the existing trip reports, how the principal contractor requests information when past trips need to be checked, and how the previous staff's sharing permissions are cleaned up. Keeping the division of roles in which the partner performs driver checks and records and the principal contractor cross-checks actual deployed trips against completed status makes it clear, when a problem arises, who adjusts vehicle deployment and who establishes the facts.
Article 36 of Korea's Occupational Safety and Health Act sets out risk assessment, which involves identifying hazards and risk factors at a workplace and establishing and implementing improvement measures to reduce the risk. If missed checks or mismatched dispatch information keep recurring as partner transport operators deploy vehicles, you can handle this by defining it as a risk factor to manage within the trip process and improving the contact system and cross-check procedure.
