# Trailer Maintenance Status column (Drivers/Assets table)

> What the Trailer Maintenance Status column in Dispatch Planner v2 shows, which maintenance status wins when a trailer has several, and why the column can be blank.

Part of the [Dispatch Planner column reference](/en/help/loads-trips/dispatch-planner-columns).

The **Trailer Maintenance Status** column shows the most pressing maintenance item on the trailer in the **Trailer** column, such as an open work order or a service that is overdue. Use it to avoid sending a driver out with a trailer that needs to go into the shop.

## At a glance

| | |
| - | - |
| **Table** | Drivers/Assets |
| **Shown by default** | Yes |
| **Sort** | Yes |
| **Filter** | Pick one or more statuses from a list |
| **Who sees it** | Everyone who can open Dispatch Planner v2 |
| **Edit in the grid** | No. The status updates on its own from the trailer's work orders and scheduled maintenance. |

## What does each status mean?

The table shows the status names without spaces. The asset sidebar shows the same statuses as **Awaiting Service** and **In Shop**.

| Status | Meaning |
| - | - |
| **AwaitingService** | A work order on the trailer is open and has not started. |
| **Overdue** | A scheduled service has come due, and its due date has passed. |
| **Upcoming** | A scheduled service has a due date that is still ahead. |
| **InShop** | A work order on the trailer is in progress. |
| **Completed** | A maintenance item on the trailer is marked completed. |

The status describes the trailer in the **Trailer** column, which is the trailer on Driver 1's trip with the latest delivery date.

## Which status shows when a trailer has several?

A trailer can have several maintenance items at once. The column shows one of them, checked in this order:

1. **AwaitingService**
2. **Overdue**, only while its due date is in the past
3. **Upcoming**, only while its due date is in the future
4. **InShop**
5. **Completed**

A trailer with an open work order shows **AwaitingService**, even when it also has a work order in progress or a service that is overdue.

## Where do the maintenance items come from?

Maintenance items come from the trailer's work orders and scheduled maintenance, such as repair orders and scheduled maintenance synced from the [Fleetrock maintenance integration](/en/help/integrations/fleetrock-maintenance-integration).

When a work order is finished, it is removed from the trailer, so it drops out of this column instead of showing **Completed**. A work order that covers a scheduled service also clears that service from the trailer.

## Why is the column blank, or showing a status I did not expect?

**The trailer has no maintenance items.** If the trailer has no open work orders and no scheduled service that qualifies, the cell is blank. The cell is also blank when none of Driver 1's trips has a trailer.

**A scheduled service that has not come due does not show.** **Upcoming** shows only for a service with a due date in the future. Scheduled maintenance from Fleetrock that has not come due yet carries no due date, so it does not appear here. Once Fleetrock reports the service as due, it shows as **Overdue**.

**The filter matches the status shown.** Filtering by **Overdue** finds trailers whose column shows **Overdue**. A trailer with an overdue service and an open work order shows **AwaitingService**, so it does not match.

**Sorting is alphabetical.** Sorting orders the status names alphabetically, not by urgency. Drivers with no trailer maintenance status sort last.
