# Create a break in a transport (segment)

When you need to materialize a bulk breaking or a change of trucker, you can create a break in a segment. This will actually split the segment into two, with a new site that you specify, between initial start and end.\
\
Here is an exeample:

* for a simple transport going from A to B, there is one initial segment A -> B
* let's call the break site C
* after the break is created, we have 2 segments resulting:
  * A -> C
  * C -> B

\
If there was a trucker and some plates (vehicle and trailer) assigned to the initial segment, they will remain on the first segment (A -> C).\
When creating the break, you can also assign a trucker and plates for the nbew segment but this is not mandatory. If you decide to assign a trucker, you can also choose whether you want him to be notified with this new mission with the `send_to_trucker` booelan.\
\
Break creation is done using the /segments/{uid}/break/ endpoint.

Here is an exemple payload where we decide to just create a break and not assign to second segment:

```
{
  "site": {
    "address": {
      "name": "Brunel S.A.S. (Exemple)",
      "address": "7 la Loeuf du Houx",
      "city": "Vouzeron",
      "postcode": "18330",
      "country": "FR",
      "latitude": 47.273911,
      "longitude": 2.172278,
      "coords_validated": true
    }
  },
  "trucker_id": null,
  "vehicle": null,
  "trailers": [],
  "send_to_trucker": false
}
```

Trucker and plates assignment can be done later using the /segments/{uid}/assign/ endpoint.
