# Retrieve a vehicle check submission

> GET /dn/vehicle_checklist_submissions/{id} returns one vehicle check submission with every answer, photo link, and signature.

Fetch one vehicle check submission by its `id`, from [List vehicle check submissions](https://detrack.mintlify.site/api-reference/vehicle-checks/list.md). The response has the same fields as each submission in the list.

Photo and signature links expire about 15 minutes after the response, so download the files straight away.

> [!WARNING]
>
> **Known issue:** if the submission's checklist was deleted, this returns `500` ([DTR-7093](https://detrack.atlassian.net/browse/DTR-7093)).
