⚠️
Restrictions:

If the carrier is not enrolled in ELD visibility, vehicle will be null or an empty object, and eldEnrolled will be false.

If the carrier is not attached to the requesting client, vehicle will be null or an empty object and message will contain: "Carrier must be attached for fleet visibility".

If the vehicleId is invalid for the given dot or the vehicle is not currently available from the ELD provider, you may receive a 404-style response or an empty vehicle payload, depending on implementation:
