| Usage policy | Rating limit may apply outside of the polling frequency or if the service is degraded. |
| Polling frequency | Clients must not poll more frequently than 60 seconds. |
| Latency | Current location can be delayed from the vehicle due to cellular network coverage. |
| Retry timeout | The client should timeout a request at 30 seconds. A retry delay, of at least 2 minutes, should be used on timeout or 503 response code to not unnecessarily load the system. |
| Transport | EROAD will provide an HTTPS REST service endpoint using SSL. This will provide a 128bit encrypted link. |
