You need to keep a valid driving licence, vehicle registration certificate and insurance on file at all times.
We track your vehicle's insurance expiry. Shortly before it runs out, rides can no longer be reserved with that vehicle and you're told so. Once it has expired, the vehicle can't take rides until a current policy is on file — check it again from Vehicles, or upload the new one.
Renew your driving licence and registration before they expire, too. Driving on an expired one is against the law, and keeping them current protects you as much as your riders.
Upload renewals from the Captain app. Review is usually quick.
