An easy solution is to be sure to check for availability on the mobile app prior to going to a station. If you are at a station and there are no vehicles, all BlueIndy rental kiosks are linked. Present your badge at the kiosk. It will then guide you to nearby stations that have a car available. At that time you can reserve a car for a period of 30 minutes, after which time the car must be used or reservation canceled to avoid incurring a $5 penalty fee.
