Can I block a FLEX vehicle in advance?
Once you’ve located a FLEX vehicle using our mobile app, you can block it free of charge for up to 30 minutes, giving you time to reach it.
You can only block the same vehicle one additional time if you do not access it within the first 30 minutes. A notification in the app will let you know when your first block is set to expire (less than 5 minutes remaining) allowing you to add a further 30 minutes to the blocking period.
