Do I have to block a FLEX vehicle in advance to access one I find on the street?

Not at all. If the vehicle is available, you will be able to access it.

You will know if the vehicle is available by looking at the card reader:

a green flashing LED, the car is available
a red flashing LED, the car is already being used by another member
both green and red LEDs flashing, the car has been blocked for use by another member (that member could be you, if you already blocked the car)
