If her BEST CORRECTED VISION is worse then 20/40 she may still be able to drive with a restricted license, the vision requirements vary state to state so check with your DMV.

Legal blindness is defined as best corrected visual acuity of 20/200 or worse in the better eye and/or a best corrected visual field of less than 20 degrees.

The definition of legal blindness refers to what vision is AFTER best correction with contacts and glasses.  If your daughter can be corrected to 20/20 to 20/40 and has her peripheral vision intact, she can legally drive.
