Recommendations for driving laws vary by state. I would call the DMV in your state and ask. I think in some states they do take your license. Your doctor may be able to help you out also if it is an issue in the state in which you reside.
Monika, I would like the answer to that question too. My 15 year old daughter is hoping to get her license in a month, and she has vasovagal syncope. I'm not sure if the DMV asks those types of medical questions. I'm planning on taking her for her drivers test anyway. Even if she can't drive at this point, she will atleast be able to say, "she has her license." Another problem, is my daughter is scheduled to take drivers ed at her high school in January. I'm hoping they don't drop her from the class, most of her fainting episodes happen at school. If you get a chance please read the question I posted on 11/1/08, under the name cheermom15, and let me know what types of treatments you have been through. I hope you have had better success with your treatments.
Thank you
