請問8老師和其他專家，H1B extension and drive license

請問8老師和其他專家，

我的HIB extension was filed to Vermont center, the receipt day is 08/15/2011. I haven't receive decision yet. the time frame shown is 2 months. But my I-94 was expired on 10/01/2011. So I am out of status, right? Is that dangerous?

Besides, my drive license was expired on the same day, 10/01/2011, Is there any way to get renewed or I can not drive until extension approved.

I am very worried and many thanks for all your help.
