Merely getting married to a USC does not cancel your F-1 status* or grant you any other status. But if you stop attending classes**, that would end your status. If the DMV of your state verifies immigration status with USCIS, and the school reported your absence to USCIS (which they are supposed to do since the SEVIS implementation), the DMV would reject your application for a license after hearing from USCIS.
*[size=-2]Although you don't lose F-1 status by marrying a USC, you may have problems trying to use the F-1 visa to reenter the US after overseas travel.
**Attending classes in the summer break is optional for F-1 students, so if you attended school the entire previous semester, and have not graduated or otherwise terminated your enrollment, deciding to avoid summer classes would not harm your F-1 status[/size].
