Directs the Secretary of Transportation to withhold a specified percentage of the highway apportionment of any State which is not implementing by FY 1992 a random illicit drug testing program which includes: (1) random testing of individuals applying for a driver's license; and (2) a minimum driver's license suspension period for individuals convicted of illicit drug offenses. Directs the Secretary to report to the Congress on the effectiveness of such State programs.

Prescribes a period of availability for withheld funds in the event that a noncomplying State comes into compliance with this Act.
