A bill to amend title 23, United States Code, to authorize a State under the national minimum drinking age provision to allow the purchase and consumption of an alcoholic beverage on the premises of certain establishments by any person who is eighteen, nineteen, or twenty years old, and for other purposes.

Amends the national drinking age law to provide that no apportionment of Federal-aid highway system funds shall be withheld from a State in which 18-, 19-, or 20-year old persons may lawfully purchase alcoholic beverages from an establishment authorized to sell such beverages for consumption on its premises.

Directs the Secretary of Transportation to apportion Federal-aid highway system funds which have been withheld from a State even if 18-, 19-, or 20-year old persons may lawfully purchase alcoholic beverages from such an establishment.

Authorizes the Secretary to add eligibility criteria to basic and supplemental grants to States which implement alcohol traffic safety programs. Identifies such criteria as: (1) the establishment of mandatory education programs for new operators of motor vehicles and persons convicted of driving while intoxicated; and (2) the establishment of comprehensive education programs for employees and patrons of establishments authorized to sell alcoholic beverages for consumption on the premises.
