On May 16, 1957, Congress approved for the third Friday of May each year to be designated as National Defense Transportation Day. In 1962 Congress updated their request to include the whole week within which the Friday falls as National Transportation Week.

The President is requested to issue each year a proclamation to: designate the third Friday in May as National Defense Transportation Day; and urge people to observe the day by appropriate ceremonies that recognize the importance of the country’s transportation system and the maintenance of its facilities to serve the needs of the United States in times of peace and in national defense.
