This observance was introduced 1957, when Congress designated the third Friday of May as National National Defense Transportation Day. The request was updated in 1962 and the whole week was included within the holiday, that is why the third Friday falls as a part of National Transportation Week.

Every year the President of the USA issues a proclamation, that designates the third Friday of May as the day for observance. Appropriate ceremonies are held to recognize the importance of countries' transportation system and maintenance of its facilities for needs of the U.S. in national defense and in the time of peace.
