About National Defense Transportation Day
National Defense Transportation Day is a U.S. patriotic and national observance associated with the third Friday in May. The current federal statute, 36 U.S.C. §120, requests that the President issue a proclamation each year designating that Friday.
The observance recognizes the role of transportation systems and transportation workers in community life, the economy and national defense.
Why National Defense Transportation Day matters
Its federal status comes from the U.S. Code’s observance framework, not from the federal holiday schedule. The statute calls for recognition and appropriate ceremonies; it does not create a general day off for federal employees or the public.
The observance can be used to learn how roads, rail, ports, aviation and other transportation networks support both everyday movement and emergency or defense logistics.
History of National Defense Transportation Day
Congress approved the original joint resolution on 16 May 1957. President Dwight D. Eisenhower issued Proclamation 3183 that day and designated Friday, 17 May 1957, as the first National Defense Transportation Day.
The observance was later recodified in Title 36. Section 120 now requests an annual presidential proclamation designating the third Friday in May.
Later presidential proclamations have continued to recognize transportation infrastructure and the people who build, operate and maintain it.
