National Defense Transportation Day is a United States observance that honors the critical role of transportation in supporting national security and economic prosperity. It highlights the contributions of professionals across the transportation industry—from logistics planners and truck drivers to railway engineers and aviation specialists—whose work ensures the efficient movement of people, goods, and military resources. The day also encourages public understanding of transportation’s role in both daily life and national defense.
What is National Defense Transportation Day?
National Defense Transportation Day was established in 1957 when the U.S. Congress authorized the President to proclaim the third Friday of May each year as a day to recognize the importance of transportation to national defense and the economy. It was later expanded into National Transportation Week to extend the focus and education efforts across multiple days.
This observance acknowledges how the infrastructure and workforce supporting air, land, sea, and rail transport are vital not only for commercial supply chains and travel, but also for military readiness, disaster response, and homeland security.
The day is supported by organizations like the National Defense Transportation Association (NDTA), government agencies, educational institutions, and transportation industry leaders, who use the occasion to promote awareness, innovation, and workforce development in the sector.
When is National Defense Transportation Day?
National Defense Transportation Day is observed annually on the third Friday in May. In 2026, it will fall on Friday, May 16th.
It also serves as the focal point for National Transportation Week, which runs from Sunday, May 11 to Saturday, May 17, 2026.

Why National Defense Transportation Day Matters
Transportation is the backbone of national security and the economy. In times of conflict, crisis, or emergency, the ability to swiftly and reliably mobilize people, equipment, and supplies can be the difference between success and failure. Likewise, in daily life, robust transportation systems connect communities, support commerce, and sustain livelihoods.
National Defense Transportation Day ensures that the often-invisible work of transportation professionals is recognized and that the next generation understands the value of careers in logistics, engineering, planning, and safety management.
