Navajo Transit System
The Navajo Transit System (NTS) is a public transportation system that serves and operates on the Navajo Nation. The system currently operates 17 routes throughout the Navajo Nation and within Arizona, New Mexico and Utah. The system provides service to 41 of the 110 Navajo Chapter communities.

The NTS is a department of the Division of Transportation of the Navajo Nation Government. The NTS receives funding from the Arizona Department of Transportation, the New Mexico Department of Transportation, the Utah Department of Transportation, and the Federal Transit Administration.

The NTS has been criticized for frequent service interruptions. In 2017, the NTS had some federal grants suspended due to non-compliance with government protocol.

In 2018, The NTS announced a partnership with the Farmington Red Apple Transit system which allows riders to transfer between the systems free-of-charge in Kirtland, NM and Farmington, NM.

Due to the COVID-19 Pandemic, the NTS suspended service on March 18, 2020. Service was not resumed until a June 7, 2021 soft restart of routes 3, 5, 9, and 14.
