The JTR implements policy and laws establishing travel and transportation allowances of Uniformed Service members and Department of Defense (DoD) civilian travelers. It also implements station and certain other allowances. The JTR has the force and effect of law for travelers, and implements statutory regulations and law for DoD civilian travelers. Organizations are expected to take appropriate disciplinary action when travelers willfully fail to follow the JTR. However, unless stated otherwise in the JTR, the disciplinary action cannot be in the form of refusal to pay appropriate travel and transportation allowances.
