Final answer:
The minimum number of months a sailor's base driving privileges could be revoked after a DUI conviction varies by jurisdiction and military branch. Typically, it could range from several months to over a year, depending on the individual case and driving history.
Step-by-step explanation:
A sailor who has been convicted of Driving Under the Influence (DUI) should typically expect to have their base driving privileges revoked for a certain period as part of the administrative and legal consequences for such an offense. The specific minimum number of months for revocation can vary by jurisdiction and the particular rules of the military branch the sailor belongs to. Policies might change over time or be subject to the specifics of their case and whether they have prior offenses. For example, in the United States Navy, base driving privileges may be revoked for a minimum duration that might range from several months to a year, or even more, depending on the severity of the incident and the sailor's driving history. It is important to note that this is separate from any civil penalties the individual may face.
