All commands are responsible for adhering to DoD 4500.36-R and what other instruction regarding official use of vehicles?

• A. NAVSUPINST 11240.1
• B. OPNAVINST 11240.8G
• C. OPNAVINST 11200.1
• D. DoD 5200.2

Answer: (B)

Official use of government vehicles is addressed in two layers: a DoD-wide policy and the Navy’s own implementing instruction that puts that policy into Navy practice. DoD 4500.36-R provides the department-wide requirements for vehicle operations, covering who may use vehicles, how they’re used, safety, maintenance, and accountability. To apply that broad policy within the Navy, the service publishes a specific instruction on official vehicle use. For this topic, the Navy’s implementing instruction is OPNAVINST 11240.8G. It spells out Navy-specific rules—who may drive, which vehicles can be used for official business, trip approvals, safety requirements, passenger limits, and reporting obligations—so commands can consistently follow DoD policy while accommodating Navy needs.

The other options do not cover the Navy’s official vehicle-use rules in the same way; they relate to different areas or DoD functions and do not serve as the Navy’s official instruction for vehicle use.
