What must be obtained before making alterations to department vehicles?

Before making alterations to department vehicles, it is essential to obtain approval from the Fire Logistics Supervisor. This is correct because the Fire Logistics Supervisor is responsible for overseeing the management and maintenance of fire department vehicles. They ensure that any modifications align with operational requirements, safety standards, and budget considerations specific to the fire department.

The other options do not reflect the direct chain of command or responsibility concerning vehicle alterations. For instance, while the Fire Chief holds overarching authority within the department, the day-to-day management of vehicle modifications falls under the purview of the Fire Logistics Supervisor. Similarly, the City Manager is not typically involved in the specifics of departmental vehicle alterations and would focus on broader administrative and policy decisions. Lastly, while the Vehicle Maintenance Department plays a crucial role in maintaining the vehicles, the approval for alterations should be directed through the Fire Logistics Supervisor to maintain organizational structure and accountability.
