Final answer:
To find the number of vehicles needing LOFRs at a branch, one would use the branch's vehicle management system or fleet management software, which provides vehicle maintenance records and scheduled service reports.
Step-by-step explanation:
The number of vehicles that need LOFRs (Lube, Oil, Filter, and Rotate services) at a specific branch can typically be checked using the branch's vehicle management system or fleet management software. This system often contains detailed records of each vehicle's maintenance history and scheduled services. Employees at the branch would need access to this system and should search for or generate a report specific to LOFRs due or overdue. This process can vary depending on the software used, so referencing the system's user manual or consulting with a supervisor may be necessary for precise instructions.
