Under the maintenance policy, Schedule A, B, and C is performed for buses at what mileage?

• A. 20,000 miles
• B. 24,000 miles
• C. 40,000 miles
• D. 36,000 miles

Answer: (B)

All three maintenance levels are designed to be completed at a single mileage milestone to streamline upkeep and ensure critical systems are checked together. Under this policy, Schedule A, Schedule B, and Schedule C are performed at twenty-four thousand miles, so a single service interval covers the comprehensive checks and tasks defined for all three levels. This approach helps catch wear and safety issues early while reducing downtime by combining the work into one session. The other mileage options don’t match the policy’s directive to perform all three schedules at the same milestone, so they wouldn’t reflect the intended maintenance practice.
