Which statement best describes the PMCS checks performed daily?

• A. Before PMCS
• B. During PMCS
• C. After PMCS
• D. All three stages (Before, During, and After PMCS)

Answer: (D)

PMCS is a three-stage routine: before operation, during operation, and after operation. Checking before starting ensures the vehicle is safe and roadworthy—fluid levels, tire condition, lights, and obvious defects are verified. Checking during operation helps catch issues that emerge as the vehicle runs—unusual sounds, overheating, performance changes, or abnormal gauge readings. Checking after operation reveals any problems that appeared during use and ensures the vehicle is left in a safe, serviceable state for the next use—look for leaks, looseness, or damage and secure or note items for maintenance. Because problems can show up at different times, the daily PMCS that ensures readiness and safety should cover all three stages.
