Signs Your PM Program Needs Attention
Overdue PM Interval
Exceeding recommended PM intervals increases risk of undetected wear, fluid degradation, and developing failures.
Increasing Breakdown Frequency
More frequent unplanned repairs indicate PM intervals or depth are insufficient for your operating conditions.
DOT Violations Increasing
Inspection failures for brakes, lights, tires, or air leaks indicate PM program gaps.
Fluid Consumption Increasing
Rising oil, coolant, or DEF consumption between services indicates developing problems that PM should catch early.
Driver Complaints Increasing
More DVIRs with deficiencies suggest maintenance isn't keeping pace with vehicle condition.
Fuel Economy Declining
Dropping MPG across the fleet indicates maintenance issues — tire pressure, alignment, brake drag, filter restriction.

Why Preventive Maintenance Matters
Preventive maintenance is the most cost-effective strategy for managing commercial vehicle reliability. A structured PM program catches developing problems early, extends component life, maintains compliance, and keeps your trucks generating revenue.
Tiered Approach
PM-A catches basic issues frequently. PM-B adds depth semi-annually. PM-C provides comprehensive evaluation annually. Each tier builds on the previous one.
Condition-Based Decisions
PM inspections generate data — measurements, observations, trends. This data drives repair decisions based on actual condition rather than guesswork.
DOT Integration
PM-C mirrors FMCSA annual inspection criteria. When PM-C is current, your annual inspection becomes verification of work already performed.
Cost Per Mile Reduction
Structured PM reduces total maintenance cost per mile by preventing expensive breakdowns and extending component life. The math is clear and consistent.
