Preventing problems is always better than fixing them—especially when it comes to commercial trucks. Truck preventive maintenance is a proactive approach that involves regularly scheduled service to keep vehicles in peak condition. For fleet managers and owner-operators alike, it’s the cornerstone of a reliable, cost-effective trucking operation.

What Is Preventive Maintenance for Trucks?
Preventive maintenance (PM) is a scheduled servicing routine designed to detect and correct potential issues before they become serious. Rather than waiting for something to break, preventive maintenance ensures each system in your truck gets the care it needs at the right intervals.

Benefits of Truck Preventive Maintenance

Creating a Preventive Maintenance Schedule
The best PM programs are tailored to the truck’s make, model, usage, and mileage. Common intervals include:

Every 5,000–7,500 miles: Oil changes, fluid checks

Every 15,000–30,000 miles: Brake inspections, transmission service

Every 50,000+ miles: Suspension checks, air system inspections
