Truck Preventive Maintenance: The Key to Avoiding Downtime

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.

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