Vehicle Maintenance BASIC
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
Vehicle Maintenance is the CSA BASIC tracking equipment-related violations identified during roadside inspections — brakes, tires, lights, exhaust, coupling devices, and frame issues. It is consistently among the top three violation categories nationally. Severity weights run 1 to 10. The BASIC is heavily influenced by equipment age and pre-trip inspection discipline. Carriers with elevated Vehicle Maintenance percentiles should standardize a pre-trip checklist (paired with the DVIR) and run quarterly fleet-wide preventive-maintenance audits. Investments in newer trailers and tractors typically pay off in measurable Vehicle Maintenance percentile reduction within two refresh cycles.
