Annual Inspections With Defect Resolution Built In.
Sigma Fleet Services coordinates inspection scheduling, eligible annual commercial-vehicle inspections, defect documentation, repair approvals, and follow-up service through one organized workflow. Vehicle eligibility, inspector availability, certification requirements, and service location are confirmed before the inspection is scheduled.
An Inspection Date Should Never Be a Surprise.
Managing annual inspections vehicle by vehicle creates unnecessary risk. Expiration dates can be overlooked, vehicles may be unavailable when appointments are scheduled, and defects discovered during inspection can remain unresolved without a clear follow-up process. Sigma helps organize inspection activity around vehicle assignments, operating schedules, inspection-due dates, service locations, and defect-repair requirements.
Due-Date Visibility
Maintain an organized view of vehicles approaching their annual inspection date.
Fleet Scheduling
Stagger inspections so too many vehicles are not removed from operation simultaneously.
Vehicle Preparation
Review known defects and maintenance concerns before the scheduled inspection.
Defect Follow-Through
Move identified deficiencies through documentation, approval, repair, and reinspection when required.
Critical Systems Reviewed for Vehicle Readiness.
The applicable inspection scope depends on vehicle class, configuration, operating authority, jurisdiction, and inspection program.
Brake Systems
Review applicable service brakes, parking brakes, brake components, lines, hoses, warning systems, and related equipment.
Steering & Suspension
Inspect applicable steering components, suspension systems, springs, mounting points, and visible conditions affecting vehicle control.
Tires, Wheels & Rims
Review tire condition, tread, inflation, wheel integrity, fasteners, rims, and visible damage.
Lighting & Electrical
Inspect required lamps, reflectors, warning indicators, wiring conditions, and other applicable electrical components.
Fuel & Exhaust Systems
Review visible fuel-system conditions, leaks, securement, exhaust routing, and applicable exhaust-system components.
Windshield, Wipers & Glazing
Inspect applicable glazing, windshield condition, wipers, washers, and driver visibility.
Frame, Body & Securement
Review applicable frame members, body securement, doors, structural conditions, and cargo-related components.
Coupling Devices
Inspect applicable fifth wheels, pintle hooks, drawbars, safety devices, and other coupling components.
Emergency Equipment
Confirm the presence and condition of applicable emergency equipment required for the vehicle and operation.
Schedule. Inspect. Resolve. Document.
Identify
Confirm unit, VIN, class, location, history, mileage, and inspection-due date.
Confirm
Determine the applicable program, vehicle eligibility, inspector availability, setting, and documentation.
Schedule
Coordinate the appointment around vehicle availability, operating schedules, site access, and market capacity.
Inspect
A qualified inspector evaluates applicable vehicle systems and documents the results.
Review
Deficiencies and maintenance observations are communicated to the customer's designated contact.
Repair
Eligible corrective work is estimated, approved, scheduled, and completed through the appropriate mobile or shop workflow.
Complete
When required, repaired items are verified before the workflow is completed and documentation is issued.
The Inspection Is Not Finished When a Defect Is Found.
Maintenance Observation
A condition that may not prevent a passing result but should be monitored or scheduled for future attention.
Repair Recommendation
An item requiring corrective maintenance but not necessarily immediate vehicle removal, subject to the applicable standard and vehicle condition.
Inspection-Preventing Defect
A deficiency that must be corrected before the vehicle can satisfy the applicable inspection requirements.
Unsafe Condition
A condition requiring immediate operational review and appropriate corrective action before further use.
Complete the Inspection in the Appropriate Setting.
Mobile Inspections
Eligible inspections may be performed at the customer's operating location when the site, vehicle, equipment, inspector, and jurisdictional requirements allow.
Shop Inspections
Vehicles requiring specialized equipment, controlled conditions, significant corrective work, or services unavailable in the field should be inspected at an appropriate facility.
Combined Workflow
A vehicle may receive an initial inspection on-site and then be routed to the shop when defects require equipment or repairs unavailable through mobile service.
Manage the Calendar Across the Entire Fleet.
For larger and high-utilization fleets, Sigma can coordinate annual inspections as an ongoing program rather than a series of isolated appointments.
Build an Inspection ProgramMaintain the Documentation Behind the Inspection.
The motor carrier or vehicle operator remains responsible for determining which inspection requirements apply, maintaining required records, monitoring vehicle condition between inspections, and ensuring vehicles remain safe and compliant during operation.
Federal periodic-inspection requirements and inspector-qualification rules may apply to covered commercial motor vehicles, while state requirements may differ or apply in addition. Sigma does not represent that one inspection automatically satisfies every federal, state, or local requirement.
Local support across four operating markets.
Sigma Fleet Services coordinates eligible commercial-vehicle inspections from Pittsburgh, Zelienople, Northampton, and Binghamton. Inspector availability, mobile coverage, vehicle eligibility, and certification capabilities vary by market and jurisdiction.
Coordinate inspection scheduling, documentation, defect resolution, and follow-up service across your commercial fleet.
Build an inspection process that connects the calendar, the vehicle, the defect workflow, and the corrective service required to keep the fleet ready.
