Core Responsibilities

Primary Functions

Conduct comprehensive, multi-point inspections on passenger vehicles, light-duty trucks, and commercial motor vehicles to ensure strict adherence to all applicable state, federal, and local safety and environmental regulations.
Thoroughly examine vehicle components and systems, including brakes, steering, suspension, chassis, frame, tires, wheels, lighting, and electrical systems, to identify wear, damage, or defects.
Utilize advanced onboard diagnostic (OBD-II) scanners and other computerized testing equipment to interrogate vehicle computer systems for fault codes and to assess the operational status of engine, transmission, and safety systems.
Perform and analyze results from state-mandated emissions tests, including dynamometer testing and exhaust gas analysis, to certify compliance with air quality standards.
Generate highly detailed and accurate inspection reports, meticulously documenting all findings, measurements, component conditions, and any identified non-compliance issues or required repairs.
Verify vehicle identification numbers (VINs) against official documentation and check for signs of tampering or alteration to confirm vehicle identity and legal status.
Interpret and apply complex technical manuals, vehicle recall notices, and evolving regulatory bulletins to ensure inspection procedures are current and comprehensive.
Clearly communicate inspection results, required repairs, and safety implications to vehicle owners, operators, or service center staff in a professional and understandable manner.
Make definitive pass/fail judgments on vehicle roadworthiness based on established criteria, and issue official inspection certificates, stickers, or rejection notices accordingly.
Maintain the calibration, cleanliness, and operational readiness of all inspection tools, diagnostic equipment, and testing bays to ensure consistent and accurate results.
Investigate and report on vehicles involved in accidents to assess pre-existing conditions, component failure, or non-compliant modifications that may have contributed to the incident.
Provide expert testimony in legal or administrative hearings regarding inspection findings, procedures, and regulatory interpretations when required.
Conduct random and scheduled audits of licensed inspection stations to ensure their compliance with state regulations, equipment standards, and proper procedural conduct.
Measure and document key vehicle attributes such as brake lining thickness, tire tread depth, and headlight aim, comparing them against legal minimums and manufacturer specifications.
Evaluate the structural integrity of a vehicle's frame and unibody, looking for evidence of collision damage, improper repairs, or corrosion that could compromise occupant safety.
Review and approve or deny applications for vehicle modifications, ensuring that any alterations to the suspension, engine, or exhaust system do not violate safety or emissions laws.
Maintain a secure and organized log of all inspections performed, including vehicle details, results, and certificate numbers, for auditing and record-keeping purposes.
Educate vehicle owners and the public on the importance of regular vehicle maintenance, safety checks, and the specific requirements of the inspection program.
Inspect specialized vehicle types, such as school buses, emergency vehicles, or vehicles modified for disabled persons, ensuring they meet heightened safety and equipment standards.
Stay continuously updated on new automotive technologies, including hybrid, electric (EV), and autonomous vehicle systems, and adapt inspection techniques accordingly.
