Which choice is NOT a listed source of CSA data?

Which choice is NOT a listed source of CSA data?

• A. Roadside inspections
• B. Law enforcement crash reports
• C. FMCSA investigations
• D. Insurance claims

Answer: (D)

CSA data comes from official safety-related sources, not from private claim records. Roadside inspections contribute observed vehicle and driver violations, law enforcement crash reports provide details about crashes involving commercial vehicles, and FMCSA investigations (such as safety audits and compliance reviews) supply formal findings on carriers and drivers. Insurance claims aren’t used as a CSA data source because they’re not standardized, can be biased or incomplete, and don’t directly reflect regulatory safety compliance. That’s why insurance claims are not a listed source of CSA data.
