CSA data is collected from which of the following sources?

• A. Roadside inspections
• B. Law enforcement crash reports
• C. FMCSA investigations
• D. All of the above

Answer: (D)

CSA data comes from multiple sources to give a complete picture of safety. Roadside inspections record violations and out-of-service conditions observed during checks, and these results feed into the Safety Measurement System. Law enforcement crash reports provide details about crashes involving commercial vehicles, including severity and contributing factors, helping to identify risk patterns. FMCSA investigations add information from formal reviews and enforcement actions, such as compliance audits and vehicle inspections. Because CSA relies on all these data streams, the best choice is that data is collected from all of the above. This multi-source approach lets FMCSA identify high-risk carriers and drivers and target interventions effectively.
