Which of the following factors is NOT included in the CSA measurement system for prioritizing carriers?

The CSA (Compliance, Safety, Accountability) measurement system is designed to evaluate the safety performance of commercial vehicles and their operators. It focuses on various safety and compliance-related factors to ensure that carriers maintain high safety standards. Among the factors included in this measurement system are accident history, traffic violations, and driver complaints, all of which reflect the operational safety and compliance of a carrier.

Driver complaints can affect a carrier's safety performance as they may indicate potential issues in how drivers are treated or how they operate their vehicles. However, annual gross revenue is not a factor considered in the CSA measurement system. The rationale is that gross revenue does not directly correlate with safety performance or compliance issues. The CSA system targets behavior and past performance indicators that have a more immediate impact on road safety, rather than financial metrics. Thus, while understanding a carrier's financial health is important, it does not influence the prioritization under the CSA framework.
