ECT has developed a Safety Measurement Index (ECT Index) to evaluate carriers' safety performance. The ECT Index consists of 5 categories - Unsafe Driving, Hours of Service Compliance, Driver Fitness, Vehicle Maintenance, and Controlled Substances/Alcohol. It analyzes carriers' roadside inspection violations and safety event data to calculate a percentile score for each category, which determines the carrier's overall ECT Index rating and identifies any categories that exceed intervention thresholds. Carriers must have a satisfactory ECT Index rating to work with ECT, helping ensure freight is entrusted to safe carriers and reducing liability risks.
