Prompted by increased fatality rates involving USPS-contracted motor carriers, the U.S. Postal Service sought to explore methods to improve contractor safety and compliance levels. CSS conducted a risk assessment and developed a Quality Assurance Program for USPS to review, monitor, and approve motor carrier performance. CSS identified motor carriers with compliance and safety problems, analyzed trends in carrier safety issues and operational problems, and provided the USPS with a clear, accurate program analysis. CSS also develop educational materials and strategies for corrective action to improve safety and performance for USPS-contracted motor carriers.
