What does NBIS stand for and what is its primary purpose?

• A. National Bridge Inspection Standards; to rate bridges for toll or funding allocation.
• B. National Bridge Inspection Standards; to require regular, standardized inspections of all highway bridges to identify structural deficiencies and safety risks.
• C. National Bridge Inspection Standards; to deregulate inspections.
• D. National Bridge Inspection System; to monitor traffic loads on bridges.

Answer: (B)

NBIS stands for National Bridge Inspection Standards. Its primary purpose is to require regular, standardized inspections of all bridges on public highways to identify structural deficiencies and safety risks. This creates a uniform, nationwide approach so inspectors across states evaluate bridges using the same criteria and reporting methods, enabling timely maintenance and repairs and helping protect public safety. It’s not about toll ratings, deregulation, or monitoring traffic loads; those ideas don’t capture NBIS’s focus on systematic condition assessment and safety.
