Bridge Inspection Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
Q1. What is the primary objective of a routine bridge inspection?
- To determine future traffic needs
- To update design plans
- Evaluate the structural and functional condition
- Identify construction errors
- Evaluate the structural and functional condition
Rationale: Routine inspections focus on current condition and safety, not
design or traffic planning.Q2. Which federal regulation governs bridge inspection standards in the
U.S.? 1 / 4
A. AASHTO R17
B. ASCE 7
C. ISO 9001
D. FHWA NBIS
D. FHWA NBIS
Rationale: The National Bridge Inspection Standards (NBIS) regulate all
U.S. bridge inspection requirements.Q3. The smallest unit of a bridge that can be assigned a condition rating is
the:
- Structure
- Component
- Element
- Material
- Element
Rationale: Elements represent the smallest rateable items under element-
level inspection systems.Q4. Which type of inspection is performed at intervals not exceeding 24 months?
- Damage inspection
- Fracture critical inspection
- Routine inspection
- Underwater inspection 2 / 4
- Routine inspection
Rationale: NBIS requires routine inspections every 24 months.
Q5. A fracture-critical member is defined as one whose failure would result
in:
- Minor repairs
- Financial burden
- Total or partial bridge collapse
- Dynamic instability only
- Total or partial bridge collapse
Rationale: FCMs lack redundancy; failure can lead to collapse.
Q6. Chloride intrusion primarily affects which bridge component?
- Bearings
- Steel trusses
- Concrete decks
- Expansion joints
- Concrete decks
Rationale: Chlorides penetrate concrete and accelerate reinforcement
corrosion.Q7. What inspection tool measures the thickness of steel components nondestructively?
- Crack comparator
- Rebound hammer 3 / 4
- Ultrasonic tester
- Moisture meter
- Ultrasonic tester
Rationale: Ultrasonic devices measure steel thickness and detect internal
flaws.
Q8. A common sign of advanced rebar corrosion in concrete is:
- Spalling
- Delamination
- Map cracking
- Bleeding
- Spalling
Rationale: Corrosion products expand, causing concrete to break off (spall).
Q9. Which condition rating represents “serious condition” under NBIS?
- 3
- 6
- 9
- 0
- 3
Rationale: Rating 3 indicates serious deterioration requiring attention.
Q10. A bridge scour inspection focuses primarily on:
- Deck cracking
- Foundation stability
