What is the minimum speed a bumper system is rated to withstand?

• A. 0 mph
• B. 2.5 mph
• C. 5 mph
• D. 10 mph

Answer: (B)

Bumper systems are built to handle small, life-like bumps without failing, so the rating reflects the minimum speed at which they’re guaranteed to hold up. The standard test speed represents a basic, real-world threshold for protecting the vehicle’s structure during minor contacts. Therefore, the bumper is rated to withstand at least 2.5 mph. A 0 mph rating wouldn’t test any impact at all, and higher ratings like 5 mph or 10 mph indicate protection for more severe impacts, not the minimum.
