Which three wrecker services does Fairfax County use?

• A. Henry's, Willow Springs, and Oakridge
• B. Henry's, Willow Springs, and Redwall
• C. Redwall, Willow Springs, and Maple Tow
• D. Henry's, Oakridge, and Redwall

Answer: (B)

This question tests recall of Fairfax County's contracted wrecker vendors and how dispatch is organized for broad coverage. The three wrecker services used are Henry's, Willow Springs, and Redwall. This specific trio is designated to ensure rapid response across different parts of the county and to provide sufficient capacity for multiple incidents. Other names listed aren’t on the official contractor roster, so they wouldn’t be used in standard operations.
