What does Anti-lock Braking System (ABS) do on fire apparatus?

• A. Prevents wheel lock-up in wet or icy climates, maintaining steering control
• B. Increases stopping distance on all surfaces
• C. Reduces brake temperature but not distance
• D. Only functions in manual mode

Answer: (A)

The main idea is that ABS prevents wheel lock during heavy braking, especially on slippery surfaces, so you keep steering control. On a fire apparatus this is crucial because you often need to brake hard in emergencies while still needing to steer around obstacles or hazards. ABS automatically modulates brake pressure to each wheel to avoid skidding, letting you steer where you want to go rather than slide straight ahead.

This system is automatic and active whenever it detects wheel slip; you don’t switch it on or off. It’s designed to work in wet, icy, or uneven conditions, not just in dry weather. It doesn’t aim to reduce brake temperature, and it isn’t about increasing stopping distance on all surfaces—its primary benefit is maintaining control during braking by preventing wheel lock.
