Which statement indicates a low air brake system pressure warning?

• A. Coolant level alarm
• B. Low pressure warning alarm/light
• C. Oil level alarm
• D. Oil pressure warning light

Answer: (B)

Low air brake system pressure warnings are built to alert you as soon as the air pressure in the brake system drops to a dangerous level. This alert typically shows up as an audible alarm and/or a dash warning light, giving you time to stop safely and address the loss of pressure before the brakes could fail. The other options refer to engine fluids—not the brake system—so they don’t indicate the air brake pressure condition. Thus, the statement about a low pressure warning alarm/light correctly identifies the air brake warning.
