Which action helps minimize glare and maintain visibility at night by adjusting interior lighting?

• A. Increase the brightness of the dome light.
• B. Dim the brightness of your instrument panel.
• C. Turn on the radio to drown out glare.
• D. Open the windows.

Answer: (B)

Keeping interior lighting low at night helps your eyes stay adapted to darkness and reduces reflections that can wash out what you see outside. The instrument panel emits light that can bounce around inside the cab and create glare on the windshield, especially when outside is dim. Dimming the instrument panel lowers that internal glow, preserving night vision and making it easier to detect hazards like pedestrians, signs, or animals on the road. The other options either add light inside the cab or don’t address the glare issue—turning on the radio won’t change lighting glare, opening windows doesn’t reduce interior reflections, and increasing the dome light actually increases glare. So, dimming the instrument panel brightness is the best choice for maintaining visibility at night.
