What practice reduces nighttime glare for drivers during training?

• A. Increase dashboard brightness to max
• B. Minimize bright lights in driver's line of sight
• C. Leave interior lights on full
• D. Use only external lighting

Answer: (B)

Preserving the driver’s night vision is the key idea here. When it’s dark outside, the eyes adapt to low light, and bright interior lights can cause glare and afterimages that wash out the outside scene. Keeping interior lighting dim or off reduces that glare in the driver’s line of sight, helping them detect hazards, pedestrians, and road edges more clearly. If some illumination is necessary for readability of controls, use only the minimum level and prefer low-intensity, red lighting so it doesn’t disrupt night adaptation.
