Difficulty: MediumNight Driving and Headlight Glare Management

When traveling on a highway at night, a driver experiences intense glare in their interior rearview mirror caused by the bright headlights of a trailing vehicle. Which action should the driver take to safely minimize this glare?

  1. Shift the interior rearview mirror to its night position or day/night setting.Answer
  2. B
    Turn on the interior cabin dome light to equalize the brightness inside the vehicle.
  3. C
    Accelerate significantly above the posted speed limit to quickly outdistance the trailing vehicle.
  4. D
    Adjust the exterior side mirrors outward to bounce the high beams back at the trailing vehicle.

Answer

Shift the interior rearview mirror to its night position or day/night setting.
Adjusting the interior rearview mirror to its night setting (or using the anti-glare tab) reduces the intensity of light reflected into the driver's eyes from trailing headlights while allowing the driver to maintain situational awareness.

Step-by-Step Solution

1
Identify the primary source of vision impairment
Reflected headlight glare from behind entering through the interior rearview mirror.
Bright headlights from trailing vehicles reflect directly into the driver's eyes.
2
Select the appropriate vehicle safety control designed for rear glare management
Engage the day/night tab at the base of the manual interior mirror (or rely on auto-dimming function).
This adjustment tilts the mirror glass to reduce reflected light intensity without altering the driver's speed or forward field of vision.
