What is the rejection criteria for headlight measurements?

The rejection criteria for headlight measurements specifically indicates that headlights must be positioned within a certain height range from the surface of the road. According to the regulations, headlights that fall below 22 inches or exceed 54 inches in height are deemed non-compliant. This is important because proper headlight height ensures adequate illumination of the roadway without causing glare for other drivers.

Headlights that are too low may not adequately illuminate the road ahead, presenting dangers during nighttime driving or in poor visibility conditions. Conversely, headlights that are too high could illuminate the eyes of oncoming drivers, leading to increased risk of accidents. This regulation aims to promote safety for all road users by ensuring that headlights are set at optimal levels.

The other options related to headlight measurements do not align with these established standards, thus affirming the significance of the correct choice regarding rejection criteria for headlight measurements.
