Stop lamps should not have what on the lenses?

Stop lamps are crucial safety components on vehicles, designed to alert drivers behind when a vehicle is slowing down or coming to a stop. To ensure maximum visibility and effectiveness, the lenses of stop lamps should be clear and unobstructed.

Tinted lenses, whether they are slightly darkened or colored, can interfere with the brightness and clarity of the signal emitted. This can lead to dangerous situations, as other drivers may not see the stop lamps clearly, delaying their reaction time. Similarly, colored lenses that deviate from standard red fail to meet safety regulations since stop lamps must emit a red light to clearly indicate the intention to stop.

Painted lenses pose the same issues; the paint can diminish the light's brightness or alter its color, rendering the stop lamp ineffective at signaling to other drivers. Consequently, all types of alterations that impede the performance of stop lamps fall under the category of items that should not be present on the lenses, solidifying the answer as accurate. Maintaining clear, unaltered lenses ensures that the stop lamps function as intended, thereby enhancing overall roadway safety.
