What is the minimum visibility distance for a stoplight on trailers with a gross weight over 3,000 pounds?

The minimum visibility distance for a stoplight on trailers with a gross weight over 3,000 pounds is correctly set at 100 feet. This standard is established to ensure that other drivers have adequate time to react when they encounter a trailer making a stop or adjusting its speed. The 100-foot requirement is designed to enhance overall road safety by providing sufficient visibility, especially in traffic situations where larger vehicles are present.

This distance is crucial because it helps prevent accidents that may occur due to a lack of awareness of slower or stopping vehicles, particularly on highways or busy roads where speed differentials can be significant. Ensuring that stoplights are visible from 100 feet away allows for a better flow of traffic and helps to avoid sudden stops or collisions.
