What is the visibility requirement for stop lamps on a vehicle?

The visibility requirement for stop lamps on a vehicle is typically set at 300 feet away. This standard ensures that other drivers have sufficient time to react when a vehicle is stopping. By having stop lamps visible from this distance, it promotes safety on the roads, allowing for clear communication of a driver's intention to slow down or stop. The 300-foot visibility requirement helps maintain safe driving distances, particularly in varying traffic conditions, which is essential for preventing accidents. Therefore, this distance serves as a critical guideline that vehicles must meet to enhance overall road safety.
