A stop lamp must be visible from a distance of not less than how many feet to the rear in normal sunlight?

A stop lamp must be visible from a distance of not less than 300 feet to the rear in normal sunlight. This requirement is essential for safety on the road, ensuring that drivers behind a vehicle can clearly see when the vehicle is stopping or slowing down. The visibility distance enhances awareness and helps prevent rear-end collisions, as it provides ample time for following drivers to react to the brake lights.

The standard of 300 feet is established to ensure that the stop lamp can be seen at a distance where a reasonable response can be executed. This distance is also reflective of typical road conditions and speeds, which makes it an important safety regulation. In practical terms, it means that if a vehicle suddenly decelerates or stops, another driver should have enough time and distance to respond accordingly, promoting overall road safety.
