Relates to authorizing a five mile per hour speed limit for open streets in cities having a population in excess of one million

This bill authorizes cities with populations over one million (like New York City) to establish a minimum five-mile-per-hour speed limit on designated "open streets." Open streets are defined as segments with physical barriers, signage, or traffic calming measures that prioritize pedestrians, cyclists, and non-motorized users over vehicles. The bill amends traffic laws to ensure such speed limits comply with existing regulations but does not affect school zone speed limits or simple traffic control signs. It directly impacts urban transportation planning in large cities by mandating the lowest possible speed for these pedestrian-focused zones.
