Bill > HB1027

This bill establishes specific technical requirements for speed control devices (such as speed humps, speed tables, speed cushions, and speed pillows) installed on public roadways in Missouri after August 28, 2025, with the goal of traffic calming. The bill mandates that these traffic-slowing devices must be precisely 14 feet in length and 3.5 inches tall, with the height gradually increasing over two feet on each side of the device. Additionally, the bill requires that these speed control devices be clearly marked to ensure motorists are aware of their presence, which can help prevent sudden, jarring impacts and improve overall road safety. By setting uniform standards for these traffic calming devices, the legislation aims to create more predictable and safer driving conditions in areas where vehicle speed reduction is deemed necessary.
