On behalf of the 400 members of the National Stone, Sand & Gravel Association (NSSGA), I am writing to urge your support for the Truck Parking Safety Improvement Act. This legislation will deliver more effective and safe means of commercial trucking, which is essential to our industry as we maintain our country's vast infrastructure.   NSSGA members consist of stone, sand and gravel producers; industrial sand suppliers; and the equipment manufacturers and service providers who support them. With upwards of 9,000 locations, the aggregates industry produces 2.5 billion tons of materials used annually in the United States. Aggregates are the building blocks of our modern society and are needed to construct and maintain roads, railways, bridges, tunnels, water supply, sewers, electrical grids and telecommunications. NSSGA supports this legislation, as it will increase the desperately needed parking opportunities for our nation’s truckers and attract more drivers to the stretched-thin industry. Our members are prepared to supply the needed construction materials for projects that expand parking, alleviate bottlenecks, improve safety and eliminate congestion on our roads and highways. If passed, this legislation will improve supply chains and keep our strong economy moving.
