2.3.1. When designing, the location of the scale must be selected based on the terrain and actual traffic conditions on the route; it should be arranged on national roads, expressways, traffic gateways, origins of goods, toll stations, connecting branches to expressways, and positions before entering expressways according to actual traffic conditions.

2.3.2. Measures to prevent overloaded vehicles from entering expressways (arranging bypass lanes for violator vehicles to exit the expressway, arranging camera systems to monitor violator vehicles exiting the expressway); it may also control vehicles traveling on roads and prevent controlled-load vehicles from avoiding the weighing zone.

2.3.3. Measures to ensure traffic safety, maintain distance between vehicles to ensure that only one vehicle can enter each lane in the weighing zone to avoid license plates being obscured or measurement errors caused by overlapping vehicles.

2.3.4. The automatic weighing equipment can automatically check the operational status of each weighing sensor (sensor), detect the exact position of faulty weighing sensors (if any).

2.3.5. The data processing software system must have the function of automatically generating, sending, and storing reports through the software of the vehicle weight control works' weighing equipment and camera systems.

2.3.6. For vehicle weight control works located in toll station areas or areas where infrastructure and equipment (concrete roads, various types of cameras, RFID reading devices, traffic signs, gantries, and auxiliary equipment) have been invested and built, they must be designed to maximize the shared use of these infrastructures and equipment.

2.3.7. Illustrative diagram of vehicle weight control works in Appendix A of this regulation.

2.4. Technical process design requirements for vehicle weight control works.

2.4.1. Before and within the weighing zone, a traffic signal system must be designed to ensure vehicles travel at permitted speeds, maintain safe distances, change lanes according to traffic signs and markings, and not stop or park illegally.

2.4.2. In the weighing zone, the dynamic weighing system must be designed to automatically measure (weigh) the mass of each axle of the vehicle wheels, recognize the license plate number, determine certain technical parameters of the vehicle (type of vehicle, total number of axles, axle structure, axle spacing, self-weight of the vehicle (including cars, semi-trailers, trailers), permitted total passenger weight on the vehicle, permitted towing weight of the vehicle, permitted cargo weight for traffic participation of the vehicle), record cases where vehicles show signs of violating traffic rules, store and transmit data to the data processing software.

2.4.3. After the weighing zone, a VMS sign, camera, warning system including red rotating lights and alarm sirens, directional arrow signs guiding the direction of vehicle movement or KSTTX construction staff (if available) must be arranged to guide vehicles to continue moving or follow the lane to exit the highway or enter the processing area (if available) if overloaded.

2.4.4. The design must ensure the detection and collection of images and data as a basis for handling situations when the vehicle driver does not comply with KSTTX through the following forms:

2.4.4.1. Covering the license plate so that the license plate recognition device cannot read the license plate number;

2.4.4.2. Covering or dirtying or making dirty or bending part of the license plate or actions causing the recognition system to make errors or incomplete or excess characters of the license plate number;

2.4.4.3. Driving off-lane or driving at a speed faster or slower than the prescribed speed at the KSTTX construction site;

2.4.4.4. Driving in close proximity to avoid the angle of view of the license plate recognition system, causing errors in the weighing results of the vehicle load.

2.5. Requirements for Infrastructure Structure of Weigh Station Engineering Works
