Who must report to the weigh scale when the amber lights are flashing?

When the amber lights are flashing at a weigh scale, all commercial vehicles, including trucks and buses, must report to the scale. This typically includes vehicles that are required to weigh in for compliance with weight regulations or safety checks. Additionally, any vehicles carrying hazardous materials or oversized loads may also be required to stop. It's important for drivers to adhere to these signals to ensure road safety and regulatory compliance.
