Who is required to obtain a weigh master license?

To obtain a weigh master license, individuals must be authorized to perform weight measurements for hire. This requirement ensures that those offering weigh services are qualified and are operating within the regulatory framework that governs weight verification. The weigh master plays a crucial role in providing accurate and reliable weight readings, which are essential for various industries, including transportation and logistics.

Having a weigh master license guarantees that the individual has met specific training requirements and adheres to legal standards. This is crucial because incorrect weight measurements can lead to significant discrepancies in charges, legal issues, and even safety concerns on the road.

The other options do not reflect the broader scope of who is required to hold a weigh master license. Not all individuals weighing vehicles on public roads or those conducting internal weight checks must obtain this license, as some may operate under different regulations or exceptions. Additionally, individuals working under direct supervision do not need their own license, as they are typically covered by the supervision of a licensed weigh master. Therefore, the correct answer reflects the necessity for anyone wishing to weigh for hire to be properly licensed to ensure accountability and accuracy in weight measurement.
