What must be permanently marked on each side of trailers for predetermined individual trailer tare weights?

Each trailer must have its predetermined tare weight permanently marked on each side for several important reasons. Tare weight represents the weight of the empty trailer, which is crucial for understanding how much weight can be safely loaded onto it. Properly marking the tare weight fosters compliance with regulations to ensure safety standards are met when the trailer is used for hauling loads. By having this information readily visible, operators can quickly ascertain the trailer's weight capacity, helping prevent overloading situations that could lead to accidents or legal issues.

In contrast, while the company code, serial number, and license number serve various identification and tracking purposes, they do not provide immediate information regarding the weight capacity of the trailer itself. Therefore, the marking of predetermined tare weight is essential for operational safety and regulatory compliance.
