What was the adjustment of the total mass for blue license plates in 2020?

[OCassandra]

In 2020, the total mass for blue license plates was adjusted to a standard of less than 4.5 tons. Although blue license plate trucks are classified as two-axle vehicles in the highway freight vehicle overload and over-limit standards, with a limit of 18 tons, it is important to note the subsequent remark, which states that 'the total mass of the vehicle and cargo for two-axle trucks should also not exceed the total mass indicated on the vehicle registration certificate.' Blue license plate vehicles refer to cars with blue license plates, typically featuring white characters and white borders on a blue background. Penalties for overloading and over-limit violations are as follows: 1. For carrying cargo exceeding 30% or more of the approved load capacity or violating passenger-carrying regulations, a deduction of 6 points will be imposed; 2. For carrying cargo exceeding the approved load capacity but less than 30%, a deduction of 3 points will be imposed.
