What are the requirements for converting a blue license plate to a yellow one?

[VanJason]

Blue license plate vehicles cannot be converted to yellow ones. The differences between blue license plate vehicles and yellow license plate vehicles are as follows: Different driver's license requirements: Yellow license plate vehicles require a Class B driver's license to operate, while blue license plate vehicles only need a Class C driver's license. Different toll standards: On highways, blue license plate vehicles have lower toll fees, whereas yellow license plate vehicles generally have higher tolls. Factors such as the size and weight of yellow license plate vehicles contribute to the relatively higher costs. Different annual inspection periods: Yellow license plate vehicles require quarterly inspections, while blue license plate vehicles only need inspections every two years. Different restricted areas: Blue license plate vehicles can drive freely in cities, whereas yellow license plate vehicles are subject to time-based restrictions and require a special permit to operate.
