Why can't I pass the color weakness test for the 6-year license renewal physical examination?

[VonAna]

For the six-year driver's license renewal physical examination, individuals with color weakness can normally renew their license. According to relevant national laws, only those with red-green color blindness are prohibited from obtaining a driver's license. Here is the relevant information: Generally, if the color weakness is mild and the individual can distinguish between red and green, they can obtain a driver's license. However, if the color weakness is severe, a hospital examination and evaluation are required for a comprehensive assessment to determine eligibility for a driver's license. Color weakness, also known as "anomalous trichromacy," is a color vision deficiency. Individuals with color weakness can recognize colors but have lower sensitivity. They may struggle to distinguish colors unless they are highly saturated and may only detect hue changes when there is a significant difference in wavelength. The "Road Traffic Safety Law" and its implementing regulations stipulate that applicants for a motor vehicle driver's license must meet the prescribed licensing conditions. The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 111) explicitly states that applicants must not have red-green color blindness. Color weakness is not the same as color blindness. As long as the applicant does not have red-green color blindness, they can pass the driver's license physical examination. Those with mild color weakness who can distinguish between red and green can apply for a license renewal, provided they submit a medical examination certificate. The red-green color blindness test during the physical examination aims to prevent traffic accidents caused by running red lights.
