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

[XavierAnn]

For the six-year license renewal physical examination, color weakness does not prevent normal renewal. According to relevant national laws, only those with red-green color blindness are not allowed to obtain a driver's license. Here are the relevant details: Generally, if the color weakness is mild and the person can distinguish between red and green, they can obtain a driver's license. However, if the color weakness is very 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. Those with color weakness can recognize colors but have lower sensitivity. They have difficulty distinguishing colors and can only see them when the colors are highly saturated; they can only differentiate 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) clearly states that applicants must have no red-green color blindness in their color vision. Color weakness is not color blindness. As long as the applicant does not have red-green color blindness, they can pass the driver's license physical examination. Mild color weakness that allows the distinction between red and green permits the renewal of a driver's license, provided a hospital's physical examination certificate is submitted. The red-green color blindness test during the physical examination is intended to prevent traffic accidents caused by running red lights.
