3 Answers
Colorblind individuals cannot obtain a driver's license. The following are the physical requirements for applying for a motor vehicle driver's license: 1. Height: Applicants for large buses, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. Applicants for medium-sized buses must be at least 150 cm tall. 2. Vision: For large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or streetcars, the naked or corrected vision in both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other vehicle types, the naked or corrected vision in both eyes must reach 4.9 or above. 3. Color vision: No red-green colorblindness.
I was previously curious about how colorblind people can obtain a driver's license, as a friend of mine faced a similar situation. He told me that the key is being able to recognize the colors of traffic signals, such as red, green, and yellow. Before the driving test, you need to undergo a professional examination at a medical center, where doctors will show you color charts to identify. If you have difficulty distinguishing, some regions allow learning the shapes or positions of the lights as an aid, or even using special filter glasses. Remember, safety comes first—don't push yourself too hard. It's advisable to consult local traffic authorities about the rules in advance, as policies vary slightly by region. I've heard that mild color blindness generally doesn't affect the test, but severe cases may result in failure. In any case, prepare well for the test, choose official channels, and don't believe in unreliable rumors.
I'm often asked about color blindness and driver's license exams, as driving safety heavily relies on vision. Simply put, colorblind individuals must pass a color discrimination test, which isn't overly difficult. During the pre-exam physical check-up, they'll test your ability to distinguish traffic lights; if unsuccessful, you can request a recheck or use visual aids like memorizing light positions. Chinese regulations clearly require the ability to identify signal colors, otherwise the license application will be rejected. I recommend getting assessed by professional institutions and avoiding dubious quick-test services. Note that color recognition becomes even more critical during night driving - regular simulation practice can boost confidence. Ultimately, these rules exist to ensure road safety, and we should approach them with responsible attitudes.
