Why Can't People with Color Weakness Obtain a Driver's License?
2 Answers
Color weakness can affect a driver's vision, leading to potential dangers while driving. Below is the relevant information for applying for a motor vehicle driver's license: 1. Age requirements: Applicants for small cars, small automatic transmission cars, small automatic transmission passenger cars for the disabled, and light motorcycles must be between 18 and 70 years old. 2. Physical requirements: Height: Applicants for large buses, tractors, city buses, large trucks, and trolleybuses must be at least 155 cm tall. Applicants for medium-sized buses must be at least 150 cm tall; Vision: Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams must have naked or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart.
I've been driving for over ten years, and color recognition in traffic lights is at the core of driving safety. The basic rules—red for stop and green for go—are all conveyed through color. When people with color vision deficiency can't distinguish between red and green, they may make mistakes at intersections, potentially running red lights and causing accidents. The strict medical exams during driver's license tests are designed to prevent these risks. The color differences in traffic signals are meant for quick reaction; failing to distinguish them increases reaction time and errors. In daily life, I've seen many accidents caused by color confusion, so while the regulation is strict, it protects everyone's safety. Friends with color vision deficiency can try other transportation methods first or consult a doctor to see if correction is possible. Understanding that these rules are in place for everyone's safety is truly important.
