Circumstances under which you cannot apply for a motor vehicle driver's license are as follows: 1. Suffering from organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, paralysis agitans, mental illness, dementia, or neurological diseases affecting limb movement that hinder safe driving; 2. Addiction to or injection of narcotics or long-term use of dependency-inducing psychotropic drugs without successful withdrawal; 3. Revocation of the motor vehicle driver's license for less than two years; 4. Fleeing the scene after causing a traffic accident, resulting in the revocation of the motor vehicle driver's license; 5. Revocation of the driving permit by law for less than three years. Below are the relevant requirements for obtaining a 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: Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. Applicants for other vehicle types must have uncorrected or corrected visual acuity of at least 4.9 on the logarithmic visual acuity chart. 3. Color Vision: No red-green color blindness (color weakness is not equivalent to color blindness, and there are degrees and color distinctions, so there are no restrictions based on the regulations themselves). 4. Hearing: Ability to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork. Those with hearing impairments who can meet the above conditions with hearing aids may apply for a motor vehicle driver's license for small cars or small automatic transmission vehicles. 5. Age: The age requirement for applying for a small car (Class C) or a light motorcycle is between 18 and 70 years old, while for Class A or Class B licenses, the maximum application age is under 50 years old.

When I was getting my driver's license, I learned that there are some situations where you simply can't apply. The most basic one is being under 18 years old—too young, you have to wait. Another key point is poor eyesight, like not being able to see things clearly in the distance, or severe color blindness that makes it hard to distinguish traffic light colors—driving like that is too dangerous. Physical disabilities are another factor, such as having a hand or foot impairment that affects operating the steering wheel or pedals—you must be healthy to drive. If you have a mental illness or intellectual disability and a doctor determines it’s unsafe after an examination, you can't apply. Additionally, if you've committed offenses like drunk driving or drug use and are still within the penalty period, the system will have you on a blacklist. Lastly, if you already have a license that’s been revoked and the issue hasn’t been resolved, don’t even think about applying for a new one. In short, these rules are all for road safety, to avoid harming yourself and others.

Not everyone can successfully apply for a driver's license, as certain health conditions can lead to immediate disqualification. From my own observation, poor vision like severe myopia without correction is unacceptable; failing the color blindness test is another obstacle. More serious conditions like frequent epileptic seizures, if not well-controlled, will also prevent approval. For mental health, conditions such as depression or dementia require a doctor's certification of stability. Additionally, unaddressed alcoholism or a record of drug abuse will make the application impossible. These restrictions aren't arbitrary—they're in place to prevent accidents, as no one wants to encounter a driver who suddenly has a medical episode on the road. It's wise to undergo thorough medical checks beforehand to avoid wasting money on a doomed application.

I've heard friends talk about driver's license matters before, and there are several situations where you can't apply. Being under 18 years old is the basic restriction. Health-wise, for example, if you're colorblind and can't distinguish traffic lights, you'll be directly rejected. Physical disabilities like having difficulty operating equipment with your hands also pose obstacles. Additionally, you can't apply if you have untreated mental illness. Importantly, if you've had issues with alcohol or drugs, leaving a stain in your records, you're disqualified. Also, don't bother trying if you're serving a prison sentence or during the period when your previous license was revoked. In summary, health and safety checks are strict to avoid causing trouble.
