In general, you need to bring your driver's license to the traffic management office where it was issued and visit the violation handling window to ask the police to help you check the reason why your driver's license was "locked." After taking the corresponding measures, it can be "unlocked." If the reason is related to health conditions, then the driver's license can only be unlocked once the physical conditions meet the requirements. The following situations may result in a locked driver's license: 1. Suffering from organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, paralysis agitans, mental illness, dementia, or other neurological diseases that affect limb movement and hinder safe driving; 2. Having used or injected narcotics within the past three years or having been released from compulsory isolation for drug rehabilitation for less than three years, or being addicted to dependency-inducing psychotropic drugs and not yet having quit; 3. Committing a hit-and-run that constitutes a crime; 4. Causing a major traffic accident while driving under the influence of alcohol or drunk driving, which constitutes a crime; 5. Having the driver's license revoked for drunk driving or driving a commercial vehicle under the influence of alcohol, and less than five years have passed; 6. Having the driver's license revoked for drunk driving a commercial vehicle, and less than ten years have passed; 7. Having the driver's license revoked for other reasons, and less than two years have passed; 8. Having the driving permit revoked, and less than three years have passed; 9. Other circumstances stipulated by laws and administrative regulations.
