The age requirement for applying for an A1 driver's license is between 26 and 50 years old. Other requirements are as follows: Height must be at least 155 cm; visual acuity must be at least 5.0 on the logarithmic visual acuity chart (either naked or corrected vision); no red-green color blindness; ability to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork; both thumbs must be intact, and each hand must have at least three other fingers intact with normal movement function; both lower limbs must be intact with normal movement function, with a length difference not exceeding 5 cm and no movement dysfunction. An A1 driver's license can only be obtained through license upgrading and cannot be applied for initially like a C1 or B2 license. The most common path is to start with a C1 license, then upgrade to an A3, B1, or B2 license before upgrading to an A1 license. Applicants must have held an A3, B1, or B2 license for at least five years and must not have accumulated 12 penalty points in the current scoring cycle or the last five consecutive scoring cycles to upgrade to an A1 license. For those upgrading from an A2 license to an A1 license, the requirements are: having held the A2 license for at least two years and not having accumulated 12 penalty points in the previous scoring cycle. According to Article 12 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," applicants must meet the following requirements: For small cars, small automatic transmission cars, small automatic transmission cars for the disabled, and light motorcycles, the age requirement is between 18 and 70 years old.

For city buses, large trucks, trolleybuses, or trams, the age requirement is between 20 and 50 years old. For medium-sized buses, the age requirement is between 21 and 50 years old.
