A C4D driver's license allows the holder to operate tricycles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles (with an engine displacement exceeding 50ml or a maximum design speed exceeding 50km/h), and light motorcycles (with an engine displacement of 50ml or less and a maximum design speed of 50km/h or less). Upgrading from a C4 to a D license or from a D to a C4 results in a C4D license. The requirements for obtaining a C4D license are: having a C4 license with at least two years of driving experience and meeting the C4 license examination criteria, or holding a D license and applying to add the C4 vehicle category, provided that the applicant has not accumulated 12 penalty points in the current or previous scoring cycle. In other words, one can apply to upgrade to a C4 license one year after obtaining a D license. Eligible applicants should bring their ID card and driver's license to a driving school to apply for the upgrade. A driver's license, officially known as a motor vehicle driver's license or simply "license," is a legal document required by law for individuals operating motor vehicles. It certifies that the holder has learned and mastered traffic regulations and driving skills, passed the relevant administrative examinations, and is legally permitted to operate specific types of motor vehicles. The vehicle categories corresponding to each license class are as follows: C1: Small cars and C2, C3, C4 (passenger vehicles with nine seats or fewer, such as sedans, qualify as small cars); C2: Small automatic transmission cars; C3: Low-speed trucks and C4; C4: Tricycles; C5: Small automatic transmission passenger cars for disabled individuals (specifically those with right lower limb disabilities, both lower limb disabilities, hearing impairments, missing right thumbs, or finger amputations); D: Ordinary three-wheeled motorcycles; other permitted vehicle categories: E, F; E: Ordinary two-wheeled motorcycles and F; F: Light motorcycles. A D license permits the operation of the following vehicle types: Electric light motorcycles: These are electric vehicles with a speed limit of 50km/h, typically equipped with 60V20AH/32AH batteries. They are among the most popular electric vehicle models besides standard electric bikes and require a blue license plate. After obtaining a D license, they can be driven legally. Note: These electric light motorcycles are prohibited from carrying passengers, and many cities penalize such violations with fines. Electric motorcycles: These are electric vehicles exceeding 50km/h, usually equipped with high-power motors and large-capacity batteries, resulting in high speed and strong power. They pose certain safety risks and require a yellow license plate. A D license allows their operation. Note: These electric motorcycles cannot be driven in cities where motorcycles are banned. Violators may have their vehicles impounded. Leisure tricycles: These tricycles have a speed range of 25-35km/h, stable chassis, and spacious seating, making them popular among seniors and parents. They require a blue license plate and can be driven with a D license. Note: While many cities do not explicitly prohibit passengers, local regulations should be checked to avoid fines. Enclosed tricycles: These tricycles, with speeds of 35-45km/h, offer full-body coverage for weather protection and comfort. They require a yellow license plate and can be driven with a D license. Note: These vehicles can carry passengers but only for personal use. Commercial use is prohibited and may result in fines or impoundment. Cargo tricycles: Designed for speeds around 45km/h and high load capacity (typically over 1500 pounds), these tricycles require a yellow license plate and can be operated with a D license. Note: Carrying passengers is strictly prohibited due to significant safety hazards. Violations may result in fines of 500-1000 RMB and vehicle impoundment.
