Here are the differences between C1, C2, C3, C4, and C5 driver's licenses: 1. Permitted vehicle types for C1: Small cars; other vehicle types permitted by C2, C3, and C4. 2. Permitted vehicle types for C2: Small automatic transmission cars. 3. Permitted vehicle types for C3: Low-speed trucks and C4. 4. Permitted vehicle types for C4: Three-wheeled cars. 5. Permitted vehicle types for C5: Small automatic transmission passenger cars specially designed for disabled people (referring to five categories of people: those with disabilities in the right lower limb, both lower limbs, hearing impairment, missing right thumb, or missing finger end joints).

When I first got my driver's license, I also couldn't figure out these letter-number combinations, but I understood them better after working in transportation. C1 is the most common one—it allows you to drive both manual and automatic small cars, as well as light vans with fewer than 9 seats, as long as the vehicle weight doesn’t exceed 4.5 tons. C2 is simpler, only permitting automatic transmission cars, and many beginners nowadays opt for this since the test is easier than C1. C3 is actually for cargo transport, allowing low-speed trucks and agricultural tricycles, like tractor heads with a max speed under 70 km/h. C4 is even more niche, specifically for three-wheeled cars—steering wheel-style trikes. The most unique is C5, designed for people with disabilities, requiring modified automatic vehicles with assistive devices.

Before taking the driving test, I specifically checked: The Class C license system is actually categorized by vehicle type. C1 is the most comprehensive, allowing you to drive both sedans and small trucks, but be mindful that the vehicle length should not exceed 6 meters. C2 is restricted to automatic transmission vehicles, but nowadays, automatic cars are everywhere, so it's generally sufficient. C3 is rarely used in practice these days, mainly for low-speed trucks with engine displacements below 1.5 liters. Three-wheeled vehicles require a separate C4 license, which is different from the regular three-wheeled motorcycle license (Class D). As for C5, I've seen friends drive modified vehicles with the accelerator and brake controls on the steering wheel—this type requires a medical certificate to take the test.

Explain these driver's licenses in three points: In terms of permitted vehicle types, C1 covers small cars (including manual/automatic) and light trucks; C2 is limited to automatic transmission small cars; C3 permits low-speed trucks; C4 for three-wheeled vehicles; C5 is specially designed automatic transmission vehicles for disabled individuals. Regarding exam difficulty, C1 is the most challenging with hill-start testing, while C2 eliminates the hill-start requirement. The target groups also differ: C2 suffices for daily commuting, C1 or C3 for freight transport, and C5 for those with physical disabilities. Notably, driving an unpermitted vehicle type counts as unlicensed driving—for example, using a C2 license to operate a manual transmission car results in an immediate 9-point deduction.
