In the driver's license classification, Class A permits driving large buses, Class B permits driving large trucks, and Class C permits driving small cars. In 2004, the Ministry of Public Security further subdivided the three types of permitted driving vehicles—Class A (large buses), Class B (large trucks), and Class C (small cars)—based on the driving difficulty and safety requirements of different vehicle types to enhance management precision. 1. Class A is divided into A1, A2, and A3 licenses: A1 corresponds to large buses, A2 to tractors, and A3 to city buses. 2. Class B is divided into B1 and B2 licenses: B1 corresponds to medium-sized buses, and B2 corresponds to large trucks. 3. Class C is divided into C1, C2, C3, C4, and C5 licenses: C1 corresponds to small cars, C2 to small automatic transmission cars, C3 to low-speed trucks, C4 to three-wheeled cars, and C5 to small automatic transmission passenger cars specifically for disabled individuals.

I have been teaching students at the driving school for years to obtain their driver's licenses, and many people often ask what a Class B license is. Simply put, a Class B license is a driving permit for operating large trucks, specifically designed for vehicles exceeding 4.5 tons, such as heavy-duty trucks or large freight trucks. To obtain a Class B license, applicants must be at least 20 years old, pass a physical examination, and have no major illnesses. The test consists of three parts: a theoretical exam on traffic rules, a practical test for maneuvers like reversing into a parking space, and an on-road driving test. Driving such large vehicles is much more challenging than driving smaller cars due to their long bodies, limited visibility, and the need for ample space when turning, which can create blind spots. Holding a Class B license opens up more job opportunities, such as long-haul freight or logistics, but it also comes with greater responsibility, requiring constant attention to safety. It is recommended that beginners first gain experience with smaller vehicles before upgrading to larger ones.

I've been driving trucks for over a decade, and a Class B license is what I hold. It's designed for operating large trucks, typically weighing over 4.5 tons. To obtain a Class B license, you must be at least 20 years old, pass a physical examination, and then succeed in both theoretical and practical tests. Driving large vehicles is quite practical, with high industry demand and good earnings, but you need to master gear-shifting techniques and vehicle maintenance, as big trucks have longer braking distances. Having experienced various road conditions, I advise new applicants to focus on safe driving and traffic rules. The Class B license also includes a B2 subcategory, mainly for freight transport – driving such vehicles requires strong responsibility and no distractions.

From a road safety perspective, a Class B license is the required qualification for operating large trucks. Holders face higher risks when driving heavy vehicles and must pass rigorous examinations. Applicants must be at least 20 years old and pass a pre-test medical examination. The theoretical test covers traffic laws, while the practical test evaluates skills in yard maneuvers and road driving to assess control capabilities. Driving large vehicles involves significant blind spots, necessitating specialized training to prevent accidents. Daily emphasis is placed on speed control and emergency braking.
