To operate a concrete mixer truck, a B2 driver's license is required. It can be obtained directly as a beginner's license, but the applicant must be at least 21 years old and must apply in their permanent residence (place of household registration). Additional information is as follows: Driver's License: A motor vehicle driver's license is a legal document issued by the administrative authorities after a person who is legally permitted to learn to drive a motor vehicle has studied, mastered traffic regulations and driving skills, and passed the relevant examinations. It certifies the holder's qualification to drive a specific type of motor vehicle. B2 Driver's License: A B2 license allows the holder to drive heavy and medium-duty trucks or large, heavy, and medium-sized specialized operation vehicles. Heavy and medium-duty trucks are primarily trucks.

I've been in construction site transportation for ten years, and driving a concrete mixer truck requires carrying two certificates to feel secure. The most basic one is a B2 driver's license, but in practice, companies usually require an A2 license for added safety. Here's the key point: having just a driver's license isn't enough—you also need to obtain a concrete mixer truck operation certificate, which is a special equipment operation permit. Without it, you can't even start the vehicle. Before starting work, you also need to get a freight transport qualification certificate, which requires annual continuing education hours. Remember to bring both paper and electronic copies, as construction sites check certificates more strictly than traffic police. Last month, our team member Xiao Wang forgot his operation certificate and was penalized with a three-day work suspension. In our line of work, you must keep a close eye on whether your certificates are expired—falling steel bars and concrete are no small matter.

New drivers who just got their concrete mixer truck license share their experience. First, obtain a B2 driver's license, and pay extra attention to practicing reversing with the mixer drum during the second test. Then comes the core certification: the Special Equipment Operator License issued by the Quality Supervision Bureau (select mobile crane operation as the project), which requires on-site testing of drum rotation and emergency braking. Don't forget to apply for the Road Transport Practitioner Qualification Certificate, and book the theory test on the transportation bureau's website. Actually, the hardest part isn't the tests but controlling the drum rotation speed—too fast and the concrete segregates, too slow and it solidifies. During practice, experienced drivers taught me to judge the rotation speed by listening to the drum's sound. It's recommended to use a document holder to organize all materials, saving time during worksite inspections.

The certification requirements for operating a concrete mixer truck are more complex than those for a regular truck. Holding an A2 or B2 driver's license is a prerequisite for driving on the road. The key is obtaining the 'Special Equipment Operator Certificate.' When I took the exam, it covered the principles of loading balance for the tank and emergency handling. Those who have retaken the exam know that calculating the balance coefficient is the most challenging part. Additionally, a freight transport qualification certificate is required, and it's advisable to directly qualify for the hazardous materials transport category, which allows you to transport asphalt in the future. Construction sites also require a Three-Level Safety Education Card, which companies provide training for during onboarding. A reminder to everyone: certifications need to be reviewed every four years. Last year, I had to retake my operation certificate after it expired, costing me 800 yuan. Emergency braking in a tanker truck can easily cause solidification, so I make it a habit to check the brakes before every trip.
