How many times should the high and low beams be alternated in Subject 3?

No less than two times. Below is a related introduction to Subject 3: Introduction: Subject 3, including the road driving skills test and the safe and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skills and safe and civilized driving knowledge test subjects in the motor vehicle driver's test. Test Content: The road driving skills test for Subject 3 includes large buses, tractors, city buses, medium-sized buses, large trucks, small cars, small automatic transmission cars, low-speed cargo trucks, and small automatic transmission passenger cars for the disabled, among others.
I just passed the Subject 3 test and have strong feelings about the lighting operation part. The high-low beam alternation usually requires two quick switches. For example, when you hear voice prompts like 'oncoming vehicle' or 'overtaking,' you need to quickly pull the control lever twice to simulate the action of alerting other vehicles in real situations. During my practice, I often made mistakes due to nervousness—either switching too fast for the examiner to recognize or forgetting the second switch, which resulted in a retake. The lighting test is a mandatory item in the exam with many points to lose, so I recommend practicing more on the simulator at the driving school to get familiar with the rhythm. Besides alternation, the lighting section also includes fog lights and hazard lights operation. Mastering all of them can improve your pass rate. In actual driving, correct lighting operation can prevent nighttime accidents, and forming this habit is crucial. Now, I always remember this standard action during night drives, making it much safer. In short, remembering the two quick switches is key—stay calm during the exam and follow the instructions.
As someone quite interested in automotive knowledge, I've carefully studied the content of the lighting test for Subject 3. The alternating between high and low beams requires two operations, which is an official standard designed to simulate real driving scenarios, such as giving clear signals when overtaking or meeting another vehicle. Technically, pulling the control lever twice represents completing one full cycle: first switching to high beam and then back to low beam once, then repeating it again to ensure the lighting system responds accurately. During the test, voice prompts will give instructions, and the examiner will check the coordination of the movements to avoid being too fast to pass or too slow to miss. I recommend watching more test videos to learn the correct technique, as lack of proficiency in lighting operations increases the risk of failure. In practice, this standardized training can reduce misunderstandings, improve road safety, and be very helpful for beginners.
