How many times should the headlights alternate between high and low beam in Subject 3?

In Subject 3, the headlights should alternate between high and low beam two or more times, typically three times. Additional information is as follows: Subject 3: Subject 3, which includes the road driving skills test and the safe and civilized driving knowledge test, is a part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safe and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed. Alternating between high and low beam operation: When an oncoming vehicle is within 150 meters, the high beam should be switched to low beam. If the other party does not switch to low beam, immediately reduce speed and continuously alternate between high and low beam to signal. If the other party still does not change, slow down and pull over to the right to yield. Avoid engaging in a battle of bright lights, as it may impair both drivers' vision and lead to an accident.
I just passed the Subject 3 test recently, and I remember clearly that the examiner required us to toggle the high-low beam twice. During practice, I tried it repeatedly - the action is quite simple: first switch to high beam position, then return to low beam position, doing this twice consecutively is sufficient. This operation is commonly used during nighttime encounters with oncoming vehicles - flashing twice to alert opposing traffic and avoid collision risks. The test isn't just about counting the number of toggles; you also need to maintain even rhythm, as doing it too fast or disorderly may result in point deductions. Personally, I think this design is very user-friendly as it reduces mistakes by beginners. After actual driving experience, I've found clear signaling is crucial - one flash less might cause misjudgment by others, while one more would be a waste of energy. That's why it's essential to practice this action thoroughly for the test, simulating it multiple times to ensure accuracy.
Having driven for many years, in the lighting operations of Subject 3, the high-low beam alternation usually requires two or three flashes, but the exam standard is typically two. The purpose is clear: in real driving, flashing the headlights twice is sufficient for signaling, while three times might be excessive or cause false alarms. The test not only evaluates skills but also fosters safety awareness, such as reminding other vehicles in low-light conditions. Operate steadily without haste. I've seen people forget to alternate and just keep the low beams on, which can be dangerous in hazardous areas. It's advisable to practice more during driving lessons and get used to the two-flash action, as it helps with safe driving in the future.
