What is the reason for failing the alternating high-low beam test in Subject 3?

[NatalieLee]

Failing the alternating high-low beam test in Subject 3 is due to operating the flashing lights too quickly. Below are specific details about the alternating high-low beam test in Subject 3: 1. Precautions: When the driving test voice system announces overtaking or when there are no traffic signals, you can alternately use the high and low beams. You must turn on the corresponding lights within 5 seconds after the system finishes the announcement, neither answering too early nor delaying. 2. Instructions: During the lighting test, alternate between high and low beams when you hear voice prompts such as approaching a sharp curve, approaching a slope, approaching a humpback bridge, approaching a crosswalk, or approaching an intersection without traffic signal control. You must alternate the high and low beams at least twice.

I recently stumbled on the high-low beam switching during my driving test (Subject 3). The reason was clear: when the examiner gave the instruction to alternate between high and low beams over a certain distance, I got too nervous and pressed the wrong switch. I hadn't practiced enough beforehand, so during the test I was flustered—either switching too early or forgetting to reset the lights. Another issue was that the car's light switch was old and had a slight delay of a fraction of a second, which led to a failing mark. My advice is to practice more in the instructor's car to simulate real test conditions, get familiar with the switch positions, and take deep breaths to relax before the test to minimize mistakes. Failing the test wastes time and means starting over, so take this step seriously—don't treat it as a minor detail.

As a driving instructor with years of experience training students, I've seen many fail the third driving test due to the high-low beam switching segment. The main reason is insufficient mastery of the light operation sequence. The test requires immediate light switching upon hearing the instruction, but students often react too slowly or switch too quickly, resulting in errors when the lights haven't stabilized. Another pitfall is unfamiliarity with switch positions, which can be confusing when test vehicles differ. I recommend dedicating 10 minutes daily during practice specifically for light exercises, including simulated night driving scenarios. This builds muscle memory, preventing panic during the test and significantly increasing passing rates. Remember, small details determine success—don't neglect light operations.

When I first started learning to drive, I failed the high-low beam switching part of the third subject a few times. The biggest problem was that I couldn't remember where the light switch was, and my hands would shake nervously during the test, making the light switching action unsteady. The instructor pointed out that I switched too fast or too slow, not meeting the test's rhythm requirements. Another difficulty was that the car lights were a bit sluggish, sometimes making the switching inaccurate. Later, I practiced night driving more times to familiarize myself with the switch position and operation feel, and finally got it right. This step seems simple, but it actually tests your mindset and basic skills. Practicing more mock tests before the exam and accumulating experience will help.
