How many times should the high and low beams be alternated in Subject 3?
2 Answers
No less than twice. More information about alternating high and low beams in Subject 3 is as follows: Overview: During the lighting test, 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 lights,' you should alternate between high and low beams no less than twice. Other instructions: When you hear 'Prepare to overtake, please use the correct lights,' first turn on the left turn signal, then alternate between high and low beams no less than twice, and finally turn on the right turn signal. After completing the lighting simulation, the candidate must turn off the lights before proceeding to the next test item.
I remember during the Category 3 lighting test, the examiner particularly emphasized the simulated operation of light switching. The most common scenario is simulating an overtaking signal, which requires alternating between high and low beams twice: first, switch to high beam by pulling the light lever, then back to low beam, and repeat the same operation once more, totaling two alternations. This is not only a test requirement but also a crucial skill for ensuring safety in actual driving. For instance, when overtaking at night, alternating lights can effectively alert the vehicle ahead, preventing rear-end collisions. I recommend practicing this maneuver frequently during driving lessons—find an open area to repeat the operation and develop muscle memory. Mastering light usage makes night driving much steadier. Pay attention to speed control in the details; avoid jerking the steering wheel during switches to keep the vehicle stable. Once mastered, the test becomes easier, and you can apply this skill in everyday driving.
