After completing the simulated lighting test in Subject 3, there is no need to switch from high beam to low beam before turning off the lights. You can turn off the lights directly. The relevant explanation is as follows: Subject 3 lighting simulation test items: When turning at an intersection at night, use low beam. When driving on roads with low visibility at night, turn on high beam. When approaching sharp curves at night, alternate between high and low beams no less than 2 times. When approaching slopes at night, alternate between high and low beams no less than 2 times. Additional note: When driving at night without street lights, poor illumination, or encountering low visibility conditions such as fog, rain, snow, dust, or hail, the vehicle should turn on headlights, position lights, and rear lights. However, high beam should not be used when following another vehicle closely in the same direction.

As a driving instructor who frequently accompanies students for their license tests, I've observed that the high beam operation during the Section 3 lighting simulation has strict procedures. After completing the high beam test, you must manually switch back to the low beam position before turning off the main switch. This process isn't redundant—it's designed to simulate real driving safety. Turning off the lights directly might cause the strong light to disappear instantly, leading to temporary eye discomfort, and the examiner may deduct points for perceived lack of safety awareness. I recommend that beginners pay extra attention to this sequence during practice: first complete the high beam observation, gently turn the lever to the low beam position, confirm, and then turn off the main switch. Developing this habit can also prevent nighttime accidents in daily driving. Remember to simulate this process several times before the test to ensure smooth, error-free operation. The test evaluates not just technical skills but also attention to safety details.

Last year when I took the Category 3 driving test, I also wondered about this issue. The driving instructor repeatedly emphasized that after turning on the high beams, you cannot turn them off directly. You must first switch back to low beams before turning off the entire lighting system. This is because in simulated scenarios, avoiding sudden light changes prevents examiners from misjudging it as unprofessional operation. In real driving, directly turning off high beams may cause visual interference for vehicles in front and behind, increasing risks. During practice, I often forgot this step and was criticized multiple times as a result. Later, it became a habit - after using high beams, I always switch to low beam position first before turning them off. During the test, the examiner did check this detail, and many candidates lost points because of it. I recommend reviewing lighting operation standards more to ensure a smooth test.

From the perspective of vehicle lighting system operation principles, the requirement to switch back to low beam before turning off the high beam during the Category 3 simulated lighting test is a technical necessity. If high beams are turned off directly, the sudden disappearance of intense light affects visual adaptation time. Demonstrating the switching procedure in operation reflects safety control capabilities. Examiners pay attention to this sequence during actual tests to evaluate standardized awareness. During operation, first activate high beams for inspection, then manually return the lever to the low beam position before turning off the master switch. Developing this habit in daily driving can also reduce potential accidents. Practice the feel of the lighting lever positions frequently, familiarize yourself with the vehicle interface, and improve test scores.
