In Subject 3, use low beam when meeting vehicles at night, switch to high beam when the oncoming vehicle is more than 150 meters away, and use low beam when meeting non-motor vehicles on narrow roads or bridges. Subject 3 is part of the motor vehicle driver's license assessment, short for the road driving skills and safe civilized driving knowledge test. The road driving skills test generally includes: preparation before driving, light simulation test, starting, driving straight, gear shifting operation, lane changing, pulling over, going straight through intersections, turning at intersections, meeting vehicles, overtaking, making U-turns, night driving, etc. The test content varies for different types of vehicles. The safe civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, and knowledge of handling after traffic accidents.

I remember when I was preparing for the Driving Test Part 3, my instructor kept emphasizing that I must switch to low beams when encountering vehicles at night, never use high beams, as it could dazzle oncoming drivers and cause accidents. During the actual test, forgetting to switch lights would result in major point deductions or even failure. I was so nervous back then that I made several mistakes during practice. Eventually, I developed a habit of switching to low beams as soon as I spotted headlights from afar. Now, when driving on the road, I still stick to this practice—safety first, especially when meeting vehicles on mountain roads or narrow lanes with poor visibility. It's crucial to simulate night scenarios during regular practice to get familiar with light switching. After all, Part 3 tests both safety awareness and practical skills—don't let small mistakes ruin all your hard work.

Having driven for many years, I believe using low beams during nighttime encounters is a fundamental safety rule. The intense glare from high beams makes it hard for the other driver to see the road, greatly increasing collision risks. I once nearly had an accident simply because I forgot to switch beams. During the Subject 3 driving test, examiners particularly emphasize this point as it directly reflects a driver's sense of responsibility. In the test, you must switch to low beams dozens of meters in advance - just flick the control lever typically located below the left side of the steering wheel. The same applies to regular driving: develop a conditioned reflex to switch beams upon seeing opposing headlights, ensuring safe visibility for both parties. This isn't just a rule, but a practical risk-avoidance technique.

When meeting another vehicle at night, you should use low beams and act quickly and accurately: as soon as you see the headlights of the oncoming vehicle, immediately switch from high beams to low beams using the light control lever. This detail is a key point in the test, and the examiner will check whether it is completed promptly and correctly. You should switch the lights at a distance of about 100 meters, maintaining a low profile of light to avoid disturbing the other party. During regular practice, familiarize yourself with the vehicle's lighting system, and go through the process several times before the test to ensure a smooth pass in this part of Subject 3.
