What is the Mnemonic for Light Operation?
2 Answers
The mnemonic for light operation is as follows: Low beam operations are numerous, specifically including: Narrow bridges or roads with oncoming traffic, straight through intersections with streetlights; Following another vehicle closely in the same direction, driving under good lighting conditions. High beams should be used sparingly and cautiously, only when there is poor lighting and no streetlights. Pay attention to alternating between high and low beams, switching lights at night: Sharp curves, slopes, and arch bridges, overtaking and passing pedestrian crossings; Intersections without traffic lights, flashing high and low beams to alert pedestrians and vehicles. There are also three special situations where you must remember to turn on the hazard lights: Driving in fog with fog lights, parking due to a fault with position lights. Correct methods and timing for using lights: Night driving: Alternate between high and low beams. Driving in fog: Turn on the width marker lights, front and rear fog lights, and hazard lights. In case of a breakdown: Turn off the headlights and turn on the width marker lights and hazard lights. Correctly turning on lights when driving at night. Correctly use low beams when following another vehicle closely in the same direction. When passing sharp curves, slopes, arch bridges, pedestrian crossings, or intersections without traffic lights, correctly alternate between high and low beams to signal. When meeting another vehicle, correctly switch to low beams when the oncoming vehicle is more than 150 meters away. Correctly use low beams when turning at intersections. When overtaking, correctly alternate between high and low beams to alert the vehicle being overtaken. Correctly use low beams when driving on well-lit roads with streetlights. Correctly use high beams when driving on unlit roads at speeds exceeding 30 kilometers per hour. Correctly use lights when driving in low visibility conditions such as fog, rain, or snow.
I remember when I first started driving, an experienced driver taught me a rhyme for light operation: 'Keep low beams on, limit high beams, use yellow lights in fog.' This means that during the day, you generally use the parking lights as a small reminder, and at night, you switch to low beams as the basic lighting. However, high beams should only be used on straight, empty roads without other vehicles, as they can dazzle other drivers and are very dangerous. For example, you might use them when driving at night on highways or in rural areas. In rainy or foggy weather, immediately turn on the front or rear fog lights to improve visibility. I’ll never forget the time I was driving at night on a provincial road and forgot the rhyme, using high beams recklessly—it nearly caused an accident. Since then, I’ve always remembered the rhyme to adjust my lights properly. Regularly checking bulbs and wiring is also crucial to avoid sudden headlight failure affecting your driving. In summary, the rhyme helps standardize our operations and enhances safety, especially for new drivers who need more practice.
