What Changes Occur in Nighttime Visibility Distance?
3 Answers
Nighttime visibility distance changes by becoming shorter. Below is more information regarding vehicle maintenance: Reasons: When a vehicle reaches a certain age or mileage, it will undergo major maintenance to enhance driving safety. Oil Change: The interval for changing oil can range from 5,000 to 10,000 kilometers, depending on the grade of oil used. For example, conventional mineral oil may be changed every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers, and full synthetic oil every 10,000 kilometers. Spark Plug Maintenance: Spark plugs are also one of the important maintenance items, but the replacement cycle depends on the extent of wear. Generally, the replacement cycle ranges from 20,000 to 5,000 kilometers.
I've always felt that the visibility distance is significantly reduced when driving at night. Mainly due to the dim light, the range that the eyes can clearly see becomes smaller, probably only about one-third of that during the day. This increases a lot of risks, such as not being able to spot pedestrians or obstacles on the road in time, and not seeing oncoming cars clearly when turning. I've gotten used to slowing down a bit to allow more reaction time. It's best to regularly check the brightness of the headlights, as aging bulbs or foggy conditions can further reduce visibility. Fatigue driving can also amplify this problem, so I recommend taking more breaks or bringing a friend along for short trips to stay alert through conversation. In short, safety comes first—never take the risk of driving too fast.
From the perspective of the lighting system, the nighttime visibility distance is significantly reduced due to insufficient ambient light. Our headlights can only illuminate a certain distance, typically around several dozen meters. If the bulb quality is poor or there's a wiring issue, the illumination range becomes even shorter. I remember one time when my headlights weren't working while driving, and I almost got into an accident. Regular maintenance of headlight cleanliness and timely replacement is crucial—don't wait until they burn out to fix them. If you're driving too fast, the braking distance might exceed the visibility range, which increases the risk of accidents. I also recommend using fog lights or auxiliary systems to enhance nighttime visibility, as this can help you drive with more confidence.
