Triangular filled area refers to the channelizing line. Below is a partial introduction about the triangular filled area: Definition: It primarily consists of one or several white V-shaped lines or diagonal lines set according to the terrain of the intersection, indicating that vehicles must drive along the prescribed route and are not allowed to cross or drive over the lines. It is mainly used for wide, irregular, or complex intersections with challenging driving conditions. The purpose is to ensure that every vehicle can "stay in its lane," serving to regulate, guide, and warn traffic. Traffic regulations: According to Articles 38 and 44 of the Traffic Law, channelizing lines are a type of prohibited marking. Vehicles must drive along the prescribed route and are not allowed to cross or drive over the lines, nor are they permitted to make U-turns or park arbitrarily within the channelizing line area. Violations may result in a penalty of 3 demerit points for the driver.

The triangular filler area on a car usually refers to the sealant-filled parts around the windshield or windows, especially in the triangular corners of the body, ensuring the glass is fixed and waterproof. Having driven for over a decade, I once experienced water leakage in the backseat after rain, which was caused by aging and cracking sealant in this area. Upon inspection, hardened or cracked filler in the corners allowed water to seep in quietly, not only wetting the interior but also causing rust. After washing the car, simply touch this area—if it feels moderately soft, it's fine; otherwise, head to a repair shop for resealing immediately. Though small, it's crucial. Older cars are prone to neglect, so a monthly check is recommended to maintain sealing and avoid trouble.

As someone who frequently works on cars, let me put it simply: The triangular filler area refers to the black rubber-like substance around the edges of your car's windshield, professionally called sealant. Its purpose is to firmly bond the glass to the car body, preventing water leaks and reducing wind noise. If it cracks or becomes uneven, like in my case last time, you'll hear a whooshing sound when driving at high speeds—later we found out it was due to worn sealant allowing air to seep in. For a quick check, press it with your finger; if it feels soft and elastic, it's fine, but if it's hard, it needs replacement. Modern cars use polymer materials, which last longer, but regular inspections are a must. Generally, have a mechanic check the thickness with professional tools every two years—it saves money and gives peace of mind.

The triangular filler area is essentially the sealing rubber layer at the corners of the car window, used to seal gaps. Without it, the glass would become loose and water leakage would occur. With over 20 years of truck driving experience, I've seen too many novices overlook this small component, leading to major repairs. The actual operation is quite simple: after parking, just take a glance at the edges of the windshield. The rubber at the triangular area should be smooth and free of cracks. Once cracks appear, they can easily accumulate water and corrode the car frame. Replacing the rubber is inexpensive, and addressing it early can save you thousands in damages. Remember, this is a crucial part of driving safety—don't delay.

For my fellow female car enthusiasts, the triangular filler area refers to those small black circles at the corners of the windshield. They serve not only for safety sealing but also affect the overall aesthetic appearance. My own car once experienced aging adhesive turning gray and rough, making it look worn and unattractive. It improved significantly after getting it re-glued at the shop. Daily is quite easy - just wipe it with a soft cloth during car washes to keep it clean and prevent dust accumulation and cracking. Taking care of this small detail makes me feel much more confident when driving out.
