Highways are designed for continuous and smooth vehicle movement. However, it is often observed that trucks and heavy vehicles are parked randomly along the roadside or partially on traffic lanes during nighttime., In many cases, these vehicles may not have sufficient warning indicators, reflective markings, or proper parking arrangements. Due to low visibility at night, approaching drivers may not notice parked trucks in time, especially at high speeds., I have observed trucks parked near highway edges and sometimes partially occupying road lanes during nighttime. Such parking reduces available road space and increases the possibility of collisions, particularly for fast-moving vehicles., This issue becomes more serious in poorly lit areas or during fog and rain. The problem highlights the gap between highway safety practices and vehicle parking management., Proper parking zones, warning systems, and safe parking practices are important to reduce accident risks on highways.
