India, Dec. 22 -- Dense fog, toxic smog and the IMD's orange alert over Delhi's persistently low visibility have returned with a familiar warning: drive safe, or don't drive at all. The risks are already playing out on the roads. Just days ago, dense fog on the Delhi-Mumbai Expressway triggered a major pile-up near Raniyala Patakpur village involving over 15 vehicles, while another collision in Faridabad claimed two lives. Amid this haze, good Samaritans are stepping in to make the city's roads safer, one reflective strip at a time.

Two-wheeler riders remain especially vulnerable. "Motorcycles are lower in height and often missed by larger vehicles," Yadav explains. "We place triangular red reflective stickers on their helmets and station volunteers at night checkpoints toassist drivers and traffic police." Community-led efforts are also gaining momentum. Rajni Gandhi from TRAX NGO works directly with two-wheeler, auto and e-rickshaw drivers during heavy fog hours. "We encourage reflective jackets, bright clothing and explain how reflective tapes can significantly improve visibility," she says. Pedestrians, too, face heightened risk, and Gandhi's team audits crossings and junctions across the city, for clearer lane markings, visible zebra crossings and highlighted dividers....
