Moveable guardrails and “Go Slow” boards used by police at night to curb overspeeding must be fitted with retro-reflective tape to improve visibility in foggy conditions, Kolkata Police have instructed all traffic guards across the city. ADVERTISEMENTPolice officers said the tapes significantly improve the visibility of guardrails and barriers placed on roads and at intersections, particularly at night and during early-morning hours when fog reduces visibility. “These tapes, fitted on guardrails and ‘Go Slow’ boards, help alert drivers to hazards and lane edges. The instructions were issued within days of Kolkata traffic police releasing a six-point advisory on social media, urging motorists to “drive safely and arrive safely” during foggy conditions. On stretches such as Red Road, EM Bypass, the Prince Anwar Shah Road connector and Diamond Harbour Road, heavy fog frequently makes it difficult to spot traffic signals from a distance,” an officer said.
