NHAI Takes Measures to Enhance Visibility Due to Foggy Conditions

To counter reduced visibility due to foggy conditions on the National Highways during the winter season, NHAI has taken mitigation measures to enhance visibility for the safety of National Highway users.

Engineering Measures
- Reinstallation of missing/damaged road signs and studs to improve guidance.
- Rectification of faded pavement markings for better lane visibility.
- Installation of reflective markers and retro-reflective yellow stickers on crash barriers.
- Solar blinkers at median openings to maximize visibility.
- Barricading and diversion signs at construction stretches to ensure safety.

Safety Awareness Measures
- Variable Message Signs (VMS) displaying fog alerts and speed limits.
- Public Address Systems to warn commuters in foggy areas.
- Electronic billboards, radio, and social media for public service announcements.
- Reflective tapes on vehicles (white in front, red at rear) to enhance visibility.

Operational Steps
- Night-time highway inspections by field offices to identify low-visibility spots.
- Highway Patrol vehicles stationed near dense fog stretches with blinking batons.
- Mandatory reflective jackets for officials and workers.
- Joint drills with traffic police for coordinated emergency response.
- Delegated financial powers to field officers for quick rectification of accident-prone spots.

Driving Advisory for Commuters
- Maintain lane discipline and safe distance.
- Drive at 30 km/hr or less in foggy conditions.
- Use head/back lights blinking for visibility.
- Avoid parking on highways—use designated truck lay bays or wayside amenities.
- Drive cautiously near construction sites and diversions.

👉 In short, NHAI is combining engineering upgrades, awareness campaigns, and operational readiness to ensure safer travel during winter fog, while urging commuters to adopt safe driving practices.
