December 17, 2025 (Navroze Bureau) ; Chandigarh experienced the season’s first spell of dense fog, marking the onset of winter weather conditions in the region. Reduced visibility during early morning hours disrupted traffic movement and prompted authorities to issue advisories for motorists, urging caution while driving on city roads and highways.
The sudden drop in visibility served as a reminder for residents that fog-related risks increase significantly during winter, particularly in northern India. With more foggy mornings expected in the coming weeks, traffic officials and safety experts are emphasising the importance of preparedness and responsible driving.
Fog Reduces Visibility Across City
Several areas of Chandigarh reported visibility dropping sharply during the early hours, especially on open stretches, flyovers, and highways connecting Panchkula and Mohali. Commuters travelling to work or schools faced slower traffic, while long-distance vehicles were advised to delay travel where possible.
Fog forms when moisture in the air condenses near the ground, a phenomenon common during winter nights with low wind speed and falling temperatures. Experts warn that visibility can change suddenly, catching drivers off guard.
Why Foggy Driving Is Dangerous
Driving in fog is particularly risky because:
- Depth perception becomes difficult
- Other vehicles may appear suddenly
- Brake lights and road signs are harder to see
- Speed judgement is impaired
Most fog-related accidents occur due to over-speeding, tailgating, or misuse of headlights, officials noted.
Essential Safety Tips for Driving in Fog
Authorities and road safety experts have issued the following key driving precautions for foggy conditions:
1. Drive Slowly and Steadily
Reduce speed significantly and avoid sudden acceleration or braking.
2. Use Low-Beam Headlights or Fog Lamps
High-beam lights reflect off fog droplets and reduce visibility further. Use low beams or fog lights instead.
3. Maintain Safe Distance
Keep a larger-than-usual gap between your vehicle and the one ahead to allow adequate reaction time.
4. Follow Road Markings
Use lane markings and reflective road studs as visual guides when visibility is low.
5. Avoid Overtaking
Sudden lane changes or overtaking can be extremely dangerous in fog.
6. Use Indicators Early
Signal turns and lane changes well in advance to alert other drivers.
7. Avoid Sudden Stops
Brake gradually to prevent rear-end collisions.
8. Pull Over Safely if Needed
If visibility drops dangerously low, park at a safe spot away from the road with hazard lights on.
Advisory for Two-Wheeler Riders
Two-wheeler riders are particularly vulnerable during foggy conditions. Officials recommend:
- Wearing reflective clothing
- Using proper headgear
- Avoiding early-morning rides when fog is densest
Traffic Police on Alert
Chandigarh Traffic Police have increased patrolling in fog-prone zones and are monitoring traffic flow during peak hours. Officials said challans may be issued for misuse of high-beam headlights, which often worsen fog glare for other drivers.
Traffic helplines and emergency response teams have also been placed on standby to handle accidents or vehicle breakdowns.
Weather Outlook
Meteorological officials predict more foggy mornings over the next few days as temperatures continue to fall. Clear afternoons are expected, but early mornings and late nights may see persistent fog, especially in low-lying areas.
Residents have been advised to plan travel accordingly and allow extra time for commutes.
Public Awareness Is Key
Road safety experts stress that most fog-related accidents are preventable with responsible driving behaviour. Awareness, patience, and adherence to traffic rules play a crucial role in ensuring safety during winter conditions.
Conclusion
As Chandigarh witnesses the season’s first fog, authorities are urging residents to prioritise safety over speed. With winter setting in, following fog-driving precautions can help prevent accidents and ensure smoother travel during challenging weather conditions.
Summary
The season’s first fog has hit Chandigarh, reducing visibility and prompting authorities to issue driving advisories, urging motorists to slow down, use proper lights, and follow safety precautions.
