5 Accident‑Prone Roads In Delhi NCR To Avoid During Dense Fog

On December 15, 2025, a massive pile‑up involving nearly 20 vehicles occurred on the Delhi-Mumbai Expressway near Nuh, Haryana, killing four people, including two police officers. This tragic incident highlights the dangers of driving in dense fog, which is common in Delhi NCR during winter. With AQI levels also in the “Severe+” category, visibility has dropped drastically across the region. Here are five major roads and highways that become particularly hazardous during foggy conditions.

Delhi-Mumbai Expressway (Nuh Stretch): The newly-built expressway has quickly become a hotspot for fog‑related accidents. The wide lanes and high speeds, combined with sudden drops in visibility, make it extremely dangerous. The recent 20‑vehicle collision underscores the risks of driving here during early mornings and late nights.

Yamuna Expressway (Greater Noida to Agra): Known for high‑speed travel, the Yamuna Expressway often witnesses pile‑ups in winter fog. The long, straight stretches encourage speeding, but near‑zero visibility can lead to chain collisions. Commuters are advised to slow down drastically and use fog lights.

Delhi-Meerut Expressway: This busy corridor connecting Delhi to western Uttar Pradesh sees heavy traffic, including trucks and buses. Dense fog reduces visibility to a few meters, increasing the risk of rear‑end collisions. The mix of local traffic and high‑speed vehicles makes it particularly accident‑prone.

NH‑48 (Delhi-Gurugram-Jaipur Highway): One of the busiest highways in NCR, NH‑48 is notorious for fog‑related accidents. Heavy truck movement combined with poor visibility often leads to multi‑vehicle crashes. The Gurugram stretch, with its flyovers and intersections, is especially risky during foggy mornings.

Outer Ring Road, Delhi: Within the capital, the Outer Ring Road is a major arterial route that becomes treacherous in fog. Frequent intersections, flyovers, and mixed traffic (cars, buses, two‑wheelers) increase the chances of accidents when visibility drops. Commuters should avoid unnecessary travel here during peak fog hours.

Safety Tips for Commuters: Avoid early morning and late night travel when fog is thickest. Use fog lights and hazard lights to improve visibility. Maintain low speeds and keep a safe distance from other vehicles. Follow traffic advisories and check weather alerts before traveling. Prefer public transport when possible to reduce personal risk.
