Why speed limit on Noida and Yamuna expressways will drop from Dec 15

Authorities will reduce the speed limit on the Noida–Greater Noida Expressway and Yamuna Expressway from December 15, 2025, as part of a winter safety measure aimed at preventing accidents during the fog season.

The decision follows a consistent pattern of low visibility, slippery road conditions and a spike in speeding violations recorded every winter.

Under the revised norms, light vehicles that are currently allowed to travel at 100 km/h will now be restricted to 75 km/h, reported The Hindustan Times. Heavy vehicle limits will remain unchanged — 60 km/h on the Yamuna Expressway and 50 km/h on the Noida–Greater Noida Expressway.

A senior traffic official said the call was taken in view of deteriorating visibility expected during December and January.

The seasonal fog layer in the NCR region reduces stopping distance and reaction time for drivers, making high-speed travel particularly risky on long, straight stretches of both expressways.

“A meeting will be conducted with the Noida Authority soon to review the situation and the speed limit will be reduced. The revised limit will also be visible on Google Maps,” Dr Pravin Ranjan Singh, deputy commissioner of police (Noida Traffic) told The Hindustan Times.

The advisory will remain in force for roughly two months, depending on weather conditions.

Rising challans, accident data prompted the move

Between January and October 2025, over 59,242 challans were issued for speeding on the two expressways.

Officials said past accident data also guided the decision. In 2024, the expressways together reported 462 deaths and 966 injuries in road crashes.

Police said most winter accidents occur due to overspeeding in fog, when drivers fail to spot slower vehicles ahead.

Safety advisories being pushed at toll plazas

To prepare commuters for the seasonal change, toll staff at Jewar, Mathura and Agra plazas have begun distributing safety advisories.

Drivers are being asked to ensure their vehicles are winter-ready — including functioning fog lamps, clean windscreens and working rear-glass defoggers.

Officials said the goal is to reduce collision impact and allow drivers more reaction time during the months when visibility drops sharply in the early morning and late evening.
