Gurugram, Nov. 2 -- Massive traffic snarls stretching for up to 5 km from Sarhaul toll plaza were seen on National Highway-48 on Sunday morning as the Delhi government's ban on the entry of vehicles below the BS-VI emission standard took effect. The curbs only apply to vehicles not registered in Delhi. The congestion caused by the border checks affected the flyover coming from Shankar Chowk, the main carriageway and the service lane on NH-48. According to the Gurugram traffic police, team of around 50 personnel, including traffic police and Haryana Police personnel, was deployed at the site to check vehicles. The Delhi government has imposed a ban on the entry of all non-Delhi diesel and petrol vehicles below the BS-VI emission standard from November 1 to January 31 next year. The restrictions apply to petrol and diesel vehicles registered outside Delhi that do not meet BS-VI emission standards, including BS-III and BS-IV vehicles, in Gurugram. However, according to Gurugram traffic police personnel deployed on the ground, even Delhi-registered petrol and diesel vehicles below the BS-VI emission standard were not being allowed to enter the national capital. Vehicles found to be below the prescribed emission standard were being challaned and sent back. The snarls on the Gurugram-Delhi triggered long queues, troubling many commuters, with some stuck in traffic for over two hours. "We have been stuck for two hours, it has been so tiring," said Reshma Patel, who was heading to Delhi. Patel was initially stuck on the flyover from Shankar Chowk towards Delhi before spending another 30 minutes near the toll plaza. Vikas Kumar, a cab driver travelling from Maruti Kunj, was stuck in traffic for over an hour. Lokesh Verma, a Sector 54 resident, said he too was held up for nearly two hours as police checked vehicles near the toll plaza....
