Summary:
NEW DELHI: Trucks carrying illegally mined sand and gravel enter the city through unmonitored roads past 11pm every day. Delhi government limits the entry of heavy vehicles into the city to a period between 11pm and 7am, mainly as a preventive measure against pollution. But the roads have a thin police presence at night, and the vehicles have a free rein of the roads. There are check posts at 11 border points, but the remaining 12 offer opportunities for them to slip in unchallenged. These also have the maximum violation of norms by trucks..
