Think you can race to work because there's no cop watching? Think again. The traffic police are always watching, thanks to 40 speed detection cameras installed across the city. The cameras have been issuing e-challans to violators on a trial basis since December 30. If the initiative works, the department will instal more such cameras. The new cameras will not only detect vehicles over the speed limit, but will automatically generate e-challans for the violators as well.
