Mumbai Traffic Police has quietly come up witha unique initiative to discipline the city's perpetual honkers, who love to blare the horns of their vehicles even when the traffic signal is red. Honking is not only a bad habit, but also an act of traffic indiscipline besides being a major health and pollution hazard. In Mumbai, 149 and 460 honkers were booked in 2018 and 2019 respectively for honking offences.
