DMP meanwhile continued to impose penalties on motorists who remained defiant to the ban. Since Thursday until Saturday night traffic sergeants prosecuted over 761 motorists under which an offender has to pay a fine of Tk 200 under the clause 139 of motor vehicle act.

On February 16, DMP said it decided to implement the motor vehicles ordinance of 1983 that forbids honking horns within 200 yards of places of worship, educational institutes, hospitals, courts and offices.

Moreover, in a bid to turn the city's noise level down, DMP has primarily banned honking horns on VIP road between the stretch of Sonargaon intersection and Bangabandhu Sheikh Mujib Medical university intersection.

But most of the motorists in the city still remain unaware of this sudden implementation of the old law due to DMP's inadequete publicity in this regard.

In Sonargaon, Bangla Motor, Shahbagh, Panthapath this correspondent found only one banner urging motorists not to blow horns. On-duty sergeant Iqbal Hossain at the Sonargaon intersection however claimed that they had put up banners at Bangla Motor and beyond.

"Motorists will stop honking unnecessarily but it will take some time, we need to grow awareness among the road users," said Iqbal.

Indiscriminate use of vehicular horns in this city is the major cause of serious noise pollution that has turned the city into one of the noisiest urban areas in the world.
