The High Court ordered owners and drivers of vehicles with hydraulic horns to submit their horns to the police stations in 15 days.
The HC also asked police to destroy these horns.
A High Court bench comprising justice Rezaul Haque and justice Mohammad Ullah passed the order on Sunday.
Human Rights and Peace for Bangladesh, a human rights and environmental organisation, filed a writ petition on 22 August challenging the ineffectiveness in stopping the use of hydraulic horn to check sound pollution.
On 23 August, the HC issued a rule after the primary hearing of the writ petition.
Defendants were asked to submit reports on the implementation of the rule.
Accordingly, Bangladesh Road Transport Authority (BRTA) chairman and Dhaka Metropolitan Police (DMP) commissioner and joint commissioner (Traffic) submitted separate reports.
The petitioner’s counsel Manzil Murshid told Prothom Alo, according to reports hundreds of hydraulic horns had been seized. A fine of Tk 100 is to be imposed, according to the law.
