The Delhi Transport Infrastructure Development Corporation (DTIDC) had last week decided to fine erring drivers and conductors in an attempt to bring down the alarming levels of noise pollution at ISBTs in Delhi.
The corporation maintains three ISBTs - Kashmere Gate, Anand Vihar and Sarai Kale Khan - in the national capital.
"So far 43 drivers have been fined for honking inside bus terminals. Twenty one conductors have been fined for shouting to solicit passengers," said a transport department official.
The DTIDC said noise pollution at the ISBTs has reached alarming levels and immediate steps were required to address the problem.
It cited frequent use of horn by bus drivers and shouting by conductors as one of the major reasons for noise pollution at the ISBTs.
Roadways buses of several states - Haryana, Punjab, Uttar Pradesh, Jammu Kashmir and Rajasthan - operate from the three ISBTs.
