The Motor Vehicles Department (MVD) continued its drive against buses operating in the district without speed governors for the second day on Sunday.
Notably, buses of the Kerala State Road Transport Corporation (KSRTC) were not exempted from the crackdown.
The fitness certificates of 108 service buses, including seven KSRTC buses, were cancelled after being found that the mandatory speed governors were either tampered with or removed.
Notices were also served on 51 buses, including nine operated by the KSRTC, to improve the functioning of the installed speed governors.
According to MVD officials, the inspections brought to light several violations of the prescribed norms by bus owners.
It was found that while many buses had faulty brakes, some did not even have doors. Owners have also been directed to remove audio systems and air horns that were installed in some buses.
The drive was led by R.T.O. T.J. Thomas and Joint R.T.O. Prakash Babu. The checks were conducted in different places including Kottayam, Changanassery, Ettumanoor, Vaikom, Pala and Kanjirappally.
During the inspection within the private bus station at Nagampadom, action was taken against 13 erring vehicles.
There were also cases in which the speed governors were removed after receiving approval from the MVD.
During the inspections on Saturday, fitness certificates of 20 buses and five tipper lorries had been cancelled.
MVD officials have informed that the inspections will continue and the bus operators against whom action has been taken will be permitted to operate services only after they adhere to the norms.
