Kota Kinabalu: Some 40 diesel vehicles and 56 motorcycles were inspected during the National Vehicle Operation (Ops Gerak Kebangsaan) in conjunction with the 2025 Sabah State-level Ozone Day, conducted by the Environment Department (JAS) in collaboration with several enforcement agencies on Monday.
JAS Sabah Director Nor Rashidah Mohd Ghazali said seven compounds and five directive notices were issued to vehicle owners who failed to comply with regulations under the Environmental Quality Act 1974.
“The Royal Malaysia Police (PDRM), through the Kota Kinabalu Traffic Investigation and Enforcement Division, issued 23 summonses for various vehicle offences.
“The Road Transport Department (JPJ) issued 80 notices, while the National Anti-Drug Agency (AADK) conducted 30 inspections, all of which passed,” she told the media after the operation at Jalan Tun Fuad Stephens, Taman Awam Likas.

She said the operation aimed to ensure all motor vehicles in Sabah comply with smoke emission standards, noise levels, and the handling of ozone-depleting substances under the Environmental Quality Act 1974.
She said the DOE had also carried out a number of operations throughout the year, including the Static Diesel Operation which saw the inspection of 988 diesel vehicles where as many as 24 investigation papers for compound action and 40 directive notices under Section 48A were issued.
“These notices were issued to vehicle owners who were found to be non-compliant with the permitted emission levels.
They are required to undergo a re-inspection within the specified period after carrying out repair work on the vehicle, as well as to undergo Puspakom inspection to confirm compliance,” she said.
Meanwhile, the DOE inspected 14 air-conditioning service premises in order to ensure technicians possessed certified licences to handle refrigerants as well as to make sure workshops have gas recovery and recycling systems.
“We have also implemented 229 remote surveillance operations using roadside cameras, focused on monitoring black smoke emissions from diesel vehicles, in which we have issued 33 directive notices for vehicles emitting black smoke,” Nor Rashidah added.
“Today, the focus was on motorcycles with excessive noise and diesel vehicles from commercial companies emitting black smoke,” she added.
Nor Rashidah also advised diesel vehicle owners, including public and private transport companies, to carry out regular engine maintenance, use quality lubricants, and ensure exhaust systems, catalytic converters, and other components are in proper working order.
The National Vehicle Operation, held alongside the 2025 Sabah State-level Ozone Day, saw multiple enforcement agencies working together to uphold environmental standards.
