LTA said this was why it developed a portable device that could detect illegal modifications by testing an AMD’s top speed even while it is stationary.
Since it was first deployed in November 2025, the devices have contributed to the detection of more than 100 offences and the impoundment of 30 non-compliant devices, it added.
About 20 per cent of these impounded devices could have evaded detection if the speed measurement devices had not been used.
