As motorists zipped along Yishun Avenue 1 at up to 83kmh, 33kmh above the speed limit, a police speed laser camera captured their licence plates.
These motorists were among those who were issued summonses in a week-long operation by the Traffic Police (TP) and Land Transport Authority (LTA) to catch speedsters and illegally modified vehicles.
Of the 71 summonses issued, the police did not say how many were for speeding offences.
During the operation, which began last Monday, the LTA detected 54 offences relating to illegal vehicle modifications, which included modified exhaust systems and non-compliant tinted windows.
The Sunday Times accompanied the authorities early yesterday morning to observe how errant motorists were caught.
Between 1.30am and 2.30am, LTA officers stopped more than 30 vehicles along Yishun Dam for inspections.
The officers were on the lookout for the loud revving of engines from modified exhaust systems and illegal add-ons such as lights.
They lifted the hoods of cars to check their engines and crouched on the ground to inspect exhaust systems. They also verified the driving licences of motorists and notified them of the possible offence they had committed.
Quieter roads during the Covid-19 pandemic led to a fall in the overall number of traffic accidents last year, said the TP in its annual road traffic situation report. But the number of speeding-related accidents increased from 735 in 2019 to 758 cases last year.
A TP spokesman said enforcement operations are conducted regularly at hot spots islandwide to deter errant motorists and detect traffic offences.
Meanwhile, stricter penalties and regular inspections have brought the number of illegal vehicle modification offences down over the past five years.
The number of such offences fell from an average of 1,800 a month in 2015 to 550 a month last year.
A police spokesman said: "The Traffic Police takes a serious view of motorists who choose to flout traffic rules and cause danger to other road users."
