That’s the number of motorists who left their engines running while their vehicles were stationary.
That act has been instituted as a summon-able offence, after changes to the Environmental Protection and Management Act made in 2008.
Offenders can be fined between S$70 and S$2000, while repeat offenders can incur up to a S$5000 fine.
Environment and Water Resources Minister Masagos Zulkifli said in parliament on Monday that the 1,000-fold spike is largely due to greater enforcement and more complaints from the public.
He added that some motorists falsely believe that engines needed to be warmed up to get better fuel efficiency or to make the engine last longer.
Singapore isn’t the only country to institute such fines for stationary vehicles.
In Hong Kong, the Motor Vehicle Idling (Fixed Penalty) Bill was passed in March 2011, making it an offence to idle for more than three minutes per hour.
Similar rules apply in Europe, where guidelines for turning engines off are 10 seconds in Italy and France, 20 seconds in Austria, 40 seconds in Germany and 60 seconds in the Netherlands.
And over in the United States, thirty-one have put in place their own anti-idling regulations.
