As part of the operation, road blocks were set up along Buangkok East Drive, Bukit Batok Road and Bishan Road around midnight.

Later, at about 2.30 am, simultaneous road blocks were also set up along Telok Blangah Road, Kampong Bahru Road and Keppel Road to ring-fence the cluster of entertainment outlets and drinking haunts in the vicinity.

Breathalyser tests were administered to 125 motorists, 16 of whom failed and were arrested for drink-driving. A total of 84 persons were also summoned for other traffic-related offences.

The police reiterate that even if the alcohol content in a driver's blood or breath does not exceed the legal limit, one can still be charged for drink driving if he is unable to control his vehicle properly.

Convicted drink drivers will be disqualified from driving for at least 12 months, which would, in effect, invalidate their driving licences.

In addition, first-time offenders can be fined between $1,000 and $5,000, or jailed up to six months, while repeat offenders face a maximum fine of $30,000 and a mandatory jail term of up to three years.
