The Traffic Police arrested 18 motorists, aged between 29 and 48, for drink-driving in an island-wide operation on Tuesday morning.

A total of 76 drivers were stopped and tested for alcohol consumption in the pre-dawn operation where road blocks were set up at various parts of Singapore, said a police statement on Wednesday.

Of the 18 men arrested, one driver had 110 micrograms of alcohol per 100ml of breath - more than triple the prescribed legal limit of 35 micrograms.

If convicted, drink drivers will be banned from the roads for at least 12 months. They will lose their driver's license and must retake and pass the theory and practical driving tests before they are allowed to return to the roads, added the statement.

First-time offenders can also be fined between $1,000 and $5,000, while repeat offenders may be fined up to $30,000, and sentenced to a mandatory jail term of up to three years. If they cause death or serious injury, they may also punished with up to six strokes of the cane.

Commander of Traffic Police, Assistant Commissioner of Police Cheang Keng Keong, said the Traffic Police will continue conducting regular road blocks to deter and detect drink drivers.

"Every one of us has a part to play in making our roads safe in Singapore. For your loved ones and for your own safety and the safety of other road users, I urge every motorist never to attempt to drive after consuming alcohol."
