Drink Driving in Singapore: What You Need to Know
Drink driving is a criminal offence in Singapore — not a traffic infraction or a quasi-criminal matter. A conviction under section 67 of the Road Traffic Act 1961 carries real criminal consequences: fines, a mandatory driving ban, potential imprisonment, and a permanent criminal record. Even if you feel fine and no accident occurred, you may still be charged if your breath or blood alcohol level exceeds the prescribed legal limit.
This article explains what the law says, what happens after you are charged, and what factors influence how the Court sentences the matter.
What Is the Legal Limit?
Under section 67 of the Road Traffic Act 1961, it is an offence to drive or attempt to drive a motor vehicle while under the influence of alcohol to such an extent that you are incapable of having proper control of the vehicle. You may also be charged simply for exceeding the prescribed alcohol concentration, regardless of how you were actually driving.
The prescribed legal limits are:
Worth knowing: These limits are not high. Depending on your body weight and metabolism, one or two standard drinks may be sufficient to put you over the limit. “I only had a couple of drinks” is not a defence in Court.
How Does a Drink Driving Investigation Begin?
Police typically detect drink driving through roadblocks, traffic enforcement operations, accidents, or observations of erratic driving. If an officer has reasonable cause to suspect you are under the influence, they may require you to take a breathalyser test on the spot.
If you fail the initial test, you will be arrested and required to undergo a more precise evidential breath test at the station. In some cases, a blood or urine sample may also be taken.
Refusing to provide a sample is itself a criminal offence under section 70(4) of the Road Traffic Act and carries equivalent penalties to a drink driving conviction.
What Happens After Arrest?
After arrest, statements will be recorded and you may be released on bail. You will then receive a notice to attend Court. The process under the Criminal Procedure Code 2010 typically involves mention dates, a plea, and — if you plead guilty — a sentencing hearing at which mitigation submissions can be made. If you contest the charge, the matter proceeds to trial. Most drink driving cases, however, are resolved by a guilty plea.
What Are the Penalties?
Penalties are prescribed under section 67 of the Road Traffic Act and depend primarily on your alcohol level, whether this is a first or repeat offence, and whether any accident or injury occurred.
| Offender | Fine | Imprisonment | Driving Disqualification |
|---|---|---|---|
| First offence | $2,000 – $10,000 | Up to 12 months | Minimum 2 years (all classes) |
| Repeat offence | $5,000 – $20,000 | Up to 2 years (mandatory) | Minimum 5 years (all classes) |
| Two or more prior convictions | $5,000 – $20,000 | Up to 2 years (mandatory) | Lifetime disqualification* |
| Enhanced penalties (s 67A) — prior serious traffic convictions | Up to 3× the usual maximum | Up to 3× the usual maximum | At Court’s discretion |
| Accident causing death or grievous hurt | Substantially higher | Years of imprisonment; caning possible (up to 6 strokes) | Long-term or lifetime disqualification |

Fines vs jail: For a first-time offender stopped at a roadblock with no accident and no aggravating factors, a fine is the typical outcome. Imprisonment becomes significantly more likely where there was an accident, injury, very high alcohol levels, or dangerous driving involved.
What Makes a Case More Serious?
Certain factors will lead the Court to treat the matter significantly more harshly:
Where a drink driving incident results in an accident, additional charges may be brought under the Penal Code or the Road Traffic Act — for example, causing hurt by a negligent act, dangerous driving, or causing death by dangerous driving. These carry substantially heavier consequences.
What Can Help at Sentencing?
If you are pleading guilty, your lawyer can make mitigation submissions setting out circumstances relevant to your sentence. Factors the Court commonly takes into account include:
That said, mitigation does not excuse the offence. Singapore Courts place substantial weight on deterrence in road traffic matters. What effective mitigation achieves is ensuring the Court has the full picture and that your sentence is no heavier than the facts warrant.
What Are the Longer-Term Consequences?
Beyond the immediate Court sentence, a drink driving conviction carries practical consequences that can affect you for years:
Why Early Legal Advice Matters
Every drink driving case turns on its specific facts — the alcohol reading, how you were stopped, whether there was an accident, and your personal background all matter. Getting legal advice early allows you to understand exactly what you are facing, make informed decisions about how to proceed, and ensure that any mitigation is carefully prepared and properly placed before the Court.
