Drink driving is a serious traffic offence in Singapore. It generally refers to driving or attempting to drive a motor vehicle while sufficiently affected by alcohol that you cannot properly control the vehicle, or while the proportion of alcohol in your breath or blood exceeds the prescribed legal limit.
The consequences can extend far beyond receiving a traffic fine. A person convicted of drink driving may face thousands of dollars in fines, imprisonment and years of driving disqualification. Repeat offenders face substantially heavier punishment, while cases involving accidents, injuries or dangerous driving can become considerably more serious.
As of September 2026, drink driving is principally dealt with under Section 67 of the Road Traffic Act 1961.
This guide explains what constitutes drink driving in Singapore, the penalties that may apply, how alcohol readings affect sentencing, what happens to your driving licence and what motorists should know if they are investigated or charged.

What Is Drink Driving in Singapore?
Under Section 67(1) of the Road Traffic Act, a person commits an offence when driving or attempting to drive a motor vehicle on a road or other public place if either of two situations applies.
First, the person may be unfit to drive because they are under the influence of alcohol, a drug, psychoactive substance or intoxicating substance to such an extent that they are incapable of having proper control of the vehicle.
Second, the person may have so much alcohol in their body that the proportion of alcohol in their breath or blood exceeds the prescribed limit.
This distinction is important because drink driving is not simply about whether someone appears visibly drunk.
A person could be speaking normally, walking normally and personally believe that they are capable of driving, but still have an alcohol reading exceeding the prescribed limit.
Likewise, motorists should not treat a statutory alcohol limit as a recommended amount to drink before driving.
Drink Driving Is Not the Same as “Feeling Drunk”
One of the biggest misconceptions about drink driving is that a person needs to be obviously intoxicated before an offence occurs.
That is not the case.
The law includes an objective alcohol-limit offence. Consequently, statements such as:
“I didn’t feel drunk.”
“I only had two drinks.”
“I could walk perfectly normally.”
“I’ve driven after drinking before.”
are not themselves answers to whether an offence has been committed.
How someone feels after drinking and the amount of alcohol actually present in their body are different questions.
This is why the safest practical approach remains straightforward: if you are going to drink, do not drive.
How Many Drinks Can You Have Before Driving?
There is no reliable universal answer.
It is misleading to say that every person can safely have one beer, one glass of wine or one whisky before driving.
The amount of alcohol in a person’s body after drinking can vary according to numerous factors, including body composition, the amount consumed, strength of the alcoholic beverage, serving size, speed of consumption, elapsed time and individual physiology.
Even the phrase “one drink” is ambiguous.
A small bottle of ordinary beer and a large pint of strong craft beer are both commonly described as one drink. Similarly, a cocktail may contain considerably more alcohol than a single serving of wine.
The law is therefore not based on simply counting glasses.
What Is the Penalty for Drink Driving in Singapore?
Singapore imposes significant penalties for a conviction under Section 67.
For a first conviction, a person is liable to:
a fine of between S$2,000 and S$10,000;
imprisonment for up to 12 months;
or both.
The Singapore Police Force reiterated these penalties as recently as August 2026.
However, these are not the only consequences.
Driving disqualification can be one of the most significant aspects of a drink-driving conviction.
Will You Lose Your Driving Licence for Drink Driving?
A first conviction ordinarily attracts a driving disqualification of at least two years, subject to the statutory provisions concerning special reasons.
The Road Traffic Act requires the court, in the relevant first-conviction case, to order a period of disqualification equal to or longer than the specified period unless the court for special reasons thinks fit not to order disqualification or to order a shorter period.
Therefore, someone should not look at a drink-driving case as merely:
“I’ll pay a fine and move on.”
The loss of driving privileges can be a major part of the punishment.
For someone who needs to drive for work, business or family responsibilities, two or more years without a driving licence can have substantial practical consequences.
How Does the Alcohol Reading Affect the Sentence?
Alcohol readings can have a significant influence on sentencing.
The Attorney-General’s Chambers publishes prosecution sentencing tariffs for certain cases under Section 67(1)(b).
For cases falling within the published framework—among other things, a first-time drink-driving offender who pleads guilty and whose offence did not result in an accident—the prosecution’s positions for an early guilty plea at the mentions stage currently include:
| Breath alcohol reading | Prosecution’s sentencing position |
|---|---|
| 40–44 µg/100ml | S$2,000 fine + 24 months’ disqualification |
| 45–54 µg/100ml | S$2,500 fine + 24 months’ disqualification |
| 55–62 µg/100ml | S$4,000 fine + 30 months’ disqualification |
| 63–69 µg/100ml | S$4,500 fine + 30 months’ disqualification |
| 70–79 µg/100ml | S$6,000 fine + 36 months’ disqualification |
| 80–89 µg/100ml | S$6,500 fine + 36 months’ disqualification |
| 90–99 µg/100ml | S$8,000 fine + 48 months’ disqualification |
| 100 µg/100ml or above | S$8,500 fine + 48 months’ disqualification |
These are prosecution sentencing positions, not automatic sentences. AGC expressly states that the court—not the prosecution or police—ultimately determines the appropriate sentence.
This is an important distinction.
A website should therefore avoid suggesting that a particular alcohol reading automatically produces a particular sentence in every case.
Can You Go to Jail for Drink Driving?
Yes.
Even for a first conviction, Section 67 allows imprisonment of up to 12 months.
Whether imprisonment is imposed depends on the applicable law and circumstances of the individual case.
Factors can include the seriousness of the conduct, alcohol level, whether there was an accident, manner of driving, previous convictions and other relevant circumstances.
The position becomes substantially more severe for repeat offenders.
What Is the Penalty for a Second Drink-Driving Offence?
Singapore treats repeat drink driving much more severely.
For a second or subsequent conviction, Section 67 provides for:
a fine of between S$5,000 and S$20,000; and
imprisonment for up to two years.
The Singapore Police Force describes imprisonment for a second or subsequent conviction as mandatory.
Driving disqualification consequences also become significantly more serious for repeat offenders.
This means someone with a previous drink-driving conviction should not assume that a second case will simply result in another fine.
What Happens After Multiple Drink-Driving Convictions?
The Road Traffic Act contains escalating disqualification consequences for repeat offending.
Broadly, the statutory framework provides significantly longer disqualification periods for repeat offenders, with lifetime disqualification potentially arising for persons with multiple relevant previous convictions.
The precise treatment depends on the person’s conviction history and the statutory provisions applying to the particular case.
This escalating structure reflects the seriousness with which Singapore treats repeated drink driving.
What If You Drink and Drive but Do Not Cause an Accident?
An accident is not required for a drink-driving charge.
This is extremely important.
Police can conduct enforcement checks and administer breathalyser tests. Motorists can be arrested and charged after failing those tests even where no collision occurred.
For example, in April 2026, Singapore Police announced that 15 motorists were to be charged with drink driving after arrests made between February and April following failed breathalyser tests during enforcement checks.
Therefore:
No accident does not mean no offence.
A motorist does not need to hit another vehicle, damage property or injure someone before a drink-driving prosecution can arise.
What If Drink Driving Causes an Accident?
The legal situation can become considerably more serious.
A driver involved in an accident may face a drink-driving charge together with other traffic offences depending on the circumstances.
For example, the authorities may investigate whether the manner of driving amounted to careless or dangerous driving.
If someone is injured, the consequences can escalate further.
In June 2026, Singapore Police announced a case involving a driver who was to be charged with dangerous driving causing hurt, drink driving and other traffic offences following a collision.
Therefore, a drink-driving case involving an accident should not automatically be compared with a straightforward roadblock case.
The facts matter.
What If Someone Is Seriously Injured?
When irresponsible driving causes hurt, grievous hurt or death, additional offences and substantially more severe penalties can potentially become relevant.
The Singapore Police Force’s traffic-offence framework sets out enhanced criminal penalties for irresponsible driving offences, including offences causing injury.
A case involving serious injury or death therefore requires careful analysis of all potential charges rather than considering the drink-driving offence in isolation.
Can You Get Arrested at a Roadblock?
Yes.
Police officers have statutory powers relating to preliminary breath tests and arrest.
Under Section 69 of the Road Traffic Act, a police officer or immigration officer may, in specified circumstances, arrest a person without a warrant following a preliminary breath test where there is reasonable cause to suspect that the proportion of alcohol exceeds the prescribed limit.
Roadside enforcement is therefore an important part of Singapore’s drink-driving regime.
What Happens If You Refuse a Breath Test?
Refusing to provide a required breath specimen is not a simple way to avoid the consequences of suspected drink driving.
Under Section 69, a person who, without reasonable excuse, fails to provide a required specimen of breath commits an offence.
For a first conviction for that offence, the statutory punishment is:
S$1,000 to S$5,000 fine, imprisonment for up to six months, or both.
For a second or subsequent conviction, the punishment increases to:
S$3,000 to S$10,000 fine and imprisonment for up to 12 months.
Accordingly, motorists should not assume that refusing to cooperate with a lawful breath-test requirement will prevent legal consequences.
What If You Are Not Driving but Are Sitting in the Car?
Singapore law also separately addresses being in charge of a motor vehicle while under the influence of drink, even where the person is not actually driving.
Section 68 covers a person who is in charge of a motor vehicle on a road or other public place but is not driving and is either unfit through alcohol or has alcohol exceeding the prescribed limit.
For a first conviction under Section 68, the punishment is a fine of S$500 to S$2,000 or imprisonment for up to three months.
For a second or subsequent conviction, the punishment increases to a fine of S$1,000 to S$5,000 and imprisonment for up to six months.
Section 68 also contains provisions concerning when a person is deemed not to have been “in charge”, so the precise circumstances matter.
Can You Sleep in Your Car After Drinking?
This can be legally complicated.
Simply deciding not to drive after drinking is obviously safer than driving, but someone should not automatically assume that sitting or sleeping in the driver’s seat eliminates every possible legal issue.
As explained above, Section 68 separately deals with being in charge of a motor vehicle while under the influence or above the prescribed limit.
If you have been drinking, the safer practical choice is usually to arrange alternative transport rather than attempting to sleep in a vehicle with the intention of driving later.
What About Driving the Next Morning?
Another common misconception is that alcohol disappears completely after sleeping for several hours.
That is not necessarily true.
Alcohol can remain in the body the following morning, particularly after substantial late-night drinking.
A person who stopped drinking at 2 a.m. should not automatically assume that they are fit to drive at 7 a.m. simply because they slept.
Coffee, cold showers, breakfast or drinking water should not be treated as guarantees that the person is legally fit to drive.
Can Drink Driving Affect Your Employment?
Potentially.
Driving disqualification can be particularly disruptive for people whose employment requires them to drive, including delivery drivers, private-hire drivers, technicians, salespeople, logistics personnel and business owners.
A criminal conviction can also potentially have consequences where an employer, regulator, licensing authority or other organisation requires disclosure of relevant convictions.
The precise effect depends on the individual’s employment and professional circumstances.
Importantly, needing a driving licence for work does not automatically mean that a person will avoid the statutory consequences of a drink-driving conviction.
Does Pleading Guilty Reduce the Penalty?
A guilty plea can be relevant to sentencing, but defendants should understand their legal position before deciding how to plead.
AGC expressly states that an accused person has the choice whether to plead guilty or claim trial and is entitled to seek legal advice concerning whether to plead guilty, whether any defence applies and whether relevant circumstances or mitigating considerations may affect sentencing.
An accused person should therefore not plead guilty simply because they assume there is no alternative.
The evidence and circumstances should first be understood.
What Is Mitigation in a Drink-Driving Case?
Where a person pleads guilty or is convicted, mitigation concerns relevant information placed before the court for consideration when determining the appropriate sentence.
Depending on the case, mitigation may address the offender’s circumstances, conduct, plea and other legally relevant matters.
However, mitigation should not be confused with a guarantee of avoiding punishment.
The court remains bound by applicable legislation and sentencing principles.
Similarly, the fact that someone is a first-time offender, needs their vehicle for work or regrets their actions does not automatically eliminate a statutory driving-disqualification requirement.
Why Are Drink-Driving Penalties So Serious?
The reason is straightforward: drink driving creates risks not only for the driver but for passengers, pedestrians, cyclists, motorcyclists and other motorists.
Alcohol can affect judgement, concentration, coordination and reaction.
A driver may believe they are capable of driving normally while their actual ability to respond to unexpected road conditions has deteriorated.
Singapore Police continues to conduct active enforcement against drink driving. In August 2026, Police announced that 31 motorists were to be charged with drink-driving offences and reiterated that motorists intending to consume alcohol should not drive.
What Should You Do If You Plan to Drink?
The most reliable approach is to arrange transportation before drinking.
That could mean taking public transport, using a taxi or private-hire vehicle, having a designated non-drinking driver, arranging for someone to collect you, or using an appropriate valet service.
Singapore Police has similarly encouraged motorists who intend to consume alcohol to use alternative transportation rather than drive.
Leaving your car somewhere overnight is inconvenient.
Losing your driving licence for years, paying thousands of dollars in fines or facing imprisonment is considerably more serious.
Summary of Drink-Driving Penalties in Singapore
For a straightforward Section 67 offence, the key statutory penalties can be summarised as follows:
| Conviction | Fine | Imprisonment |
|---|---|---|
| First | S$2,000–S$10,000 | Up to 12 months |
| Second or subsequent | S$5,000–S$20,000 | Up to 2 years |
A first offence can result in a fine, imprisonment or both. A second or subsequent conviction attracts both the prescribed fine and imprisonment framework. Driving disqualification is an additional major consequence.
The actual sentence in an individual case depends on the applicable law and facts. Alcohol readings, previous convictions, whether an accident occurred and other circumstances can materially affect the outcome.
Do You Need a Drink Driving Lawyer in Singapore?
Not every person charged with an offence is required to engage a lawyer, but someone facing a drink-driving investigation or prosecution may wish to obtain legal advice before deciding how to proceed.
A drink driving lawyer in Singapore can review the charge and available evidence, explain the potential penalties and driving disqualification consequences, advise whether any defence may apply and assist with mitigation or court representation where appropriate.
Legal advice can be particularly important where the case involves a high alcohol reading, previous drink-driving conviction, accident, injuries, alleged dangerous driving or multiple charges.
Drink driving should ultimately be understood as much more than a traffic ticket. Under Singapore law, it is a criminal offence capable of resulting in a substantial fine, imprisonment and lengthy loss of driving privileges.
The safest approach remains simple: if you intend to drink, arrange another way home and do not drive.
