Drink Driving Laws in Singapore 2023: How Much Alcohol Can You Drink and Drive?

In Singapore, motorists must adhere to a designated blood alcohol concentration (BAC) threshold, set at 0.08% or 0.8 grams of alcohol per liter (g/L) of blood. Typically, it takes approximately one to two drinks for most people to reach a BAC level of 0.08%. However, this estimate depends on various factors and an individual’s physiology.

The objective of this webpage is to educate and increase awareness about the hazards linked to drunk driving in Singapore. It is crucial to emphasize that this site does not endorse or support drinking and driving in any place or country.

In 2022, Singapore experienced a significant increase in drink-driving accidents, reaching 175 cases, the highest since 2018 when stricter penalties were proposed. While the number of fatal accidents and fatalities related to drunk driving has been decreasing since 2018, there was a surge following the resumption of nightlife activities in April 2022.

Fatal drink-driving accidents rose by 25%, from eight cases in 2021 to 10 in 2022. Additionally, the number of individuals arrested for drunk driving increased by 16%, from 1,453 in 2021 to 1,685 in 2022.

We want to emphasize the importance of refraining from driving after consuming alcohol because it not only puts your own safety at risk but also endangers other drivers on the road.

To reduce potential dangers, consider alternative transportation options such as designated driver services, taking a taxi, or using other safe means of transportation if you need to travel after drinking alcohol.

Understanding and being aware of the drunk driving laws in the country you are in is crucial. It is also essential to monitor your blood alcohol level using an alcohol breathalyzer to ensure you know your accurate BAC level.

When Can You Drink and Drive in Singapore?

As previously mentioned, several factors, such as gender, can impact an individual’s BAC level. Research suggests that men and women have different BAC levels due to the higher presence of alcohol dehydrogenase (ADH) enzymes in men’s bodies, which aid in alcohol metabolism. As a result, men tend to metabolize alcohol more quickly than women.

The consumption of alcohol can have detrimental effects on vision and increase the risk of accidents. Therefore, it is advisable to abstain from drinking before driving to prioritize safety.

The recommendations provided below serve as a general guideline for estimating the amount of alcohol that can be consumed before driving in Singapore. However, it is crucial to recognize that individuals’ reactions to alcohol can vary, and the information presented should be considered an approximate reference, as it may not apply to all.

The impact of body weight on blood alcohol levels is significant. BAC charts show that individuals with lower body weights typically have higher BAC levels.

For instance, a male weighing 160 pounds (72 kg) may reach a BAC of 0.02% after consuming a 12-ounce (350 ml) beer. In contrast, a woman who weighs the same and consumes the same amount of beer might have a BAC of 0.03%. This example illustrates the influence of gender on alcohol metabolism. Please refer to our BAC calculator for approximate calculations.

Limiting wine consumption to one or two glasses is advisable to maintain a BAC level within the legal alcohol limit in Singapore.

An average wine glass can hold around 142 milliliters (5 ounces) of liquid and generally has an alcohol by volume (ABV) of 12%.

If a male weighing 72 kilograms (160 pounds) drinks one glass of wine, his blood alcohol concentration may reach 0.02%. However, as explained earlier, factors like stress, an empty stomach, and medication usage can affect BAC levels.

Whether you have consumed only one beer or a small amount of wine, you must be aware of your blood alcohol level. If you are unsure about your driving ability, consider alternative transportation options.
