Singapore enforces a strict legal drink-driving limit of 80 milligrams of alcohol per 100 millilitres of blood (0.08% BAC).
A breathalyser test measures a driver’s blood alcohol content (BAC) by analysing their breath. In Singapore, the legal breath alcohol limit is 35 micrograms of alcohol per 100 millilitres of breath, which corresponds to 80 milligrams per 100 millilitres of blood. Drivers suspected of being under the influence may be subjected to this test at roadblocks, routine traffic stops, or after an accident.
Can You Be Charged Below the Legal Limit?
Yes. Even if your BAC is within the legal limit, you can still be criminally charged if you appear to be driving erratically or unable to control your vehicle.
Blood Alcohol Levels and Their Effects
- Sober: 0.00% BAC
- Legally Intoxicated: 0.08% BAC
- Very Impaired: 0.08% – 0.40% BAC
- High Risk of Serious Complications: Above 0.40% BAC
How Much Can You Drink and Stay Under the Limit?
The amount of alcohol you can consume while remaining under the limit depends on several factors, including:
✔ Your weight, age, sex, and metabolism
✔ Whether you’ve eaten recently
✔ The type and amount of alcohol consumed
✔ Your stress levels
To stay safe and avoid penalties, it’s always best to avoid drinking if you plan to drive.
