[Car Tips] Hong Kong Drink Driving Laws and Penalties

🍺 Editor's opening remarks

Honestly, I'm a beer buff myself, but drink driving is a definite red line in Hong Kong. Just how strict are Hong Kong's drink-driving laws? Simply put, even if you say, "I had half a glass of wine," you could be caught. The law doesn't rely on whether you're drunk or not, but on whether your blood/breath alcohol concentration is above the legal limit.

In Hong Kong, drinking and driving isn't just a common traffic violation; it's a criminal offense, leaving a criminal record and potentially punishable by immediate license suspension , hefty fines , imprisonment , and mandatory driver improvement courses . I've seen drivers fired from their jobs because their first offense was drinking and driving.

📜 1. Legal Background and Definition

According to Section 39 of the Road Traffic Ordinance (Cap. 374), drink driving includes:

1. Driving under the influence of alcohol : No blood test is required, as long as you can prove that your judgment and safe driving ability were impaired by alcohol at the time of driving.
2. Driving with an alcohol content exceeding the legal limit : If the alcohol content is detected by an instrument, you will be convicted even if there is nothing unusual in your driving.

📏 2. Legal limit of alcohol content (Hong Kong)

⚠️ Editor's note: These numbers aren't about "a few drinks" because they depend on your weight, gender, drinking speed, food intake , etc. Even a skinny guy might go over the limit with just one beer.

👮 3. Police testing process (Drink Driving Test)

(1) Inspection

• Traffic accident scene
• Routine roadblock inspections (especially on holidays and weekend nights)
• There is reasonable suspicion that the driver is under the influence of alcohol (driving erratically, swerving lanes)

(2) Rapid screening

• Wearing a portable preliminary breath tester (PBT)
• The driver blows into the mouth of the machine → If the test result is “negative”, the driver is allowed to go; if the test result is “positive”, the driver is taken back to the police station for further testing.

(3) Formal Evidence Instrument Testing

• Use the legally approved Evidential Breath Analyser
• Exhale twice → take the lower reading
• Or blood draw/urinalysis (performed in hospital/clinic)

(4) Arrest and bail

• Charged almost immediately, the driver was released on bail pending court appearance.
• The vehicle may be detained for inspection on the spot

🚨 5. The doubled consequences of dangerous driving/accidents caused by drunk driving

If the drink-driving offense also constitutes "dangerous driving" or "causing serious injury or death to another person", the penalty will be doubled:

• Dangerous driving causing death: Up to 10 years' imprisonment + lifetime license suspension
• Dangerous driving causing serious injury: up to 7 years' imprisonment
• Additional civil liability (insurance company may refuse to pay)

---

📑 6. Revocation and Relisting Requirements

1. After the tag expires
   • You must reapply for the driving test (theoretical + road test, sometimes even the license plate test)
   • Must complete a government-approved "Driving Improvement Course"📝
2. High-risk drivers (e.g., repeated drink-driving convictions): The court may impose psychological or alcohol counseling requirements

🪤 7. Common Ambush I've Seen

1. "I gotta have a drink" mentality
   • Poor physical fitness will lead to rapid excess
2. After a few hours, I thought the wine had faded
   • The time it takes to metabolize alcohol varies from person to person, and levels may still exceed the recommended limit 6-8 hours after drinking.
3. "I don't want to go back home, I just want to move the car."
   • The distance traveled is irrelevant and it is still considered driving behavior.
4. chewing gum/using mouthwash to think "er machine"
   • The machine that detects blood alcohol concentration is completely useless.
5. I thought it was okay to refuse to blow
   • Refusing a breathalyzer test is a criminal offense in itself, with penalties equal to or greater than those for drunk driving.

📌 8. Editor's Tips for Avoiding Pitfalls (Maintaining Zero Risk)

• Don't drive after drinking → The safest way is to not gamble
• Find a designated driver, call a taxi, or use a shared car service in advance
• If you can't drink casually but may be attending a social event → drink soft drinks/non-alcoholic beverages throughout the meal
• Talk to your friends/company and ask your designated driver to abstain from alcohol all night.
• If you have to drink → Leave your car in a safe place and pick it up the next day

🎯 Editor's Conclusion

Hong Kong's drink-driving laws are among the strictest in Asia. They affect not only your own life and license plate, but also the lives of passengers, pedestrians, and other drivers. I sincerely advise against drinking and driving simultaneously . Even if you're sober and your car's readings are accurate, it's useless to claim "I'm not drunk" if you can't explain it.

Once convicted, the consequences are far-reaching: a criminal record, a long-term license suspension, work restrictions, insurance premium increases, and social repercussions. The simplest and most practical solution is to avoid driving if you can, and avoid drinking if you can.
