What is the legal limit for drunk driving in milliliters?

[BriellaDella]

The legal limit for drunk driving is when a driver's blood alcohol content (BAC) is greater than or equal to 20 milligrams per 100 milliliters of blood, but less than 80 milligrams per 100 milliliters, which is considered driving after drinking. A BAC of 80 milligrams or more per 100 milliliters is classified as drunk driving. For drunk driving, the traffic management department of the public security authority will restrain the driver until sober, revoke the motor vehicle driving license, and pursue criminal liability according to the law. The driver will not be allowed to re-obtain a motor vehicle driving license within five years. For driving a commercial motor vehicle after drinking, the penalty is 15 days of detention, a fine, revocation of the motor vehicle driving license, and prohibition from re-obtaining a motor vehicle driving license within five years.

After the last dinner, I specifically looked this up. In our country, the standard for drunk driving is a blood alcohol content of 20mg/100ml. For example, drinking half a bottle of beer could exceed the limit. Once, my friend took just two sips of rice wine before driving and was caught. The breathalyzer test showed 35mg, resulting in a six-month license suspension and a 2000 yuan fine. If it reaches 80mg, it's considered drunk driving, which is a criminal offense that can land you in jail. Important reminder: now, drunk driving also applies to electric vehicles and motorcycles—don't take any chances. Moreover, if a driver on probation is caught drunk driving, their license will be revoked immediately, and they'll have to start all over again.

I remember when I took my child to the parent-teacher meeting, traffic police came to the school to educate us. Driving with a blood alcohol level exceeding 20mg/100ml is considered drunk driving, which is roughly equivalent to one paper cup of beer. The officers demonstrated the breathalyzer and said on-site readings of 35mg would be treated as drunk driving. They especially emphasized that parents picking up children need to be extra vigilant, as many accidents on weekend evenings are caused by driving after drinking small amounts at dinner. They specifically mentioned that 'overnight alcohol' also counts, and they often catch hungover drivers during early morning checks.

Seriously, you must never cross the 20mg/100ml limit. Last year, our team's Old Zhang had some rice wine at dinner and thought he'd be fine after three hours, but ended up rear-ending someone on the road. Blood tests showed 43mg, so the insurance didn't cover a penny, and he had to pay out of pocket for the other car's repairs. Do the math: license suspended for six months, affecting his transport business, a 2,000-yuan fine, retaking the theory test, not to mention lost wages. If it had been drunk driving, he'd have lost his job outright, with a criminal record affecting even his kids' background checks for government jobs.

From a detection perspective, the breath alcohol tester used by traffic police triggers a drunk driving charge at 20mg/100ml (approximately equivalent to 0.1mg/L breath alcohol concentration). Many people are unaware of how sensitive this threshold is: just half a bottle of fruit beer or half a tael of liquor can exceed the limit. Special reminder for those taking medication: Huoxiang Zhengqi Shui (a traditional Chinese medicine) or mouthwash may cause false positives, but there's no denying it if alcohol was truly consumed. Blood tests require venous blood sampling for verification, which has smaller margin of error. Recent new regulations also state that insurance companies can reclaim advanced medical payments for accidents caused by drunk driving.

A common misconception during duty is drivers saying 'just one drink is fine'. In fact, the 20mg standard is quite strict—even the last sip left at the bottom of a beer glass can exceed the limit. There was a real case where a driver was penalized after eating drunken shrimp and blowing 26mg. What's more important to note is that even moving the car counts as driving. Last week, a driver was caught moving their car in an underground garage—just 30 meters—and was reported. The advice is: if you've been drinking, don't even touch the car keys. Nowadays, hiring a designated driver is very convenient.
