Drunk in a Parked Car: Is It DUI? Traffic Police Clarify the Myth (and What It Means for English Learners)

Recently, a topic has gone viral among drivers in Nantong (and across China): “If you drink and then lie down inside your car, is that considered drunk driving (DUI)?” Rumors and misunderstandings have spread online, prompting traffic police to issue an official clarification. Below is a clear, practical breakdown—plus a short English-learning section so you can explain the rules accurately in English.

1) The real question behind the myth
Many drivers assume: “The car isn’t moving, I’m just resting in the seat, so it can’t be drunk driving.” But the key legal issue is not whether the vehicle is moving—it’s whether the driver is in “driving” status and whether the driver’s behavior creates a realistic risk of operating the vehicle after drinking.

2) What traffic police actually clarified
The traffic police’s clarification (commonly in similar official notices) is essentially this:

• If you have been drinking and you are in the driver’s seat with the engine on (or the vehicle otherwise in a ready-to-drive state), you may be treated as being in a “driving” state and face DUI testing—even if the car is parked.
• If you are resting in the passenger seat or the back seat, with the engine off, and you have no intention and no action to drive, it is generally not treated as drunk driving. However, you should still avoid creating ambiguity—such as sitting in the driver’s seat with keys in the ignition.
• Simply “lying in the car to sleep it off” is not automatically a violation, but the facts matter: position (driver’s seat vs passenger seat), engine status, keys, and whether the vehicle could be readily operated.

3) Why people get confused: “parked” ≠ “safe”
The law focuses on risk control. Officers consider whether a drunk person has the ability to start and move the vehicle, even accidentally. Sitting in the driver’s seat with the engine running can make it easy for the vehicle to move—and that is exactly the danger the rules target.

4) Practical do’s and don’ts after drinking
Do:

- Use a designated driver, taxi, or ride-hailing service.
- If you must wait, sleep in the passenger/back seat, keep the engine off, and put the keys somewhere clearly out of reach.
- If you’re unsure, call a friend or ask staff at a nearby venue for help.
Don’t:

• Don’t sit in the driver’s seat “just to rest” after drinking.
• Don’t turn on the engine “for air conditioning” after drinking.
• Don’t argue with officers based on internet rumors; follow the on-site instructions and cooperate.

5) English micro-lesson: how to explain this to foreign friends or in an English test
Useful terms:

- drunk driving / DUI (Driving Under the Influence)
- traffic police
- parked car / engine on / engine off
- designated driver
- roadside breath test
Sample sentences:

- “Having drunk alcohol, sitting in the driver’s seat with the engine on can still be treated as DUI.”
- “If you plan to sleep in the car after drinking, sit in the passenger seat and turn the engine off.”
- “The safest choice is to use a designated driver or a taxi.”
Writing tip (for IELTS/TOEFL or practical emails):
State the rule clearly, give the reason (risk of the vehicle moving), and end with a safe recommendation. Example: “To avoid legal risk and ensure safety, drivers should never wait in the driver’s seat with the engine on after drinking; instead, they should arrange a designated driver.”

6) Bottom line
The clarification is simple: don’t rely on the “parked car” myth. After drinking, keep out of the driver’s seat, keep the engine off, and choose a safe way home. If you want to remember one English takeaway, memorize this: “Engine on + driver’s seat after drinking = high risk of being treated as DUI.” Safety first—on the road and in your English explanations.
