Non-Alcoholic Beer and Driving: The Legal Answer

You can legally drive after drinking non-alcoholic beer in all 50 states. Non-alcoholic beer contains less than 0.5% alcohol by volume (ABV), which is below the threshold that federal law recognizes as alcoholic. A single can or bottle will not raise your blood alcohol content (BAC) to a measurable level, and it will not impair your ability to drive.

However, the legal answer and the practical answer are not always the same. A police officer who sees you with a beer can—even a non-alcoholic one—may still stop you. How you handle that stop, and what you say, matters more than what you actually drank.

Key Takeaways

  • Non-alcoholic beer is legal to drink and drive because it contains less than 0.5% ABV and will not raise your BAC.
  • A police officer can still stop you for an open container violation if the can is open in your vehicle, regardless of alcohol content.
  • If you are stopped, do not volunteer information about what you were drinking—let the officer ask, and answer only what they ask.
  • A breathalyzer test will show your true BAC; non-alcoholic beer will not produce a positive result on a calibrated device.
  • Keeping non-alcoholic beer sealed and out of reach while driving removes the legal risk entirely.

Why Non-Alcoholic Beer Does Not Impair You

The 0.5% ABV threshold exists because that amount of alcohol is too small to affect your central nervous system or your motor control. To put this in perspective: a standard 12-ounce beer contains about 5% ABV, which means roughly 0.6 ounces of pure alcohol. A 12-ounce non-alcoholic beer contains about 0.06 ounces of pure alcohol—one-tenth as much.

Your liver processes alcohol at a rate of roughly one standard drink per hour. A single non-alcoholic beer would contribute so little to your BAC that it would be undetectable on a breathalyzer. Even if you drank five non-alcoholic beers in a row, your BAC would remain below 0.01%—far below the legal driving limit of 0.08% in every state.

Open Container Laws and Non-Alcoholic Beer

Open container laws in most states do not distinguish between alcoholic and non-alcoholic beverages. If the can or bottle is open and accessible to the driver or passengers, you can be cited for an open container violation—even if it contains non-alcoholic beer. The violation is about the open container itself, not the alcohol content.

The safest approach is to treat non-alcoholic beer the same way you would treat any beverage while driving: keep it sealed, store it in the trunk or back seat, and do not open it until you have parked. This removes any ambiguity and protects you from a traffic stop based on what an officer sees.

What Happens If You Are Stopped

If a police officer stops you and sees a non-alcoholic beer can, they may ask what you were drinking. You are not required to volunteer this information, but you are required to answer direct questions truthfully. If the officer asks, "What were you drinking?" you can say "non-alcoholic beer" or straightforward "a beer"—both are accurate.

The officer may ask you to perform a field sobriety test (the walk-and-turn, one-leg stand, or horizontal gaze nystagmus test). These tests measure coordination and balance, not alcohol content. If you are not impaired, you should perform them without difficulty. You can decline these tests, though doing so may give the officer reason to request a breathalyzer.

A breathalyzer will show your actual BAC. If you have only consumed non-alcoholic beer, the result will be 0.00% or close to it. This result ends the investigation when ready—the officer has no legal basis to arrest you for impaired driving.

The Perception Problem

The real risk of drinking non-alcoholic beer while driving is not legal—it is perceptual. An officer who sees you with a beer can has no way to know it is non-alcoholic without asking or testing you. If you are also driving erratically, speeding, or swerving, the officer will assume you are impaired and will stop you to investigate.

This is not unfair; it is how traffic enforcement works. Officers cannot read labels from a distance. They respond to behavior—how you are driving—not to what you are drinking. If your driving is safe and attentive, an officer has no reason to stop you in the first place, regardless of what beverage is in your car.

Why Some People Worry About Non-Alcoholic Beer and Driving

The concern often comes from a misunderstanding of how breathalyzers work or from confusion about what "non-alcoholic" means. Some people believe that non-alcoholic beer contains zero alcohol, which is not true—it contains a small amount. Others worry that the fermentation process or the way non-alcoholic beer is made might somehow affect a breathalyzer result differently than other beverages.

Breathalyzers measure the concentration of ethanol (the type of alcohol in beer, wine, and spirits) in your breath. They do not care where the ethanol came from or how it got there. A breathalyzer calibrated to legal standards will accurately measure your BAC whether you drank regular beer, non-alcoholic beer, or nothing at all. The amount of ethanol in non-alcoholic beer is so small that it will not register on a breathalyzer in any meaningful way.

Best Practices for Driving with Non-Alcoholic Beer

If you want to avoid any legal or perceptual issues, follow these steps: keep all beverages—alcoholic or non-alcoholic—sealed while the vehicle is in motion. Store sealed cans or bottles in the trunk, not on the seat or in cup holders where they are visible. Do not open any beverage until you have parked and turned off the engine.

If you are the driver, do not drink anything from an open container while driving, even water or soda. This keeps your hands on the wheel and your attention on the road. If you are a passenger, you can drink non-alcoholic beer from an open container in most states (check your local open container law), but the driver should not.

These practices protect you from open container citations, from officer suspicion, and from distraction. They also model safe driving behavior for anyone else in the vehicle.

Frequently Asked Questions

Will a breathalyzer show a positive result if I drink non-alcoholic beer?

No. A calibrated breathalyzer will show a BAC of 0.00% or very close to it after non-alcoholic beer. The amount of ethanol is too small to register. If a breathalyzer shows a positive result, it means you consumed something with measurable alcohol content, or the device needs calibration.

Can I get a DUI for drinking non-alcoholic beer?

You cannot be convicted of DUI based solely on drinking non-alcoholic beer, because your BAC will not be elevated. However, you could be arrested if you are visibly impaired from another cause (medication, fatigue, or a medical condition) and an officer believes you are impaired by alcohol. A breathalyzer test would clear you when ready.

Is it illegal to have an open non-alcoholic beer in my car?

Most states have open container laws that explore to any beverage in an open container, regardless of alcohol content. The safest approach is to keep all beverages sealed while driving. Check your state's specific open container law, as some states may have exceptions for non-alcoholic beverages.

What should I tell a police officer if they ask what I was drinking?

Tell the truth. If you were drinking non-alcoholic beer, say so. You do not need to volunteer information, but you must answer direct questions honestly. A truthful answer, combined with a clean breathalyzer result, will end the investigation.

Can I drink non-alcoholic beer and then drive when ready?

Yes. Non-alcoholic beer will not raise your BAC or impair your driving ability. There is no waiting period required. However, keep the can sealed while driving, and do not open it until you have parked.
