Uber Patent Technology Drunk? Explained

Yes, Uber has patented technology related to detecting drunk driving, but it is not a breathalyzer and it does not automatically report you to the police. The patent, filed in 2016 and granted in 2019, describes a system that uses your smartphone’s sensors to detect likely impairment and then adjust your Uber experience—for example, by changing how it matches you with drivers or by showing you a sobriety test. Here is what the patent actually covers, how it works, and why it matters for riders.

Background: Why Uber Filed This Patent

Uber’s patent application, titled “Detecting and assessing impairment,” was filed in 2016 and granted in 2019. It was part of a broader push to improve safety after a series of high-profile incidents involving drivers and riders. The patent describes using the sensors already in a smartphone—accelerometer, gyroscope, GPS, and even the camera—to build a “user profile” of normal behavior, then detect deviations that might indicate intoxication.

The patent is not a product announcement. Many companies file patents defensively or as part of research, and most never become a feature. However, the existence of this patent shows that Uber has seriously considered how to use phone data to address drunk riding—both for riders and for drivers.

How the Technology Would Work

According to the patent, the system would collect data from your phone’s sensors before and during a trip. It would look for patterns such as:

• Unusual walking gait when you approach the pickup point (detected via accelerometer).
• Slower reaction times when you interact with the app (e.g., typing or tapping).
• Changes in how you hold the phone or how often you drop it.
• GPS data showing erratic movement or walking in circles.

If the system flags a high probability of impairment, the patent suggests several possible responses:

• Send a message asking the rider to confirm they are okay.
• Offer a “selfie” or a short reaction test within the app.
• Adjust the ride experience—for example, ensuring the driver knows the rider may need help.
• In extreme cases, refuse the ride or contact emergency services.

The patent also covers detecting impairment in drivers, using similar sensor data from the driver’s phone while they are driving.

What the Patent Does NOT Do

A common misconception is that the patent involves a breathalyzer or blood-alcohol measurement. It does not. The patent explicitly avoids any chemical test; it relies solely on indirect behavioral signals. It also does not automatically call the police. The patent describes a “server” that would evaluate the data and choose a response, but that response is not specified as a law-enforcement report. In practice, any such system would have to comply with privacy laws and would likely require user consent.

Another misconception is that the technology is already active. As of now, Uber has not publicly deployed this specific feature. The company has stated that it uses various safety tools, but the patent is a legal document, not a product roadmap.

Privacy and Ethical Concerns

Using smartphone sensors to infer intoxication raises significant privacy questions. The patent describes collecting data continuously, including when the app is in the background. That could include sensitive information about your location, movement, and even who you are with (via microphone, though the patent does not emphasize audio).

There is also the risk of false positives. A person with a limp, a neurological condition, or simply a bad phone grip could be flagged as impaired. The patent acknowledges this by suggesting the system would build a baseline profile for each user, but that does not eliminate the risk of discrimination or embarrassment.

Legal experts note that such a system could conflict with disability laws if it disproportionately affects people with movement disorders. Uber would need to ensure the system is transparent and allows users to appeal or opt out.

Comparison to Other Drunk-Detection Technologies

Uber’s approach is not the only one. Several automakers and tech companies have explored similar ideas:

• Driver monitoring cameras – Some cars use cameras to track eye movement and head position to detect drowsiness or distraction (e.g., Cadillac Super Cruise, Tesla’s cabin camera). These are more direct but require hardware in the vehicle.
• Alcohol detection systems – The Driver Alcohol Detection System for Safety (DADSS) uses touch-based or breath-based sensors built into the car to measure blood alcohol content. This is a chemical test, unlike Uber’s approach.
• Phone-based apps – Apps like “AlcoDroid” let users log their drinks and estimate BAC, but they rely on user input, not automatic sensing.

Uber’s patent is unique in that it would work with the phone you already have, without any additional hardware, and it would be integrated into the ride-hailing service itself.

What It Means for Riders and Drivers

If Uber ever implements this technology, riders might notice subtle changes:

• You might receive a prompt to “confirm you’re okay” before a ride if the app detects unusual movement.
• Drivers might see a note that the rider may need extra assistance.
• In extreme cases, a rider could be denied a trip—though that would likely be a last resort.

For drivers, the system could monitor driving smoothness and alert them to pull over if they appear impaired. This could reduce accidents, but it also raises concerns about surveillance and job security.

The key takeaway is that the technology is still theoretical. Uber has not announced any rollout, and patents often expire without being used. However, the patent signals that Uber is thinking about how to use data to solve a real safety problem—and that future rides could involve more than just a tap and a ride.

Frequently Asked Questions

Does Uber actually use this patent today?

No. As of now, Uber has not publicly deployed the technology described in the patent. The patent was granted in 2019, but there is no evidence it is in use. Uber continues to use other safety features like GPS tracking and emergency buttons, but not sensor-based impairment detection.

Can Uber detect if I’m drunk from my phone?

Not currently. The patent describes a system that could do this, but it is not implemented. If it were, it would rely on motion sensors and typing patterns, not a breathalyzer. It would also need your consent and would likely be subject to privacy regulations.

Will Uber refuse to give me a ride if I’m drunk?

Today, Uber does not systematically refuse drunk riders. The patent suggests that a future system might deny trips in extreme cases, but that would be a significant policy change. Currently, drivers can refuse a rider if they feel unsafe, but that is a driver decision, not an automated one.

Is the patent about detecting drunk drivers or drunk riders?

Both. The patent covers detecting impairment in both riders and drivers. For drivers, it would monitor driving behavior; for riders, it would monitor walking and phone interaction. The same sensor data could be used for both.

What happens if the system makes a mistake?

That is a major concern. The patent acknowledges the need for a baseline profile, but false positives are still possible. If a rider is wrongly flagged, they might be denied a ride or asked to take a test. Uber would need to provide a way to appeal or override the decision.

Is this legal under privacy laws?

It would depend on how it is implemented. Collecting sensor data requires user consent under laws like GDPR and CCPA. Uber would need to disclose what data is collected and allow users to opt out. The patent does not address legal compliance, but any real deployment would have to.
