Drunk driving remains one of the leading causes of road deaths in Hawaii. According to Hawaii Health Matters, 32.3% of fatalities involve DUI. Despite public safety campaigns and legal limits, alcohol impaired driving continues to take lives and cause serious injuries.
Thanks to laws like the bipartisan infrastructure law, the federal government is pushing automakers to include alcohol detection systems in newly manufactured vehicles. These systems are meant to prevent drunk driving accidents before they happen. Cars can now use sensors, cameras, and other tools to check if a driver is impaired, such as having a high blood alcohol level or showing unusual driving behavior. Technology alone will not solve the problem, but it could be an important step in lowering drunk driving accidents. With the right systems, lives can be saved and crashes reduced.
As legal professionals at Recovery Law Center, we often work with people hurt by drunk drivers. The question many now ask is: can technology in cars sense a drunk driver? The answer is yes, and the technology is improving fast. With new passenger vehicles rolling out every year, features that detect a drunk driver are beginning to appear.
How Alcohol Detection Technology Works in Cars
Modern cars are being built with detection systems designed to measure a driver’s condition before and during travel. These systems can identify if a person behind the wheel is drunk by using different types of alcohol detection. One type uses infrared light to measure alcohol in a driver’s breath without needing them to blow into a device. Another type is touch-based and uses sensors on the steering wheel or ignition system to detect blood alcohol content through the skin.
The driver alcohol detection system doesn’t ask the driver to take any action. It works quietly and automatically, which helps prevent delays or resistance. Once alcohol is detected, the system can disable the ignition system, stopping the vehicle from starting. This level of automation is what separates today’s systems from older interlock devices.
The DADSS program, a public-private partnership, is behind much of this research. It focuses on building technology that can prevent impaired driving through passive monitoring. This means drivers won’t notice the test happening. These systems aim to prevent drunk driving crashes without adding steps for the driver. If the legal limit is reached or passed, the vehicle won’t move.
Limitations and Challenges of Detection Technology
Although these systems show promise, they also raise concerns. One issue is false positives. A detection system might stop a sober driver from operating a car if the sensors misread their condition. For example, using hand sanitizer before touching the steering wheel could confuse a touch sensor. These kinds of errors are being worked on, but they remain a concern.
Another challenge is cost. While newer cars will likely include detection tools, millions of older vehicles won’t. This creates a gap between those who can afford new cars and those who can’t. Drunk driving is not limited by income, so leaving out large groups of drivers may weaken the impact.
Another issue is who can access the data from these systems. People have raised privacy concerns. If alcohol levels are found, will the information go to law enforcement, insurance companies, or stay private? These rules are still being decided. Prevention matters, but it should be balanced with driver rights and fair use of the technology.
The Role of DADSS and Public-Private Partnerships
The Driver Alcohol Detection System for Safety, or DADSS, has been a driving force behind the development of impaired driving prevention technology. It is a public-private partnership between automakers and the federal government, designed to create safety tools that can be used in real cars. Unlike ignition interlocks used for people with prior DUI convictions, DADSS aims to use passive systems that require no effort from the driver.
These systems are being developed to test for alcohol levels in real time without requiring the driver to stop or interact with the equipment. Using advanced sensors and cameras, the system can check for alcohol in the breath or skin, and if the driver’s blood alcohol content is above the legal limit, the car stays off.
DADSS is also testing its systems with real families and professional drivers to ensure accuracy. This includes measuring system reliability in a range of weather and driving conditions. The goal is for detection technology to be added to all new cars without affecting driver comfort or experience. As these systems improve, more companies, including trucking companies, are watching closely, knowing the benefit of stopping drunk drivers before a trip even begins.
How This Affects Drivers and Road Safety
Once these systems are in place in all new vehicles, the landscape of road safety may shift. Today, law enforcement, road signs, and personal responsibility are the primary tools used to prevent drunk driving. But with detection systems built into cars, vehicles themselves will take an active role. Drivers won’t be able to start the car if alcohol is detected, and alerts may sound if someone shows signs of impairment while driving.
This technology is also being tested in autonomous vehicles, where systems need to take control if a human driver becomes impaired or unresponsive. These vehicles are learning to detect when the person in the driver’s seat is unsafe, using:
- Behavior patterns
- Touch sensors
- Eye tracking
For parents and employers, these systems offer peace of mind. It gives families a new way to protect loved ones from alcohol related crashes. For drivers of commercial or trucking vehicles, it provides added safety and helps prevent legal consequences from impaired driving. Over time, this could lead to fewer deaths, fewer crashes, and fewer people hurt by drunk drivers.
What Recovery Law Center Wants You to Know
At Recovery Law Center, we often represent victims injured in drunk driving crashes. Every crash involving a drunk driver is preventable, and we believe that drivers, carmakers, and lawmakers each have a role to play in improving road safety. While detection systems are not perfect, they offer a new way to stop drunk driving before it happens.
If you or someone you care about was hurt in a crash where alcohol played a role, our team can help you understand your legal options. Whether the driver was impaired or a system failed to stop them, you may be entitled to compensation for medical costs, missed work, and long-term effects.
The future of transportation is changing. Detection technology might soon be in every car, helping to prevent drunk driving from ever happening. But until then, the law remains clear: if someone drives drunk and causes harm, they are responsible. At Recovery Law Center, we’re here to support those affected by drunk drivers and hold the right people accountable.
