Anti-Drunk Driving Technology Raises Concerns About Surveillance

 Posted on June 12, 2026 in Criminal Defense

Lawmakers, law enforcement officials, vehicle manufacturers, and safety advocates have spent decades putting measures in place to prevent drunk driving. Across the United States, around 12,000 people are killed every year in car accidents involving drivers who were intoxicated. To try to reduce these numbers, laws have been passed that will require new technology to be used to prevent people from driving while they are intoxicated. However, this has raised concerns about privacy, surveillance, and other issues that may affect people’s rights.

As new technologies are developed and implemented, people who are facing criminal charges will need to understand how to protect their rights and address evidence gathered through digital surveillance. Whether a person is facing charges of DUI or has been charged with another crime due to data captured by a vehicle or another device, legal representation by a skilled attorney can be essential. A lawyer with experience addressing issues related to privacy and technology can provide guidance on how to address the digital evidence that may play a role in a criminal case.

Concerns Related to "Kill Switch" Technology and Digital Surveillance

In 2021, Congress passed the HALT Drunk Driving Act, which included a provision requiring all new vehicles to include advanced technology to prevent drunk driving. This technology may involve systems that monitor drivers and prevent a vehicle from operating if they determine that the driver is under the influence of alcohol or drugs or is otherwise impaired. While the law did not describe a "kill switch," this term has been used to describe the technology, since it would prevent a vehicle from starting or cause it to shut down if it detects alcohol intoxication or other forms of impairment.

The ways anti-drunk driving technology in vehicles may work has not yet been determined. The law requires this technology to be passive, so it cannot include devices that would require drivers to provide a breath sample. The solutions that have been proposed include technology that tracks a driver’s eye movements or monitors a driver in other ways to detect impairment. The National Highway Traffic Safety Administration (NHTSA) has not yet finalized any rules about what technology may be required, and it is unlikely that any rules will take effect until at least 2027.

Concerns have been raised about how anti-drunk driving technology will function and how it will affect people’s ability to use their vehicles. The ability of technology to detect impairment based on eye tracking is questionable, and false positives could prevent people from driving even when they are not intoxicated. There are also questions about how the data captured by these technologies will be used and stored and whether it may be accessible to law enforcement or others. Cars already capture a great deal of information about people’s movements, communications, and activities, and adding additional forms of surveillance could affect people’s privacy rights, especially when data could be used as evidence in criminal cases.

The issue of digital surveillance has received more attention recently due to concerns about vehicle kill switch technology, as well as increased scrutiny of the methods used by government officials to obtain people’s data and monitor their communications. Section 702 of the Foreign Intelligence Surveillance Act (FISA) provided the U.S. government with the ability to monitor non-U.S. citizens without the requirement to obtain warrants. Due to loopholes in this law, the government was also able to monitor communications between U.S. citizens and people in other countries. However, Congress has allowed Section 702 to expire, which may limit the government’s ability to perform digital surveillance and help protect people against violations of their rights.
