Sober Steering Sensors May Replace Ignition Interlock Devices in OUI Cases

Guardian_Interlock_AMS2000_1Last month, I wrote about the use of ignition interlock devices in Massachusetts drunk driving cases. Under Melanie’s Law, courts may order repeat OUI offenders to install these mobile breathalyzers in their vehicles, at their own expense. The devices were originally hailed as an effective way to stop drunk driving, but as I wrote in January, citizens and Massachusetts OUI defense attorneys have raised significant questions about their effectiveness, reliability and safety.

Now, a report from the Record of Waterloo, Ontario, Canada suggests that ignition interlock devices may someday be outmoded by a new technology. The Feb. 12 article says Sober Steering Sensors Canada Inc. is developing a type of chemical sensor that can detect what it calls the gas byproducts of alcohol though a person’s skin. The company is developing a steering wheel that incorporates the sensors. As with IIDs, the system would not allow the vehicle to start if it detects a high BAC. The Record said the company is already testing the technology in “fleet” vehicles, including buses and large trucks. Both MADD and the auto insurance industry have expressed interest, and the company’s founder was slated to talk to Florida’s state legislature about the technology Feb. 15.

The article said Sober Steering’s product may improve on IIDs for several reasons. IIDs require a “clean” breath test before they allow the vehicle to start. Drivers can get around this by having another person take the test. For this reason, IIDs also require a “rolling retest,” which means retaking the breath test while the vehicle is in motion. Critics believe this is not safe, especially since the car can shut down in traffic if the driver can’t find a safe place to pull over and take the test. The Sober Steering technology can take rolling retests without the driver having to do anything but keep his or her hands on the wheel. Sober Steering claims its technology can tell the difference between alcohol consumption and alcohol from hand sanitizer, mouthwash or other products, a common criticism of breathalyzers. And the cost of installing it is a sixth to a tenth of the cost of an IID, the article said.

As a Massachusetts drunk driving criminal defense lawyer, I agree that this could solve some of the drawbacks of IIDs, though not all of them. (Drivers could still illegally borrow someone else’s car, for example.) But I believe states and provinces should take a hard look at the technology before rushing to adopt it. For example, how finely tuned is the technology? Can it tell when a driver is wearing gloves? Can it consistently distinguish between a legal BAC of 0.07 and an illegal 0.08? Serious flaws, like the well-documented problems with breathalyzers, could allow defendants to fight their cases. Another concern has to do with the constitutional right of defendants to face their accusers. In cases of drunk driving, the test device is generally considered the “accuser,” which has led to court cases, successful in some states, demanding that the source code behind breathalyzer machines be publicly released. If Sober Steering’s technology will be used in the United States, the company should release its technology to allow defendants to build the best possible defenses.
