Texting while driving is dangerous. But a new report by Mothers Against Drunk Driving (MADD) shows that sometimes technology in cars is a good thing. Ignition interlock systems have prevented more than 1.77 million attempts at drunk driving since 1999.
Ignition interlock systems are wired into the vehicles of people who are convicted of drunk driving. In order to operate the vehicle, the person must blow into the device, and drivers with an illegal blood alcohol concentration (BAC) of .08 or higher are prevented from driving.
Since signing ignition interlock laws, Arizona has seen a reduction in drunk driving fatalities of 50 percent, and West Virginia has seen a reduction in drunk driving fatalities of 40 percent. However, not all states require drunk drivers to install ignition interlock systems. Members of MADD hope the report pressures legislators to pass laws that require ignition interlock devices for drunk driving offenders.
