Ignition interlock devices (IIDs) are easily the best way to prevent drunk driving. Connected to the ignition system on a car or motor vehicle, a driver has to submit a breath sample that measures blood alcohol concentration (BAC) in order to start the car. If the driver’s BAC is above the predetermined limit, the car will not start, preventing a person from driving drunk and keeping our roads safe.
Today, more people are considering voluntary ignition interlock device installation, including parents of young drivers. Some auto insurance companies offer discounts for teenage drivers with a voluntary IID installed in any vehicles driven. Since parents never want to answer the call that a child has been involved in a traffic accident, especially one that involves alcohol, a voluntary IID installation reduces the chance of a minor driving a vehicle after drinking. Plus, an IID can enforce the national “zero tolerance” policy toward alcohol and underage drinkers, and eliminate the chance of a felony DUI/DWI conviction that can affect a young driver for life.
Many companies are also choosing to install IIDs in company cars, vans and trucks due to the financial benefit where insurance and liability is concerned, but also a safety benefit for employees and customers. School districts and other organizations that transport adults and children are also considering voluntary IID installations in buses order to provide a level of security to passengers and to others on the road.
IID use is preventing repeat DUI/DWI offenses by around 67% overall, which is why more states are implementing strict IID penalties for drunk driving convictions. By initiating the installation of the device before an offense occurs, those same numbers can reflect even first-time drunk driving incidents, eliminating the chance of a person’s poor judgment after consuming alcohol.
