CST Holdings

CST Holdings was founded in Iowa in 1988. Founders worked with scientific researchers at Iowa State University to develop alcohol-specific fuel cell technology, which made it possible to create devices that could extrapolate blood alcohol content (BAC) from a breathalyzer device. These devices are installed and synced with the vehicle’s ignition to prevent drunk driving.

CST Holdings is the parent company of Intoxalock, which provides ignition interlock devices (IID) and services to customers across the country. The company also works closely with insurance partner Breath Easy. IIDs are required for DUI offenders in some states to regain driving privileges. CST’s Intoxalock is the largest provider of IIDs in the country, and features more locations than any other IID provider as well as 24/7 customer support for drivers.

Our representatives help each customer through the process and are there every step of the way, and have been recognized for top-notch customer support.
