How long do you have to have a breathalyzer in your car after a dui?

The length of time you are required to have a breathalyzer, also known as an ignition interlock device (IID), in your car after a DUI varies depending on the state in which you live and the severity of your offense. In some states, a first time offender may be required to have an IID for a minimum of 6 months to a year, while repeat offenders may be required to have the device for several years or permanently. It is important to check with your state’s laws and your sentencing requirements to determine the exact length of time you will be required to have a breathalyzer in your car after a DUI.
