First DUI in Indiana? You may need an ignition interlock.

There’s no such thing as a mulligan when it comes to ignition interlock devices and DUI convictions in Indiana anymore. Indiana Governor Tom Wolf signed a bill that requires the installation of ignition interlock devices into the vehicles of those convicted of a first driving under the influence (DUI).

The law is scheduled to go into effect in September of 2017.

What is an ignition interlock device?

An ignition interlock device is, basically, a machine that is attached to the ignition of a vehicle. Before the vehicle can start, the driver must provide a breath sample. The machine then analyzes the breath sample. If alcohol is present, the vehicle will not start. If no alcohol is detected, the vehicle will start.

In some devices, retesting occurs while the driver is operating the vehicle. This is intended to reduce the risk of another person providing the initial breath sample to start the car for the driver.

Generally, the installation and maintenance costs are the responsibility of the driver.

How does this law change things?

Originally, a first time DUI offense would receive various penalties, but mandatory installation of an ignition interlock device was not one of them. This law requires its installation if the driver had a blood alcohol concentration at or above 0.10.
