Ignition Interlock Device Bond Condition: When it is Required and When it is Optional


During the 2019 legislative session, a change was made to when a magistrate is required to order an ignition interlock device (IID) as a bond condition. For the offense of DWI with a Child Passenger (the elements of this offense can be found in Section 49.045 of the Penal Code), the IID condition used to only be required if it was a subsequent offense. Now, this condition is required for this offense whether it is a first or subsequent offense. This new law applies to a defendant released on bond on or after 9/1/19 even if the offense was committed before then.

Below is a chart summarizing the current law for when a magistrate must impose an IID bond condition and when it is up to the discretion of the magistrate to decide whether or not to impose it. In the chart, CCP stands for Code of Criminal Procedure, PC stands for Penal Code, and DWI stands for Driving While Intoxicated.
