What are ignition interlock devices?

Ignition interlock devices are a requirement that individuals accused of driving while under the influence may face. Because of the impact and costs associated with having an ignition interlock device on your vehicle, accused drivers facing DUI charges should be familiar with how ignition interlock devices work.

An ignition interlock device is essentially a breathalyzer device installed on the vehicle of a driver who has been convicted of DUI charges. Ignition interlock devices are one of the potential penalties and consequences a drunk driver faces. An accused driver facing DUI charges may be required to install an ignition interlock device on their vehicle at their own expense. The driver is usually required to pay the costs of an ignition interlock device which can be costly especially on top of the fines and fees commonly associated with DUI charges.

Ignition interlock devices are designed to prevent a driver from being able to operate their car if alcohol is measured on the driver's breath. An ignition interlock device disables the ignition if alcohol is detected on the driver's breath. The driver will be required to blow into the ignition interlock device to start their vehicle and, if alcohol is measured on their breath, they will be prevented from starting the vehicle. There is typically a lock-out period during which time the driver will be prevented from starting the vehicle following a failed test.

The requirement to install an ignition interlock device is one of several penalties and consequences accused drivers may face which is why they should know how to respond to DUI charges if they find themselves facing them. Criminal defense rights and options apply to DUI charges so accused individuals should know how to prepare their defense.
