Ignition Interlock Device

The Intoxalock is a state-of-the-art breath alcohol ignition interlock device that simply works by requiring your breath sample prior to starting your car and periodically as you are driving. If your breath sample contains an alcohol level below the acceptable level of .025, your car will be allowed to start.

Intoxalock is very safe because the device will not shut the vehicle off when
it is being driven. The Intoxalock utilizes state-of-the-art fuel cell technology allowing for the highest level of accuracy and precision. It has been certified
by an independent laboratory to meet or exceed all National Highway Transportation Safety Administration (NHTSA) standards.
