Ignition Interlock

Frequently Asked Questions

For more information see our main Ignition Interlock information page.

1) I have a motorcycle. Can I have an Ignition interlock device installed?
Yes. You may contact an Ignition Interlock Installer for installation requirements.

2) I have a Commercial Driver License (CDL). Am I eligible to obtain a SIIRDL?
Only drivers with a Class D or Class G driver license may be eligible for a SIIRDL under the new Arizona law.

3) Can someone use a balloon or other air source to mimic human breath?
No. Advanced Ignition Interlock technology includes sensors that detect and reject such samples – and prevent the vehicle from starting.

4) Will the ignition interlock device lose all memory if the battery is disconnected?
No. The device has a battery back up to protect the data log’s memory.

5) What if the driver is taking medicine with an alcohol base or recently used mouthwash?
During a training session provided by the installers, drivers are cautioned about common substances that contain alcohol, including mouthwashes and medications. If the blood alcohol concentration of the driver, as measured in the breath, is over the preset level, the driver will not be allowed to start the vehicle.

6) What happens when a driver fails the breath test?
The ignition interlock device will enter a lockout period for failed breath alcohol tests.

7) What happens when a vehicle equipped with an ignition interlock needs repair?
The driver needs to contact the Certified Ignition Interlock Device (CIID) provider before having repairs conducted, in case the repair shop has questions about the device. Documentation must be provided if the power to the vehicle is interrupted, as the device will record if the power is disconnected (i.e., battery change).
