Chapter 9-4 Ignition Interlock Devices (IID) Minimum Vehicle Requirements and Use continued If you fail a second time within a service period, your vehicle will go into lockout and you will need to visit your service provider within 48 hours to continue operating of the vehicle. A service period is the 1-30 day period following the last IID calibration or service visit. * Step 3 - After the vehicle has started, you will be required to take rolling re-tests at random intervals while operating the vehicle. When it is time to take a rolling re-test, the IID will beep, alerting the operator that they have five minutes to take the breath-alcohol re-test. * Step 4 - You may take the rolling re-tests while driving, but it is recommended that, if it is safe to do so, you pull your vehicle over to the side of the road and take the breath-alcohol re-tests. If you do not take the rolling re-test, or if you turn the ignition off before taking the rolling re-test,. this will be considered a missed test. Please Note: The IID will never shut your engine off after it has been started. 06/16 9:64
