It’s sometimes called a “rolling retest,” but that’s not the right term. Ignition Interlock clients shouldn’t be rolling at all, because it could potentially put them in danger.
When prompted for an Ignition Interlock random retest:
- Pull off the road safely into an area without traffic.
- Put the car in park, but don’t turn it off.
- Provide an Ignition Interlock breath sample.
Your car will never turn off during an Ignition Interlock random retest, no matter what the result.
