Will an ignition interlock device shut down the cars engine if the driver fails to perform a rolling retest when prompted?
A- No. Smart Start ignition interlock devices can only prevent a car from starting if the driver fails the initial breath test. If the driver becomes stranded and believes the ignition interlock is causing a problem, the unit may be able to self-diagnose and indicate the problem with the service light. The driver can also call the nearest Smart Start service center for help.
