Illinois is only the second state to require the devices to be installed on cars of first-time offenders.
To drive home the point of drinking and driving dangers, a Springfield radio DJ volunteered to do a sobriety test.
"It's a sad, sad reality that you think you can do one thing, but the reality is that you have no idea what you can really do," said Bondsy, Springfield DJ.
If an offender is caught driving a car without the device, the offender could face felony charges with a minimum of 30 days in jail.
