WINNIPEG -- Anyone convicted of impaired driving in Manitoba will have to have an ignition interlock device on their vehicle if they wish to drive legally.

Justice Minister Andrew Swan said Thursday that the new rule comes into effect on Saturday and will include first-time offenders.

Mandatory ignition interlock program currently applies to drivers who are granted conditional licensing during an active alcohol-related suspension, repeat convicted offenders or first offences with aggravating factors.

Mothers Against Drunk Driving Canada says it fully supports Manitoba's tough stand against drinking drivers.

The mandatory ignition interlock term lengths are one year for the first and second convictions, three years for a third and lifetime for the fourth and subsequent convictions.
