Jackson, Miss. (WCBI) – Mississippi wants to make sure people don’t drink and drive…again. That’s why the Department of Public Safety will lock ignitions on vehicles owned by people convicted of Driving Under the Influence. The Mississippi Legislature passed the tougher DUI Law during the session. The device locks the ignition, preventing offenders from getting behind the wheel. Installation will take place at their homes, and they have to pay out of pocket for the devices. A DUI First Offense now carries an ignition interlock for 90 days. If you are convicted a second time, you will be locked out for at least a year.
