Ignition interlock installers expect to see a bigger work load in the coming months with the crackdown on drunk drivers. Repeat violators and first time offenders with high blood alcohol levels will now be required to have ignition interlock devices installed in their vehicles. Local technicians say they expect to be busy installing these devices into vehicles. Channel 5's Terry Kovarik talked with one local comany that said one in every ten calls is for the request of a mobile installation or recalibration of the device, and that they average five installations per week. The company expects to see that number increase to twenty per week by the year's end.
