According to the USA Today, 11 states now require all people convicted of first time DUI / Drunk Driving to install ignition interlock devices. The US Congress may take up this issue this fall that will mandate states require all people convicted of first time DUI / Drunk Driving to install the devices in order to receive Federal Highway Funds. Any state that does not meet this requirement risks losing Federal Highway Funds. Reportedly, if all states meet the requirement, then there will be nearly 1 million ignition interlock devices installed in the US each year. If each device costs $350 to install and maintain, that translates into $350,000,000 for the ignition interlock device industry!
