vehicle driven by a drunk driver. North Carolina A conviction of Driving While Impaired with a blood alcohol concentration of 0.15 or more or another conviction within the past seven years will require an ignition interlock device to be installed on the vehicle. Texas As of Sept 1, 2015, anyone arrested for driving over the legal limit of .08% can opt for an IID restriction rather than wait for their driver's license suspension period to be up. For BAC levels .15% and over, Texas courts require IIDs, even for first time offenders. Utah Effective July 2, 2009, anyone convicted of a DUI, whether it be a first offense or a subsequent offense, will be required to have an ignition interlock device placed on their car — for 18 months for first time offense. Virginia Effective July 1, 2012, anyone who is convicted of DUI may drive only with an ignition interlock after the first offense, as a condition of a restricted license and is required to have an ignition interlock installed in each vehicle owned by or registered to him after a second offense for a period of six months. The bill also provides that the court may authorize a restricted license for travel to and from the interlock installer and a person can pre-qualify for an ignition interlock prior to conviction. Washington First-time DUI convictions result in one year of a mandatory ignition interlock device. A second conviction requires the IID be installed for at least five years, and on a third offense or greater, the requirement becomes at least ten years. Some convictions of negligent driving or reckless driving can require the convicted person to use an IID for a period of six months or longer. Universal IID installation Proposals have been made to install IIDs on all new vehicles, set to the legal limit for the driver. Some politicians in Sweden, Japan, Canada, the US, and other countries have called for such devices to be installed as standard equipment in all motor vehicles sold. Issues to be solved, besides consumer and voter acceptance, include difficulty in obtaining accurate measurements without inconvenience, and a need to achieve high reliability, in order not to interfere with vehicle usability.
