Ignition interlock devices (IID) are ordered by Wyoming courts in certain driving under the influence (DUI) cases. IIDs are connected to the vehicle’s ignition system and require the offender to submit a breath sample prior to starting the vehicle. If the device detects a breath alcohol content that is higher than a pre-set limit, the vehicle will not start. While the offender is operating the vehicle, the IID alerts the offender to submit a breath sample. These “rolling re-tests” are conducted at random times and are mandatory. Offenders must obtain IIDs from service providers that are approved by the State of Wyoming such as Lifesafer Ignition Interlock.
The offender is required to have the IID serviced by the service provider at the frequency specified by the service provider. During the service appointment, the service provider calibrates the IID. The device is inspected for proper operation and evidence of tampering, circumventing or attempts to remove the device. The service provider downloads the data from the IID and reports the data to the Wyoming Department of Transportation (DOT) and the courts. Any violations of the IID requirement result in additional legal actions.
The IID restriction period is determined by the court depending on the circumstances of the DUI offense and the offender’s record of prior DUI convictions. For first-time DUI convictions with a blood alcohol content of 0.15 or higher, the IID is required for a period of six months. For second DUI offenses, the IID is required for a period of one year. For third DUI offenses, the IID is required for a period of two years. Fourth and subsequent DUI convictions result in an IID requirement for the lifetime of the offender. The offender may appeal the IID requirement after serving five years of the lifetime IID requirement. The IID requirement period begins on the date of the conviction.
IIDs are ordered in cases of refusing a chemical test. In these cases, the IID is required for six months for the first offense, one year for the second offense, two years for the third offense and for the lifetime of the offender for the fourth and subsequent offenses. The offender may appeal the IID requirement after serving five years of the IID requirement. In cases involving refusal of a chemical test, the IID requirement period begins on the date of the offense.
When the court orders the IID device, the offender is required to obtain a restricted driver’s license from the Wyoming DOT. To obtain the restricted license, the offender must apply for the restricted license. The offender must submit proof of insurance, pay a $50 reinstatement fee and submit proof of IID installation. The offender’s driving privileges may be suspended or revoked for a period of time that is longer than the IID requirement period.
The offender must install an ignition interlock device in any and all vehicles that the offender operates during the IID restriction period. The offender is responsible for any and all costs associated with the IIDs. Fees include installation, monthly lease payments or purchasing the device, calibration, inspection, monitoring and removal. If the offender installs IIDs on more than one vehicle, the offender must pay any and all costs associated with all installed IIDs.
