How the Program Works in Wyoming

You must apply for an ignition interlock restricted license and install a device in every vehicle you will drive (an employer's vehicle used only for business is exempt). The time counts only once the interlock license is issued. Fees: $50 reinstatement, the regular license fee and a $100 interlock administrative fee; SR-22 required. People eligible for SNAP may have half the device cost paid by the state. The court may order a 24/7 sobriety program instead of or in addition to the interlock. Not issued to CDL holders.
