Successfully getting an interlock exemption form approved by the court and DMV is the most common legal alternative way how to avoid ignition interlock devices in every state after a DUI, DWI conviction happens. If a DUI case is still being fought in court, a person still has the best chances of getting out of ignition interlock punishment altogether when a lawyer can make certain legal challenges in time. Typically, the best time to fight and avoid getting an interlock device is at the first DMV license suspension hearing within 30 days after a DUI arrest. At the DMV hearing when an expert DUI attorney can keep your license from suspension in the first place, this good outcome also immediately gets you out of an ignition interlock requirement in most cases.
