When Is a DUI a Felony in Wyoming & South Dakota?
Most first-time impaired driving offenses are misdemeanors, but certain situations escalate them to felony charges in South Dakota and Wyoming. At Just Criminal Law, we believe it’s important to understand the key differences in state laws regarding these serious charges.
In Wyoming, a DWUI becomes a felony if it’s the fourth or subsequent offense within ten years. Causing serious injury or committing vehicular homicide while impaired also qualifies as a felony.
In South Dakota, a DUI becomes a felony if you’re convicted three times within ten years. Like Wyoming, driving under the influence and causing serious injury, death, or harm to someone leads to felony charges.
Penalties for DUI in Wyoming & South Dakota
Wyoming imposes significant penalties for felony DWUI, with consequences depending on factors like prior offenses or whether serious injury occurred. Penalties may include several years in state prison, fines up to $10,000, long-term or even permanent driver’s license revocation, and mandatory use of an ignition interlock device (IID) for an extended period if driving privileges are reinstated. In addition to the immediate penalties, a felony conviction carries long-term repercussions, impacting civil rights and limiting future opportunities.
Similarly, South Dakota enforces strict penalties for felony DUI, classified by felony level (e.g., Class 6, 5, or 4). Possible consequences include lengthy prison sentences with maximum terms based on the felony category, substantial fines, extended or permanent license revocation, and IID requirements. As with Wyoming, a felony conviction in South Dakota has far-reaching effects on various aspects of life. These penalties underscore the seriousness with which both states address felony impaired driving.
Potential Defenses for Felony DUI Charges in Wyoming & South Dakota
One common defense challenges the legitimacy of the traffic stop itself. If law enforcement lacked reasonable suspicion to initiate the stop, any evidence gathered during the encounter could be dismissed.
Another approach involves disputing the reliability of chemical tests like breathalyzers or blood tests. These tests can produce inaccurate results due to issues like improper calibration, flawed testing procedures, or external factors such as medical conditions or medications. Highlighting testing errors can significantly weaken the prosecution’s argument.
The handling of evidence is also a critical factor. Breaks in the chain of custody or mishandling of evidence can undermine its credibility. Scrutinizing police procedures and protocol adherence can sometimes reveal mistakes that impact the case.
Finally, presenting mitigating factors, such as constitutional violations during the arrest or medical conditions influencing behavioral conditions, can provide additional defense angles.
