Understanding DUI vs. DUAC in South Carolina
Getting charged with drunk driving in South Carolina can be confusing, especially when you hear terms like DUI and DUAC. While they sound similar, these two charges carry different legal standards and consequences.
Knowing the difference can help you take the right steps to protect your rights and minimize the impact on your life.
What DUI means under South Carolina law
In South Carolina, a DUI (Driving Under the Influence) occurs when alcohol or drugs materially impair your ability to drive.
Under S.C. Code § 56-5-2930, you can be charged even with a BAC below .08 if alcohol or drugs impair your driving. Prosecutors may also pursue charges whenever your driving appears unsafe due to alcohol or drug use.
For example, you might have only one or two drinks at dinner and feel fine to drive. But if an officer observes you swerving, reacting slowly or failing to follow traffic signals, they can still arrest you for DUI — even if your BAC is under the legal limit.
How DUAC is different
Unlike a DUI, Driving with an Unlawful Alcohol Concentration (DUAC) does not depend on proving that you were impaired. Instead, it is based purely on your BAC.
So, if your test results show a BAC of .08 or higher, authorities can charge you with DUAC — even if your driving appeared normal. In other words, DUAC focuses on numbers, not behavior.
Penalties for DUI and DUAC
The penalties for both charges are similar and can include:
- Fines
- Jail time
- License suspension
- Mandatory alcohol education programs
- Long-term consequences such as higher insurance rates or a criminal record affecting employment opportunities
The severity of these penalties often depends on factors like prior offenses, the BAC level and the circumstances of the stop.
Understanding these consequences can help you see why distinguishing between a DUI and a DUAC matters, especially when it comes to fighting impaired driving charges or minimizing future impacts.
Which charge is worse?
It is important to understand that you should not take any of these charges lightly. A DUI might seem more subjective since it is based on observed impairment, but both carry serious consequences that can follow you for years.
The difference often comes down to evidence — whether the state focuses on your actions behind the wheel or the chemical test results.
Protecting your rights in South Carolina
Facing a DUI or DUAC charge in South Carolina can seriously affect your driving record, your freedom and your future. These laws are complex, and the differences between the two charges can greatly influence the outcome of your case.
Working with an experienced defense attorney can help you understand your options, build a strong defense and protect your rights as you navigate the legal process.
