THE SHORT ANSWER
Prior DUI convictions can increase penalties for a new DUI offense in South Carolina. The sentence depends on the number and timing of previous convictions and other factors, including blood alcohol concentration.
Key takeaways
- Qualifying prior DUI offenses within a 10-year period may increase sentencing penalties.
- Repeat offenses can bring additional jail time, fines, license consequences, and ignition interlock requirements.
- Reviewing past conviction records and dates is essential when assessing enhanced penalties.
If you are facing a DUI charge, one of your first questions is probably: How serious is this going to be?
In South Carolina, the answer often depends on one key factor — whether you have prior DUI convictions.
Under South Carolina DUI laws, repeat offenses dramatically increase the penalties you face, including longer jail sentences, higher fines, and extended license suspensions.
At Coastal Law, our DUI and Criminal Defense team regularly helps clients understand how prior convictions affect their case and what options may protect their future.
This guide explains how prior DUI convictions in SC affect sentencing and what you should know if you are charged again.
Understanding DUI Sentencing in South Carolina
South Carolina DUI penalties are governed by S.C. Code Ann. § 56-5-2930, which outlines how the state punishes impaired-driving offenses. The law establishes a tiered system.
That means penalties increase based on:
- Your blood alcohol concentration (BAC)
- The number of prior DUI convictions
- Whether the offense caused great bodily injury or death
For sentencing purposes, South Carolina uses a 10-year lookback period. If you have prior DUI convictions within the last 10 years, they will significantly increase your sentence.
First-Offense DUI in South Carolina
If this is your first DUI conviction, penalties depend largely on your BAC level.
Generally, a first offense may include:
- 48 hours to 90 days in jail
- Fines ranging from approximately $400 to over $1,000
- Six-month license suspension
- Alcohol and Drug Safety Action Program (ADSAP) participation
Even for a first offense, the consequences are serious. But they become much more severe with repeat DUI offenses in SC.
Second DUI Offense in South Carolina
If you are convicted of a second DUI offense within 10 years, penalties increase significantly.
Under S.C. Code § 56-5-2930, a second offense may result in:
- 5 days to 1 year in jail (depending on BAC)
- Substantially higher fines
- One-year license suspension
- Installation of an ignition interlock device
The court will consider prior DUI convictions in SC when determining mandatory minimum jail time. Unlike some other charges, DUI sentencing has strict minimum requirements that judges must follow.
Third DUI Offense: A Major Escalation
A third DUI offense within 10 years brings even steeper penalties:
- 60 days to 3 years in prison
- Fines up to several thousand dollars
- Two-year license suspension
- Mandatory ignition interlock
At this point, the court sees the offense as a pattern of behavior. Prosecutors often pursue the maximum penalties in repeat DUI offense SC cases.
If you are facing a third DUI, it is critical to speak with a Myrtle Beach DUI lawyer immediately.

Fourth or Subsequent DUI: Felony DUI in South Carolina
A fourth DUI conviction within 10 years is classified as a felony in South Carolina.
Penalties may include:
- 1 to 5 years in prison
- Permanent criminal record as a felon
- Long-term license revocation
Additionally, under S.C. Code Ann. § 56-5-2945, a DUI that results in great bodily injury or death carries even more severe felony consequences. You can review that statute here:
Felony DUI charges can permanently affect employment, firearm rights, and other civil liberties.
How the 10-Year Lookback Period Works
South Carolina calculates prior DUI convictions based on the offense date, not the conviction date.
This means if you were charged with DUI nine years and eleven months ago, and you are charged again today, the prior offense will likely count against you.
Because timing matters so much, carefully reviewing your prior record is essential in any DUI sentencing case in South Carolina.
Can Prior DUI Convictions Be Challenged?
In some cases, you may be able to challenge prior DUI convictions.
For example:
- Was the prior conviction constitutionally valid?
- Were your rights properly explained?
- Is the prior offense actually within the 10-year lookback period?
A detailed case review can sometimes uncover defenses that affect how prior DUI convictions SC are counted.
At Coastal Law, our team evaluates every aspect of the prosecution’s case—including how prior convictions are used to increase penalties.
Additional Consequences of Repeat DUI Offenses in SC
Beyond jail time and fines, repeat DUI convictions can lead to:
- Increased auto insurance rates
- Mandatory ignition interlock device costs
- Employment consequences
- Professional licensing issues
- Travel restrictions
For many people, these collateral consequences can be just as damaging as the court-imposed penalties.
Why Legal Representation Matters in Repeat DUI Cases
When you are facing enhanced penalties, the stakes are high. Prosecutors often push aggressively in repeat DUI offense SC cases, especially when prior convictions exist.
An experienced criminal defense attorney can:
- Analyze prior convictions
- Examine BAC testing procedures
- Challenge traffic stops
- Negotiate potential plea options
- Prepare your case for trial if necessary
