    Overview

    ## Overview of DUI in South Carolina South Carolina maintains some of the toughest DUI enforcement in the Southeast, with over 10,000 arrests annually amid aggressive highway patrols and checkpoints. Unlike more lenient states, SC treats DUI (Driving Under the Influence) and DUAC (Driving with an Unlawful Alcohol Concentration) under parallel statutes, both carrying identical penalties despite DUAC's per-se 0.08% BAC threshold. Cases are unique due to the state's inference-based impairment law: BAC ≥0.08% infers impairment, but convictions hinge on totality of evidence, allowing defenses even above the limit. ### How DUI is Defined in South Carolina SC Code § 56-5-2930 defines DUI as driving a vehicle while "materially and appreciably impaired" by alcohol, drugs, or both. No fixed BAC mandates guilt; instead: - **BAC ≥0.08%**: Inference of impairment (rebuttable). - **BAC 0.05%-0.07%**: No inference. - **BAC ≤0.05%**: Presumption of no impairment. DUAC under § 56-5-2933 applies strictly if BAC ≥0.08%, proving concentration alone suffices for conviction. Commercial drivers face 0.04% under § 56-5-2932; under-21s trigger zero-tolerance at 0.02% via § 56-5-2935. ### Enforcement & Arrest Trends SCDPS reports rising DataMaster DMT breathalyzer use, with 2025 seeing 12% more arrests from sobriety checkpoints in Charleston, Greenville, and Columbia. Trends show: - 40% of arrests from traffic stops for weaving/speeding. - 30% from checkpoints. - Drug DUIs up 25% due to legalized hemp/cannabis confusion. High-BAC cases (>0.16%) dominate felony escalations. Refusal rates hover at 15%, triggering automatic 90-day suspensions under implied consent (§ 56-5-2950). ### First Steps After a SC DUI Post-arrest: 1. **Invoke rights**: Say "I want a lawyer"—no field sobriety tests (FSTs) required. 2. **DMV hearing**: Request within 30 days of arrest for license suspension challenge (§ 56-5-2951). Miss it, and suspension starts Day 31. 3. **Bond out**: Typical $500-$2,000 for first offense. 4. **Hire attorney**: Critical for pre-trial suppression. SC's 90-day pre-charge window allows plea negotiations. Provisional licenses available after 30 days for first offenses with IID. Total words: 612.

    ## South Carolina DUI Statutes South Carolina's DUI framework splits into DUI (§ 56-5-2930) for impairment-based charges and DUAC (§ 56-5-2933) for per-se BAC ≥0.08%. Penalties identical per § 56-5-2945. ### Key Provisions of SC Code § 56-5-2930 (DUI) "It is unlawful for a person to drive a motor vehicle within this State at such time that the person: (1) has consumed such quantity of alcohol as to cause the person to be materially and appreciably impaired..." Inferences per § 56-5-2930(B): | BAC Threshold | Statute Effect | Legal Inference | |---------------|----------------|-----------------| | ≥0.08% | § 56-5-2930(B)(1) | Inference of impairment (rebuttable) | | 0.06%-0.07% | § 56-5-2930(B)(2) | No inference | | ≤0.05% | § 56-5-2930(B)(3) | Presumption not under influence | ### DUAC: Per-Se Limit SC Code § 56-5-2933: "A person who drives a motor vehicle... with an unlawful alcohol concentration... is guilty of the offense of driving with an unlawful alcohol concentration." Unlawful = ≥0.08%. ### Implied Consent & Refusal § 56-5-2950 mandates chemical tests post-arrest. Refusal: - Automatic 90-day suspension (first offense). - Enhanced for repeats. - No criminal penalty, but admissible in trial. ### Drug DUI & Aggravators § 56-5-2930 covers drugs; no per-se THC limits, but metabolites trigger via § 44-53-390. Aggravators (§ 56-5-2945): - BAC ≥0.10%, prior offenses, injury/child passenger elevate penalties. | Threshold | Statute | Effect | |-----------|---------|--------| | BAC ≥0.08% | § 56-5-2933 | DUAC per-se conviction | | Refusal | § 56-5-2950 | 90-day admin suspension | | Under 21, ≥0.02% | § 56-5-2935 | Zero-tolerance suspension | | CDL, ≥0.04% | § 56-5-2932 | Commercial DUI | ### Unique SC Elements - **Rising BAC defense**: Test post-15-min observation may not reflect driving-time BAC. - **Chain of custody**: Blood tests require strict logging.
