Charleston County DUI Guide

Charleston Police logged 592 DUI arrests in 2024, up 31% from the year before — even as fatal crashes countywide dropped 40.5%. Officials point to that gap as proof the heavier enforcement is working, which means anyone driving through downtown on a weekend night is walking into one of the most aggressive checkpoint environments in the state.

Where and When Enforcement Concentrates

Five agencies share jurisdiction here: Charleston Police downtown, North Charleston Police, Mount Pleasant Police, the Charleston County Sheriff's Office in unincorporated areas, and South Carolina Highway Patrol on the interstates. Checkpoints cluster on the peninsula at spots like King and Huger, Calhoun and Halsey, and East Bay and South Street, and out in the suburbs at Folly Road near Albemarle, Harborview Road, and Highway 61 in West Ashley. Highway Patrol leans on the I-26 and I-526 ramps and the approaches to the Ravenel Bridge. Thursday through Saturday nights, 9 p.m. into the early morning hours, is when patrols run heaviest, intensifying further around Memorial Day (in coordination with Joint Base Charleston's own security forces) and the Christmas/New Year's corridor.

South Carolina's video-recording requirements shape a lot of what happens after the stop. Officers have to keep a suspect on camera continuously from the initial stop through the Miranda advisement — if the footage loses sight of a suspect's feet during the walk-and-turn test, or the audio cuts out during rights advisement, defense attorneys in this county routinely get evidence suppressed or charges dismissed outright. Combined with South Carolina's DUI PTI ban (more on that below) and the officer-as-prosecutor system common across the state, a meaningful share of Charleston County DUIs get negotiated down to reckless driving or DUAC rather than going to trial as charged.

Getting Your Car Back

Which impound lot holds your car depends on who towed it. Inside Charleston city limits, Jennings Towing is the official franchise operator, based at 2026 Meeting Street Extension — expect a $150 to $200 tow fee and $20 to $30 a day in storage after the first 24 hours, with both cash and cards accepted by ordinance. Outside the city, in unincorporated areas or on the interstate, County Sheriff's deputies and Highway Patrol dispatch through a rotating wrecker list instead, capped by the state at a $272 flat tow fee and $47 a day storage. If you don't know which lot has your car, the county's online Tow Car Locator portal lets you search by plate or VIN rather than fighting through a busy non-emergency phone line (it doesn't cover the town of Folly Beach specifically).

The bigger complication is the license itself. Refuse the breath test, or blow 0.15% or higher, and your license is confiscated and suspended on the spot — and every impound lot in the county is required to verify a valid license before releasing a vehicle. That means a suspended driver can't retrieve their own car alone; you need one licensed person to drive you there and a second licensed person to actually sign for and drive the vehicle off the lot. There's also a mandatory investigative hold before any release is possible at all: 12 hours for a first offense, 24 for a second, 48 for a third or beyond. If you think the tow itself was improper or the fees exceeded the legal cap, a tow hearing can be filed at Charleston County Magistrates Court (Civil Division), 4045 Bridge View Drive, for an $80 filing fee.

Booking and Bond

Everyone in the county lands at the Sheriff Al Cannon Detention Center, 3841 Leeds Avenue in North Charleston. Booking itself typically runs 3 to 6 hours, partly because the evidentiary breath test has to happen in a dedicated, video-recorded room with a mandatory 20-minute observation period beforehand. The facility is entirely cashless — no currency changes hands with staff at all. Bond money moves through digital kiosks (JailATM or Securus) or through a bail bondsman, and bond hearings themselves aren't continuous; the Central Bond Hearing Court convenes exactly three times on weekdays (10 a.m., 2 p.m., and 7 p.m.) and twice on weekends, dropping the evening slot. Book in right after the 10:15 docket closes, and you're waiting until 2 p.m.

One thing sets Charleston County apart from most of the state: it's the only county that generates a formal Pretrial Services Report for every defendant and guarantees a public defender is physically present at that very first bond hearing for anyone indigent or carrying less than $500 in cash. Defendants who score as low flight-risk are overwhelmingly granted Personal Recognizance release with no money down — a structural advantage that reduces how often first-time DUI defendants here actually need a commercial bondsman at all.

Court and the PTI Trap

Where your case is heard depends on who arrested you. Sheriff's Office and Highway Patrol arrests go through the County Magistrates/Summary Courts at 4045 Bridge View Drive; Charleston Police arrests go to the City of Charleston Municipal Court at 180 B Lockwood Boulevard instead. One detail that surprises a lot of defendants: South Carolina explicitly bans the use of Pre-Trial Intervention for DUI and DUAC charges, even though PTI is available for many other first-time, non-violent offenses in the same courts. A separate Adult Drug Court exists for defendants with a documented substance dependency, but it requires an upfront guilty plea held in abeyance through a minimum 15-month, five-phase program.

Given the PTI ban and the officer-as-prosecutor structure, one real strategic lever remains: demanding a jury trial at the Magistrate Court level. It's a right, not a formality, and forcing a six-person jury trial creates enough logistical pressure on an already-stretched prosecution that favorable plea offers often follow.

Security varies sharply by building. Magistrate and Summary Courts enforce a total ban on phones and other electronics — no lockers, no exceptions — while dress code bans hats, tank tops, shorts, and flip-flops. Parking near the historic Judicial Center at 100 Broad Street is genuinely difficult; plan on a paid garage at 85 Queen Street or 82 Cumberland Street ($20 flat) and a several-block walk, since street meters cap out at two hours.

The License Suspension Deadline

Separately from the criminal case, refusing the breath test or testing at 0.15% BAC or above triggers an automatic Implied Consent suspension the moment it happens. You have exactly 30 calendar days from the Notice of Suspension to file a hearing request with the South Carolina Office of Motor Vehicle Hearings, along with a non-refundable $200 fee. Miss it, and the suspension stands with no further appeal. A defense attorney can file electronically and often gets a Temporary Alcohol License issued within 48 hours; a self-represented defendant mailing the paper form to the Columbia headquarters should expect a considerably longer wait.

As of May 19, 2024, South Carolina's "Emma's Law" expansion changed the ignition interlock landscape substantially. Every DUI conviction now requires an interlock device regardless of BAC level — the old route-restricted license option, which used to let low-BAC first offenders drive to work without one, is gone.

Interlock Installers and Monitoring

Several certified installers serve the area: LifeSafer offers same-day scheduling through an online booking tool; Intoxalock has a location on Sam Rittenberg Boulevard with flexible bi-monthly payment plans; Smart Start operates out of Savannah Highway with bilingual English/Spanish device options. If a court orders continuous alcohol monitoring instead of, or alongside, an interlock, a regional monitoring provider covers SCRAM and GPS tracking equipment for the area. After a conviction or an Implied Consent suspension, you'll also need to file an SR-22 — a certificate of financial responsibility your insurer submits directly to the DMV, not a separate policy — through your existing insurer or a local agent who handles high-risk placements.

Mandatory Treatment: ADSAP

Any DUI or DUAC conviction, or a license suspended under Implied Consent, requires completing South Carolina's Alcohol and Drug Safety Action Program — out-of-state DUI schools don't count without prior coordination through the Interstate ADSAP Office. In Charleston County, intake runs through the county's designated agency at 3685 Rivers Avenue in North Charleston, with walk-in assessments Monday through Friday, 8:30 a.m. to 3 p.m. Bring a $500 initial deposit, a valid photo ID, and a 10-year driving record stamped within the last 30 days. Total program cost is capped at $2,500 depending on your clinical assessment, and completion can take up to 12 months depending on what that assessment finds.
