DOT SAP Evaluation in South Carolina — 13 Providers Listed

South Carolina's trucking is built around the Port of Charleston and the I-26 corridor inland to Columbia and Spartanburg, with I-85 through the Greenville-Spartanburg manufacturing belt, home to BMW and Michelin, and I-95 down the coast. Inland Port Greer moves containers between the port and the Upstate. Below are 13 listings for South Carolina, 3 of which say on their own website they perform DOT SAP evaluations, with offices in Clinton, Greenville and North Charleston. The other 10 listings are for treatment or testing, which you may need later in the process, not for the evaluation itself.

The SAP process itself is federal — 49 CFR Part 40, Subpart O — so nothing about it changes at the South Carolina line. Where South Carolina does come in is the CDL: the South Carolina Department of Motor Vehicles removes the commercial privilege from a driver the Clearinghouse reports as prohibited — a 60-day requirement on every state since November 18, 2024 (FMCSA) — and puts it back when your status clears.

Yes, you can do the evaluation by video from South Carolina: 49 CFR §40.291 leaves that to the SAP's discretion, and a legitimate telehealth SAP will tell you in one sentence whether their license covers South Carolina. A SAP across the line in North Carolina and Georgia is also an option, in person or by video, under the same licensing question. What cannot be done by video is the return-to-duty test itself, which is an observed collection at a collection site.
