For South Carolina superload moves weighing at least 180,000 pounds or measuring at least 16 feet wide, SCDOT requires insurance proof with the permit application and its March 2026 guidance sets $1 million auto liability plus $1 million general liability.

What Is Commercial Auto Insurance?

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. Read the national Commercial auto guide.

What to Watch for With Commercial Auto in South Carolina

Superload Size Triggers Application Proof
SCDOT’s March 2026 guidance requires proof with the permit application when gross vehicle weight is at least 180,000 pounds or overall width is at least 16 feet; it calls for $1 million automobile and $1 million general liability. Name the SCDOT permit office as certificate holder. ¹
Household-Goods Liability Tracks GVWR
The PSC/ORS household-goods application schedule lists $500,000 vehicle liability below 10,000 pounds GVWR and $750,000 at 10,000 pounds or more. Match the limit to each vehicle’s rating and ensure the authority file has the required certificate. ²
Household-Goods Cargo Is Also Filed
The South Carolina household-goods carrier form requires Form H cargo proof: $2,500 for loss or damage on one vehicle and $5,000 aggregate at any one time and place. Review that separately from the Form E liability certificate. ²
For-Hire Carrier Rules Depend on Service
South Carolina’s Department of Insurance directs operators of for-hire vehicles such as taxis and buses to the PSC for additional information. If your operation is not household-goods or a superload but still transports for hire, verify its exact PSC class and certificate schedule before assuming a limit. ³

Which Commercial Auto Providers Have South Carolina License Records?

These providers publish a national listing for Commercial auto; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in South Carolina. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619. New Mexico does not appear in the table and is not included here; the omission does not establish that Corgi is unlicensed there. The company-reported table has no stated as-of date and does not establish product availability. ¹¹

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁴
TechInsurance arranges commercial auto insurance for small businesses.
