Understanding DOT Testing Requirements in South Carolina

As an employer operating in South Carolina, it can be challenging to keep up with both federal DOT rules and any state-level expectations that affect your drivers. While the DOT regulations are consistent nationwide, you still have to consider how they apply to your routes, contracts, and operations in and around North Charleston. We help you understand when federal rules apply, how they intersect with your internal policies, and what documentation you should keep on file at your place of business.

Our team can walk you through common testing situations for companies that run along I-26, serve the Port of Charleston, or move freight between nearby cities like Summerville and Goose Creek. We explain the differences between pre-employment, random, post-accident, and reasonable suspicion testing so you know exactly when each type is required. By clarifying these details before an issue arises, you can reduce confusion, train supervisors confidently, and maintain a consistent approach across your entire CDL workforce.

Key areas we can help you evaluate include:

• Driver roles and coverage – Determining which employees fall under DOT regulations based on the vehicles they operate and the work they perform.
• Policy alignment and updates – Reviewing your current handbook or policies to see if they clearly reflect current DOT rules and company expectations.
• Recordkeeping practices – Organizing test results, chain-of-custody forms, and program records so they are easy to access if you face an audit or compliance review.
• Supervisor training needs – Identifying who should receive reasonable suspicion training and how often refresher training might be helpful.

By taking time to review these elements with a knowledgeable testing partner, you can feel more prepared for audits, customer reviews, or contract requirements. This proactive approach helps ensure that your DOT testing program supports safety on the road while also protecting your company’s reputation and operations.
