Dr. Alan Tebby and Dr. Lemuel Byrd have coordinated fleet DOT drug testing for Charlotte carriers since 1991. With 84+ years of combined medical experience and FMCSA certification, we understand the compliance challenges facing fleet safety managers. Our 4.8-star rating reflects our commitment to providing reliable, compliant testing services that keep your drivers on the road and your fleet in compliance.
Fleet drug testing coordination requires managing multiple testing types, strict timelines, Clearinghouse requirements, and comprehensive record keeping. Whether you’re a safety manager for a 5-truck operation or a 500-driver fleet, understanding service options helps you maintain DOT compliance efficiently.
✓ Why Charlotte Fleets Trust Our Testing Coordination
We’ve coordinated testing for Charlotte fleets ranging from 2 drivers to 200+ drivers. Our experience means we understand the practical challenges: drivers who need testing while on routes, urgent post-accident coordination, Clearinghouse reporting deadlines, and record retention requirements. We handle the compliance burden so safety managers can focus on operations.
Fleet size determines whether you can manage testing in-house or need consortium services. Understanding your obligations helps you choose the right approach.
| Fleet Size | Testing Management | Annual Testing Volume | Recommended Solution |
|---|---|---|---|
| 1-5 Drivers | Consortium required | 3-8 tests/year | Join consortium/C/TPA |
| 6-20 Drivers | Consortium or in-house | 15-40 tests/year | Consortium recommended |
| 21-50 Drivers | In-house possible | 50-120 tests/year | C/TPA or in-house with coordinator |
| 51+ Drivers | In-house typical | 120+ tests/year | In-house with dedicated staff or robust C/TPA |
Random testing is the most complex aspect of fleet compliance. Federal regulations under 49 CFR 382.305 establish strict requirements that fleets must meet.
| Number of Drivers | Minimum Drug Tests | Minimum Alcohol Tests | Total Annual Tests |
|---|---|---|---|
| 5 | 3 (50%) | 1 (10%) | 4 minimum |
| 10 | 5 | 1 | 6 minimum |
| 20 | 10 | 2 | 12 minimum |
| 50 | 25 | 5 | 30 minimum |
| 100 | 50 | 10 | 60 minimum |
When drivers are randomly selected, they need immediate access to testing. Charlotte-area fleet options include:
Every new driver must complete pre-employment drug testing before performing any safety-sensitive functions. Federal regulations create specific timing requirements.
Clearinghouse Query First
Must complete Clearinghouse query before ordering drug test. Driver must have no prohibitions. Obtain electronic consent before querying.
Schedule Drug Test Immediately
After cleared Clearinghouse query, schedule drug test. Driver cannot perform safety-sensitive work until negative result received.
Results Typically Within 24-48 Hours
Negative results usually reported same day or next business day. Non-negative results go to MRO for review, adding 24-72 hours.
Driver Can Start After Verified Negative
Once verified negative result received, driver is cleared to begin safety-sensitive work. Keep test result documentation for compliance files.
Charlotte DOT Exam Center offers:
Post-accident testing has the tightest timelines in DOT regulations. Failing to test within mandated windows creates compliance violations under 49 CFR 382.303.

Fleet managers must handle multiple Clearinghouse responsibilities. Understanding requirements prevents violations.
| Clearinghouse Action | When Required | Timeline |
|---|---|---|
| Pre-Employment Query | Before every new hire | Before drug test ordered |
| Annual Query | All current drivers yearly | Once per 12 months |
| Positive Result Reporting | After verified positive test | Within 2 business days |
| Refusal Reporting | After driver refuses test | Within 2 business days |
| Negative RTD Reporting | After successful return-to-duty test | Within 2 business days |
Fleet compliance depends on maintaining proper documentation. Federal regulations specify exact retention periods.
| Record Type | Retention Period | What to Keep |
|---|---|---|
| Positive Tests | 5 years | Test result, MRO report, SAP reports |
| Negative Tests | 1 year | Test result documentation |
| Refused Tests | 5 years | Refusal documentation, circumstances |
| Random Selection Records | 2 years | Selection process, dates, drivers selected |
| Clearinghouse Queries | 3 years | Query results, driver consent forms |
| Policy Distribution | While driver employed + 2 years | Signed acknowledgment forms |
Charlotte-area fleets can access volume discounts for regular testing contracts.

Custom pricing for 100+ driver fleets
Minimum 50% of your driver pool for drug testing and 10% for alcohol testing annually. For a 10-driver fleet, you need at least 5 drug tests and 1 alcohol test per year. Some drivers may be selected multiple times while others aren’t selected at all—that’s how random selection works. FMCSA can adjust these rates based on national violation trends.
No. You must complete the Clearinghouse query first and receive results showing no prohibitions before ordering a pre-employment drug test. If the query shows a violation, you cannot hire that driver. The query must come before any drug testing or safety-sensitive work.
Document why testing couldn’t occur (driver hospitalized, no available testing facility within reasonable distance, driver couldn’t be located). Keep detailed documentation of all attempts to test and reasons for inability to meet deadlines. This documentation protects you during DOT audits, though it doesn’t eliminate the testing requirement—you tried in good faith.
Depends on fleet size. 1-5 drivers must use consortium (can’t randomly select from pool of one). 6-20 drivers can technically do in-house but consortium is usually easier and more reliable. 21+ drivers can justify in-house programs with dedicated compliance staff, though many still use C/TPA services for simplicity and risk reduction.
Positive tests and refusals: 5 years. Negative tests: 1 year. Random selection records: 2 years. Clearinghouse queries: 3 years. Policy distribution acknowledgments: while driver employed plus 2 years. Store securely with limited access to protect confidentiality. Electronic storage allowed if properly backed up.
Yes. Mobile collection services are available for Charlotte-area terminals. Typical costs: $100-250 per visit depending on number of drivers tested and location. Mobile testing works well for random testing when multiple drivers selected simultaneously, post-accident urgent needs, or terminals without nearby collection sites.
Consortium specifically provides random selection pool (required for small fleets). C/TPA (Consortium/Third-Party Administrator) provides full testing program management including random selection, Clearinghouse reporting, MRO services, record retention, and compliance support. Most providers offer both services bundled together.
Managing DOT drug testing compliance for Charlotte fleets requires coordinating multiple testing types, meeting strict timelines, maintaining accurate records, and staying current with Clearinghouse requirements. Whether you handle testing in-house or use consortium services, having reliable testing coordination protects your operation.
