A Better Way to Manage Testing

Testing Should Protect Your Workplace — Not Slow It Down

A drug-free workplace program involves more than sending an employee to a clinic. The right test has to be ordered under the right authority, at the right location, using the right collection process and documentation. Results must move through the appropriate laboratory and MRO workflow, and time-sensitive events need immediate attention.

Drug Test Compliance customizes the testing process around your organization so drug and alcohol testing can support your safety, hiring and compliance goals without creating unnecessary administrative burden.

In addition to our own walk-in clinic capabilities, we have access to more than 35,000 specimen collection points through our nationwide network.

Compliance-Focused Administration

We help employers apply the correct DOT or non-DOT testing process, maintain organized program records and coordinate qualified service providers. Employers retain their legal and regulatory responsibilities, while DTC helps make those responsibilities easier to execute.

Professional Collection Standards

DOT urine collections are coordinated through compliant collection sites using required federal procedures. Alcohol testing workflows use qualified technicians and properly maintained/calibrated breath-testing equipment as required for the testing program.

Dedicated Customer Support

Our team assists with scheduling, testing requirements, collection-site questions, status updates, results and exceptions so employers have a real point of contact when a testing event needs attention.

Choose the Right Testing Authority

DOT-Regulated or Non-DOT?

The first decision is not which drug panel to order. It is determining why the employee is being tested and under what authority. DOT-regulated and non-DOT tests are different programs and should not be mixed.

Federal Transportation Testing

DOT-Regulated Drug & Alcohol Testing

DOT testing applies to employees performing safety-sensitive functions regulated by agencies such as FMCSA, FAA, FRA, FTA, PHMSA and the U.S. Coast Guard. Federal rules prescribe the testing procedures and limit employer flexibility.

  • Pre-employment, random and post-accident testing
  • Reasonable suspicion / reasonable cause
  • Return-to-duty and follow-up testing
  • Federal testing panel and cutoff requirements
  • DOT collection, laboratory and MRO procedures
  • Agency-specific program requirements
Employer / Company Authority

Non-DOT Workplace Drug & Alcohol Testing

Non-DOT testing gives employers more flexibility to design a program around their industry, workforce, risk profile and company policy, but state and local laws can affect when and how testing is conducted.

  • Pre-employment testing
  • Random employee testing where permitted
  • Post-accident and reasonable-suspicion testing
  • Custom drug panels and specimen options
  • Company-specific testing policies
  • State and local compliance considerations
Testing Throughout Employment

One Partner for Every Testing Reason

We coordinate workplace testing across the employment lifecycle. The exact rules depend on whether the test is DOT-regulated or company-authority/non-DOT and on applicable state and local requirements.

01

Pre-Employment

Get candidates tested quickly before placement or before they begin regulated safety-sensitive duties.

02

Random

Ongoing random selections, scheduling and program administration for DOT and permitted non-DOT programs.

03

Post-Accident

Time-sensitive testing coordination after qualifying DOT events or under an employer’s non-DOT policy.

04

Reasonable Suspicion

Responsive testing support after the required employer or supervisor determination has been made.

05

Return-to-Duty

Employer-directed DOT RTD testing after the employee completes the required SAP process and is eligible to test.

06

Follow-Up

Coordination of SAP-prescribed DOT follow-up testing and employer-directed non-DOT follow-up programs where applicable.

Testing Methods

Drug & Alcohol Testing Options for Different Workplace Needs

Test type matters. DOT programs must follow federal requirements, while non-DOT employers may have additional options depending on policy and applicable law. We help coordinate the method that fits the testing authority and purpose.

Urine Drug Testing Widely used for DOT and non-DOT workplace testing with laboratory-based testing options.
Oral Fluid Testing Directly observed collection option for eligible non-DOT programs; DOT use depends on federal operational availability.
Hair Drug Testing Non-DOT option used by some employers when a longer retrospective detection window is desired.
Breath Alcohol Testing Alcohol testing coordinated through qualified technicians and appropriate breath-testing equipment.
Simple for the Employer

From Test Order to Result

Our job is to make the testing process feel simple even when the compliance workflow behind it is not.

1 Identify the Test DOT or non-DOT, reason for test, specimen type, panel and employer requirements.
2 Schedule the Donor Choose an appropriate collection location or arrange an on-site/mobile collection.
3 Complete Collection The donor follows the required collection and documentation process.
4 Lab / MRO Review When applicable, laboratory testing and Medical Review Officer review are completed.
5 Results & Records The employer receives the appropriate result and maintains the required program documentation.
Side-by-Side Comparison

The Difference Between DOT and Non-DOT Testing

The original DTC page compared DOT and non-DOT testing across regulatory scope, applicability, testing requirements, drug panels and consequences. The comparison below keeps that information but makes the distinction easier to understand.

Program Area DOT-Regulated Testing Non-DOT / Company-Authority Testing
Regulatory Scope Governed by federal transportation rules, including 49 CFR Part 40 and the applicable FMCSA, FAA, FRA, FTA, PHMSA or Coast Guard regulation. Not a DOT federal safety-sensitive test. Employer programs are governed by company policy plus applicable federal, state and local employment/testing requirements.
Who It Applies To Employees performing covered transportation safety-sensitive functions, such as qualifying CDL drivers, aviation employees, railroad employees, transit employees, pipeline workers and maritime personnel. Employees tested under company authority, including many positions in construction, manufacturing, healthcare, offices and other non-DOT-regulated workplaces.
Testing Reasons Federal regulations prescribe testing circumstances such as pre-employment, random, post-accident, reasonable suspicion/cause, return-to-duty and follow-up. Employers generally have more flexibility, but the testing reasons must fit the company’s policy and applicable state/local laws.
Panel & Cutoffs Uses the federally required DOT drug panel, cutoff concentrations and testing procedures. Employers cannot simply add extra company-authority drugs to a DOT test. Employers may be able to choose different panels, specimen types and program rules based on business needs and applicable law.
Collection & Documentation Must follow DOT collection, laboratory, alcohol-testing, MRO and documentation requirements. Procedures can be more flexible, although consistency, defensible policies and applicable state law remain important.
Marijuana / THC DOT marijuana testing remains governed by federal DOT rules regardless of state marijuana legalization. Employer THC testing can be restricted or affected by state and local marijuana/employment laws.
Consequences DOT violations can require removal from safety-sensitive duties and the federal SAP/RTD process, in addition to agency-specific consequences. Employment consequences are generally determined by the employer’s lawful policy, applicable contracts and state/local law rather than DOT rules.

Can you manage our random drug-testing program?

Yes. DTC provides random-pool administration, selections, notifications, scheduling, completion monitoring and program records for eligible DOT and non-DOT programs.

What types of specimens can employers use?

Depending on testing authority and applicable law, options can include urine, oral fluid and hair for drug testing and breath for alcohol testing. DOT testing is restricted to federally authorized procedures and operationally available methods.

Where can I check workplace drug-testing laws for my state?

DTC maintains separate state-law resources for workplace drug testing and marijuana employment laws. These resources are informational and should be used together with current legal guidance when developing or changing an employer policy.
