Nationwide coordination for DOT follow-up testing required under a Substance Abuse Professional (SAP) testing plan after a DOT drug or alcohol violation and successful completion of the return-to-duty process.
The SAP determines the number, frequency, and type of follow-up tests. The employer controls the actual unannounced testing dates and is responsible for ensuring that the plan is completed.
Purchase sends you directly to checkout. DOT follow-up drug testing requires a directly observed collection.
Follow-up testing is the next stage of the DOT return-to-duty process. It does not replace the return-to-duty test.
After a DOT drug or alcohol violation, the driver must complete the Substance Abuse Professional process, including required education and/or treatment and the SAP's follow-up evaluation.
The return-to-duty test cannot occur until the SAP has determined that the driver successfully complied with the prescribed education and/or treatment requirements.
Before the driver may resume DOT safety-sensitive functions, the applicable return-to-duty test must be successfully completed.
A drug return-to-duty test must have a verified negative result. An alcohol return-to-duty test must have a result below 0.02.
The SAP's written follow-up evaluation report includes the follow-up testing plan and is provided directly to the employer's Designated Employer Representative (DER).
If the employer has not received the follow-up testing plan, the employer should contact the SAP and make sure the required plan is obtained through the proper DOT process.
Once the return-to-duty requirements have been satisfied and the driver returns to safety-sensitive duties, the employer must begin carrying out the SAP's follow-up testing plan.
DOT follow-up testing is mandatory testing prescribed by the Substance Abuse Professional after the driver successfully progresses through the return-to-duty process.
Follow-up testing is not ordinary pre-employment or random testing. It exists because the employee previously committed a DOT drug or alcohol testing violation.
The SAP determines the number and frequency of required follow-up tests and whether testing is for drugs, alcohol, or both.
The employer is responsible for implementing the plan, selecting the actual unannounced testing dates, and ensuring all required tests are completed.
A standard DOT drug test normally uses the regular DOT specimen collection process. A DOT follow-up drug test is different because federal DOT rules require the follow-up drug collection to be conducted under direct observation.
Under 49 CFR §40.67, direct observation is required when the reason for the drug test is return-to-duty or follow-up.
The collection site therefore must perform the additional DOT observed-collection procedures rather than processing the appointment as a standard drug collection.
Because of this additional observed collection requirement, CDL Inquiry's follow-up drug testing service is $95, compared with $65 for a standard DOT drug test.
The $95 amount is CDL Inquiry's service price. It is not a government-established DOT or FMCSA fee.
Federal regulations establish a minimum requirement, but the SAP may prescribe a more extensive testing plan based on the individual case.
At least six unannounced follow-up tests must be completed during the first 12 months of safety-sensitive duty.
The federal minimum of six tests applies during the first 12 months following return to safety-sensitive duty.
The SAP may require additional follow-up testing during the following 48 months of safety-sensitive duty.
CDL Inquiry can coordinate individual testing appointments, but the employer remains responsible for managing the SAP-directed schedule and deciding when each required test will occur.
The employer should maintain the SAP follow-up testing plan and track how many required tests remain, the applicable testing period, and which types of testing are required.
The SAP establishes the number and frequency of tests, while the employer determines when each individual follow-up test will occur.
Follow-up testing must be scheduled without a discernible pattern and without giving the driver advance notice of the testing schedule.
A DOT random test cannot be substituted for a required SAP-directed follow-up test.
Once the employer has the SAP follow-up testing plan, the company should maintain that plan and contact CDL Inquiry each time it decides to send the driver for one of the required follow-up tests.
Confirm which test is required and track the employer's remaining follow-up testing obligations.
The employer decides when to test while keeping the schedule unpredictable and avoiding advance notice.
When ready to send the driver, contact CDL Inquiry so we can coordinate the collection site and prepare the appropriate authorization form.
When the employer is ready to conduct one of the SAP-directed follow-up tests, CDL Inquiry can coordinate the testing process and prepare the authorization required for the collection site.
The employer determines which SAP-directed follow-up test needs to be completed.
Contact CDL Inquiry when the company is ready to send the driver for the required follow-up test.
CDL Inquiry prepares the appropriate testing authorization and coordinates the collection-site instructions.
The driver is sent to the authorized testing location and completes the required DOT follow-up testing procedure.
If the employer has reviewed the SAP plan and is ready to send the driver for testing, place the order and CDL Inquiry can prepare the testing authorization and collection-site instructions.
Schedule Follow-Up TestingBoth are part of the DOT return-to-duty process, but they occur at different stages and serve different purposes.
| Testing Type | Purpose | When It Occurs | Drug Test Observation |
|---|---|---|---|
| Return-to-Duty Test | Required before the employer may allow the employee to resume DOT safety-sensitive functions. | After successful SAP compliance and before return to safety-sensitive duty. | Direct observation is required for DOT return-to-duty drug collections. |
| Follow-Up Test | Continues monitoring after the employee returns to safety-sensitive duties. | According to the SAP-directed follow-up testing plan. | Direct observation is required for DOT follow-up drug collections. |
The employer remains responsible for carrying out the SAP's follow-up testing directions even when CDL Inquiry or another service agent assists with testing coordination.
The employer must ensure that all required follow-up testing is performed according to the SAP's plan.
Actual testing dates must remain unannounced and should not follow a predictable pattern.
Tests conducted under the employer's random testing program cannot substitute for required follow-up tests.
A cancelled follow-up test cannot be counted as one of the completed tests required by the SAP plan.
Follow-up testing requirements can continue through a change of employer or a break in service when applicable.
The employer should maintain accurate records of completed follow-up tests and continue managing the plan until all requirements have been completed.
Follow-up testing occurs after the employee successfully completes the applicable SAP and return-to-duty requirements and returns to safety-sensitive duty. A return-to-duty drug test must have a verified negative result, and an applicable alcohol return-to-duty test must have a result below 0.02.
The SAP's written follow-up evaluation report includes the follow-up testing plan and is provided to the employer's Designated Employer Representative. If the employer has not received the plan, the employer should work with the SAP to obtain the required information.
The employer does. The SAP determines the number, frequency, and type of follow-up testing, while the employer chooses the actual dates. Testing must remain unannounced and unpredictable.
Review the SAP plan, choose the employer's appropriate unannounced testing date, and contact CDL Inquiry when ready to send the driver. CDL Inquiry can coordinate the testing location and prepare the authorization form.
Yes. DOT rules require follow-up drug collections to be conducted under direct observation.
DOT follow-up drug testing requires a directly observed collection rather than the standard collection process. Because of that additional collection requirement, CDL Inquiry's follow-up drug testing service is $95, compared with $65 for a standard DOT drug test.
The SAP determines the number and frequency of follow-up tests and whether testing is for drugs, alcohol, or both. DOT rules require a minimum of six unannounced tests during the first 12 months of safety-sensitive duty following return.
Yes. The SAP may require follow-up testing during an additional 48 months of safety-sensitive duty after the first 12-month period.
No. DOT random tests cannot be substituted for required follow-up tests.
No. The employer controls the testing dates, and follow-up testing must remain unannounced.
The SAP may prescribe drug testing, alcohol testing, or both. The employer must implement the plan as written. Contact CDL Inquiry when ready to schedule the required testing so the correct authorization and testing arrangements can be prepared.
Employers should use the applicable DOT regulations, FMCSA regulations, and the driver's SAP report as the controlling sources for actual follow-up testing requirements.
Review the SAP follow-up testing plan, select the employer's unannounced testing date, and place the order when you are ready to send the driver. CDL Inquiry can coordinate the testing location and prepare the appropriate authorization form.
