Short answer (updated October 14, 2026): The biggest 2026 change to DOT drug testing is a final rule published May 11, 2026 and effective June 10, 2026: when a directly observed collection would have to be an oral fluid test, it is done as a directly observed urine collection instead, because oral fluid testing is not available yet. FMCSA’s 2026 random testing rates stayed at 50% for drugs and 10% for alcohol. Fentanyl is proposed for the DOT panel but, as of today, not final.
Below is each change, what it means for a motor carrier, and the source we read it from.
Can carriers use oral fluid (saliva) drug testing in 2026?
No, not yet. DOT authorized oral fluid testing in 2023, but an employer cannot use it until HHS has certified at least two oral fluid laboratories, and there are none.
DOT’s May 2026 final rule spells out the history. DOT amended 49 CFR Part 40 on May 2, 2023, and that rule “authorized oral fluid drug testing as an additional methodology for employers to use” (91 FR 25507). The same rule explains the catch: “for an employer to implement oral fluid testing, there must be at least two HHS-certified laboratories for oral fluid testing.” One lab tests the primary specimen and a different lab handles the split specimen if the driver asks for it.
As of today:
- DOT’s own oral fluid lab page says: “Currently there are no HHS certified oral fluid drug testing laboratories” (DOT ODAPC, page last updated December 5, 2024).
- The most recent HHS list of certified labs, published September 30, 2026, says: “At this time, there are no laboratories certified to conduct drug and specimen validity tests on oral fluid specimens” (91 FR 61854).
So every DOT drug test in 2026 is still a urine test, analyzed at an HHS-certified (SAMHSA-certified) lab. Drivers still go to a collection site the same way they always have.
What did DOT’s May 2026 drug testing rule change?
The rule (FR Doc. 2026-09290) took effect June 10, 2026 and made four changes to Part 40:
- Directly observed urine collections fill the oral fluid gap. The 2023 rule required an oral fluid test in a few cases, mainly when a same-sex observer is not available for a directly observed collection. Because no oral fluid labs exist, the new rule says that until oral fluid testing is available, the collector contacts the DER, and the DER either arranges a same-sex observer or sends the driver to another collection site “for a directly observed urine collection” (new §40.67(g)(3)).
- An 18-month grace period once oral fluid arrives. After HHS announces a second certified oral fluid lab, employers get “an 18-month grace period” to keep using directly observed urine collections while they set up oral fluid testing. If an employer is ready earlier, it must use oral fluid in those cases (new §40.67(g)(6)). DOT originally proposed one year and lengthened it after comments.
- Collectors check for a standing order. A new §40.65(d) says that when a new directly observed or oral fluid collection is required, the collector “must check if the employer has a standing order” and, if there is none, “must contact the DER.” Carriers who use a C/TPA should know who answers that call.
- “Gender” becomes “sex” in the observer rules in §§40.67, 40.69 and 40.145, under Executive Order 14168.
DOT said it does “not expect an increase in testing costs as a result of this rule,” because directly observed urine collections already existed before 2023.
What are the 2026 FMCSA random drug testing rates?
50% for drugs and 10% for alcohol, the same as last year. DOT’s random rate page lists FMCSA at 50% and 10% for 2026 and says: “The random rates did not change for 2026… The rate last changed in 2020” (DOT ODAPC, last updated January 15, 2026).
For comparison, the same page lists FAA at 25% drug and 10% alcohol, FTA at 50% and 10%, and PHMSA at 50% for drugs. Carriers that fall under more than one DOT agency can keep covered employees in one pool, per the page’s note. For more on how selections work, see our DOT random testing program.
Is fentanyl part of the DOT drug test in 2026?
Not yet. DOT has proposed adding it, but we found no final rule.
- HHS added fentanyl and norfentanyl to the federal workplace testing panels, effective July 7, 2025 (90 FR 4662). HHS confirmed in March 2026 that it made no further panel changes (91 FR 12308).
- HHS changes reach DOT testing only through DOT’s own rulemaking. DOT has said a change to the HHS analyte table “may affect the DOT testing program under part 40, but only after DOT conducts its own conforming rulemaking” (90 FR 42363).
- On September 2, 2025, DOT proposed adding fentanyl and norfentanyl to its panels. Comments closed October 17, 2025.
A search of the Federal Register on October 14, 2026 for rules touching 49 CFR Part 40 showed no final fentanyl rule. We will update this post when one is published.
What other DOT drug testing notices came out in 2026?
Two more Part 40 documents were published this year. Neither changes what a carrier has to do today:
- March 4, 2026: SAP and return-to-duty reminders. DOT published a notification (91 FR 10518) reminding SAPs to follow the Part 40 return-to-duty procedures and reminding employers of SAP responsibilities. DOT said it had heard that “employers were having a hard time getting the follow-up testing plans from SAPs.” If a driver of yours is in the return-to-duty process, see our Post-SAP program.
- October 1, 2026: a petition on invalid specimens. DOT asked for comments (91 FR 62409) on a petition to add medical verification standards when a driver gives a medical explanation for an abnormal specimen validity result. Comments are open until November 2, 2026. This is a petition, not a proposed rule.
Can drivers still use a paper medical card in 2026?
No, outside Alaska. Land Line reported on October 13, 2026 that “as of Oct. 12, almost all CDL holders are no longer allowed to rely on a paper copy of their medical examiner’s certificate as proof of qualification” (Land Line). FMCSA renewed a one-year exemption only for drivers licensed in Alaska and their employers, which expires October 12, 2027.
This is not a drug testing rule, but it shows up in the same driver file. The medical certification you rely on now is the status on the driver’s CDLIS record. Full details are in our post on the paper medical card exemption ending.
What are the 2026 FMCSA penalties for drug and alcohol violations?
Under the current penalty schedule in 49 CFR Part 386, Appendix B (eCFR, current through October 9, 2026):
- Carriers and other persons: a violation of Part 382, subparts A through F (testing, prohibitions, records, consequences, training), other than a recordkeeping requirement, carries a civil penalty “not to exceed $19,246 for each violation.”
- Drivers: a driver who violates those same subparts faces a civil penalty “not to exceed $4,812.”
- Clearinghouse: “any employer, employee, medical review officer, or service agent who violates any provision of 49 CFR part 382, subpart G” (the Clearinghouse subpart) faces a civil penalty “not to exceed $7,155.”
What should carriers do now?
Most of the 2026 changes keep the status quo. These are the parts of your program to keep current:
- Keep your random program running at 50% and 10%. Make sure every covered driver is in your random pool. Our DOT random testing program runs the pool, sends selection notices and reminds your DER.
- Know who answers when a collector calls. Under the new §40.65(d), a collector who needs a directly observed collection will look for a standing order or call your DER.
- Run Clearinghouse queries on time. 49 CFR 382.701 requires a full pre-employment query before a driver performs safety-sensitive functions and a query “at least once per year” for every driver subject to testing. See our Clearinghouse services.
- Keep each driver qualification file current. That includes the medical certification on the CDLIS record now that paper cards are out. Start with our driver qualification file guide or let us handle it with DQF management.
- Do not plan around oral fluid or fentanyl yet. Neither applies to DOT testing as of October 14, 2026. If either changes, DOT will publish it in the Federal Register.

Frequently Asked Questions
What are the new DOT drug testing requirements for 2026?
The main change is DOT’s May 11, 2026 final rule, effective June 10, 2026. Where a directly observed collection would have to be an oral fluid test, it is done as a directly observed urine collection until oral fluid testing is available. It also gives employers an 18-month grace period after HHS certifies a second oral fluid lab, and it requires collectors to check for an employer standing order or call the DER.
Is DOT oral fluid testing allowed in 2026?
DOT authorized it in 2023, but employers cannot use it until HHS certifies at least two oral fluid labs. As of the HHS list published September 30, 2026, no labs are certified for oral fluid testing.
Did the FMCSA random testing rate change for 2026?
No. FMCSA’s 2026 minimum random rates are 50% for drugs and 10% for alcohol. DOT says the rate last changed in 2020.
Does the DOT drug test include fentanyl in 2026?
Not as of October 14, 2026. HHS added fentanyl to the federal panels in 2025, and DOT proposed adding it in September 2025, but we found no DOT final rule in the Federal Register.
What is the maximum FMCSA fine for a drug and alcohol testing violation in 2026?
Up to $19,246 per violation of Part 382 subparts A through F (other than recordkeeping), up to $4,812 for a driver, and up to $7,155 for a Clearinghouse (subpart G) violation, per 49 CFR Part 386, Appendix B.
