Owner-operators: FMCSA says an employer with only one driver subject to testing, such as an owner-operator who is not leased to a carrier, must belong to a consortium for random testing. You cannot pick yourself. A consortium or third-party administrator runs the random pool, the selections and the collections. If you are leased to a carrier, its program covers you.

Clearinghouse: run a full query before a driver first drives, and at least one limited query a year on every driver. Both need the driver's consent, and one consent can cover limited queries for more than a year. If a limited query shows a record, run a full query within 24 hours, or the driver cannot keep driving until you do. Keep the query record for 3 years (49 CFR 382.701).

Post-accident testing required: alcohol as soon as possible. If it is not done within 2 hours, write down why. Stop trying after 8 hours. Test for drugs within 32 hours of a qualifying accident. Pre-employment, return-to-duty and follow-up tests are tracked here but never count toward the random rate. Owner-operators must be enrolled in a random testing consortium.

How often are CDL drivers randomly tested for drugs and alcohol?

Carriers must test a random share of their CDL drivers every year. The current minimum yearly rates are 50 percent of average driver positions for drugs and 10 percent for alcohol. Selections must be spread fairly through the year. The rates did not change for 2026 and last changed in 2020. FMCSA publishes a notice only when it changes them, so check DOT's random testing rates page each January. Testing is also required before a driver starts safety-sensitive work and after certain accidents. It is also required on reasonable suspicion, and for return-to-duty and follow-up.

When DOT drug and alcohol tests are required (49 CFR Part 382)

RandomSelected without warning throughout the yearCurrent minimum annual rates: 50% drug, 10% alcohol (set by FMCSA notice each year)

Frequently Asked Questions - Drug & Alcohol Testing Tracker

What drug and alcohol tests are truck drivers required to take?
Pre-employment testing before your first drive, random testing throughout the year, post-accident testing, reasonable-suspicion testing, and return-to-duty plus follow-up testing after a violation. The minimum random testing rates for 2026 are 50% of the driver pool for drugs and 10% for alcohol, unchanged since 2020. FMCSA publishes a notice only when it changes them, so check each January.
How soon after an accident do I need a drug or alcohol test?
Under 49 CFR 382.303, an alcohol test should be given within 2 hours of the accident, and if it is not, the carrier must write down why. If it is not given within 8 hours, the carrier must stop trying and keep a record of the reason. A drug test should be given within 32 hours. Refusing a required test is treated the same as a failed test, including immediate removal from safety-sensitive duties.
What happens if I fail a DOT drug test?
Immediate removal from safety-sensitive duties, completion of a Substance Abuse Professional (SAP) evaluation and any required treatment, a negative return-to-duty test, and a minimum schedule of follow-up testing over the following months to years. The violation is also reported to the FMCSA Drug and Alcohol Clearinghouse.
How often are random drug and alcohol tests actually done?
FMCSA sets a minimum annual random testing rate that carriers must meet across their driver pool. For 2026 it is 50% for drugs and 10% for alcohol, unchanged since 2020. FMCSA reviews the rates each year and publishes a notice only when it changes them. Random selection means any individual driver could be tested multiple times in a year or not at all, since it's not evenly spread per person.
Does an owner-operator need to be in a random testing pool?
Yes, if you are not leased to a carrier. FMCSA says an employer with only one driver subject to testing must belong to a consortium for random testing. You cannot choose yourself for a test. A consortium or third-party administrator runs the pool and the selections. If you are leased to a motor carrier, that carrier's program covers you.
Does the annual Clearinghouse query need the driver's consent?
Yes. A limited query needs the driver's consent, and one consent can cover limited queries for more than a year. A full query, required before a driver first drives, also needs consent. If a limited query shows a record, you must run a full query within 24 hours. Until then the driver cannot keep driving (49 CFR 382.701).
How long do I keep drug and alcohol testing records?
Five years for positive results, refusals and records of the testing program. Two years for collection records. One year for negative results. Clearinghouse query records are kept 3 years (49 CFR 382.401 and 382.701). Keep them where an auditor can see them fast.
