The U.S. Department of Transportation has confirmed that FMCSA’s random drug and alcohol testing rates will remain unchanged for 2026, marking the sixth consecutive year with no adjustments.
For FMCSA‑regulated drivers, the random drug testing rate stays at 50%, while the random alcohol testing rate remains at 10%. Motor carriers must ensure these percentages of their driver pool are randomly tested throughout the year, and drug‑testing consortia must apply the same rates to the operators they serve.
The last time FMCSA modified its random testing rates was in 2020.
