Drug and alcohol testing is essential after an accident
As a carrier, you have 2 hours to obtain a post-accident drug and alcohol test. If the test cannot be obtained in 2 hours, you have an additional 6 hours to obtain the test but need to document the reasons why the test was delayed. At 8 hours, you should stop attempting to secure a test. Drug and alcohol tests may be required after crashes according to this FMCSA chart.
