Avoid mixing and matching your safety regulations
The criteria to perform a DOT post-accident drug and alcohol test is similar to — but not the same as — the definition of a crash appearing on your accident register.
If you don’t have a clear understanding of Section 390.5 (Definitions) versus Section 382.303 (DOT post-accident testing), you may find yourself performing tests when you should not. Performing a test under DOT authority when it does not fit within the scope of the regulations is a violation.
