Do you need a post-accident drug test? It depends

Wisconsin Drug Testing Consortium facilitates post-accident drug testing

While it is a safe bet that drivers covered by Federal Motor Carrier Safety Administration (FMCSA) regulations will need a post-accident drug test, that is not the case in every situation. Wisconsin Drug Testing Consortium (WDTC), which offers comprehensive CDL drug test services, assists carriers and owner-operator consortiums with other drug testing services that meet DOT requirements.

The presence of a citation issued as a result of the accident is the primary differentiating point in determining whether or not a driverneeds a post-accident drug test. The following is a breakdown of scenarios detailing when a post-accident drug test must be performed by the employer:

  • Fatality as a result of the accident – Yes, regardless of whether or not a citation was issued to the driver
  • Bodily injury with immediate medical treatment away from the scene – Yes if there was a citation issued; no if there was no citation issued
  • Disabling damage to any motor vehicle requiring tow away – Yes if there was a citation issued; no if there was no citation issued

Other testing scenarios beyond a post-accident drug test

In addition to the post-accident drug test scenarios above, CDL drivers are subject to other tests as mandated by the DOT.

Random – CDL drivers must submit to random testing throughout the year. A self-employed driver must participate as a member of a consortium.

Reasonable suspicion – Drivers who appear to be under the influence of drugs or alcohol are subject to immediate testing.

Return-to-duty – These tests are required for drivers who tested positive, refused or otherwise were in violation of testing requirements. This test is directly observed.

Follow-up – These tests are an extension of the return-to-duty tests and can be extended for up to four years.

While there can be a lot of variables when it comes to determining if a post-accident drug test is needed, WDTC can help make sure you are meeting requirements.
