Reasonable suspicion tests
['Drug and Alcohol Testing - DOT']

- Employers may test drivers for drugs or alcohol when a supervisor has reasonable suspicion that the employee is impaired.
After an initial pre-employment test, a driver might not be called upon to take another test for quite some time, if ever. An employee covered by Department of Transportation (DOT) regulations may be selected for a random test, or may need to take a post-accident test at some point during employment.
But what if a driver is suspected of being under the influence of drugs and/or alcohol? What recourse does the employer have? A driver may be tested when a supervisor has reasonable suspicion that the employee is impaired by alcohol or drug use.
