Types of alcohol and controlled substance tests
Pre-employment: No employer shall allow a driver to perform a safety sensitive function until they have received the negative controlled substance test result.
Post-Accident: As soon as practicable following an accident involving a commercial motor vehicle operating on a public road in commerce, each employer shall test for alcohol and controlled substances each surviving driver: Who was performing safety-sensitive functions with respect to the vehicle, if the accident involved the loss of human life; or Who receives a citation under State or local law for a moving traffic violation arising from the accident, if the accident involved: Bodily injury to any person who, as a result of the injury, immediately receives medical treatment away from the scene of the accident; or One or more motor vehicles incurring disabling damage as a result of the accident, requiring the motor vehicle to be transported away from the scene by a tow truck or other motor vehicle.
Random: Companies are to randomly test drivers at a minimum annual percentage rate of 10% of the number of drivers for alcohol testing, and 50% for controlled substances testing. The random alcohol test must be performed immediately prior, during or immediately after a driver is about to, or has performed a safety sensitive function as defined in Section 382.107. All drivers must have an equal chance of being selected.
Reasonable Suspicion: An employer shall require a driver to submit to an alcohol and/or controlled substance test when the employer has reasonable suspicion to believe that the driver has violated the prohibitions concerning alcohol and/or controlled substances. The employer's determination that reasonable suspicion exists to require the driver to undergo an alcohol and/or controlled substances test must be based on specific, contemporaneous, articulable observations concerning the appearance, behavior, speech or body odors of the driver. The required observations shall be made by a supervisor or company official who is trained in accordance with 382.603.
Return-to-Duty: Each employer shall ensure that before a driver returns to duty requiring the performance of a safety-sensitive function after engaging in conduct prohibited by subpart B of this part concerning alcohol or controlled substances, the driver shall undergo a return-to-duty alcohol test with a result indicating an alcohol concentration of less than 0.02 and/or the driver shall undergo a return-to-duty controlled substances test with a result indicating a verified negative result for controlled substances use.
Follow-up: The Substance Abuse Professional will establish a follow-up testing plan. The employer must ensure that the follow-up testing plan is carried out. A minimum of six tests must be conducted in the first 12 months, and the driver may be subject to this test for a maximum of 60 months.
