What is Controlled Substances and Alcohol Testing (CSAT)?

One of the requirements of obtaining a Motor Carrier Permit (MCP) is to comply with the Controlled Substances and Alcohol Testing (CSAT). If you are an employer, you must identify drivers of commercial vehicles who are using controlled substances, or alcohol while on duty. It is your responsibility to make sure they do not operate a commercial vehicle until they successfully complete a rehabilitation and return-to-duty program, along with follow-up testing for at least a year. If you are an owner operator, it is also mandatory for you to comply with the CSAT.

The testing includes a urine sample for drugs and a breath analysis for alcohol. Circumstances where a test is required:

– pre-employment testing;

– reasonable suspicion testing;

– post-accident testing;

– random testing.

A refusal to submit to testing is a positive test result.

Controlled substances include marijuana, amphetamines, cocaine, opiates and PCP (Phencyclidine). Alcohol, while generally legal, must not be consumed while or within 4 hours prior to driving a commercial vehicle.
