Commercial Driver's License (CDL) Drug & Alcohol Testing

The Office of Risk Management (ORM) manages ISU’s Commercial Driver’s License (CDL) operator alcohol and drug testing program. All departments and their employees in positions requiring a CDL must comply with U.S. Department of Transportation regulations that mandate drug and alcohol testing. Testing is managed by a designated third party administrator, and departments are responsible for test costs.
