Sure Test is a Certified Medical Examiner (CME) and performs DOT physicals in Sioux Falls. These mandated and regulated physical examinations look at your current health status, as well as your medical history, to determine if you are physically fit to drive a commercial motor vehicle. 

Sure Test is certified to perform breath-alcohol testing for clients using Intoximeter, the recognized industry leader in alcohol detection equipment.

When we perform drug tests on individuals, we have the option of sending specimens to labs or providing results in under 5 minutes via a quick screen process.

Sure Test provides hearing evaluations for companies throughout the Sioux Falls region. An audiometer will be used to measure an employee’s hearing to develop a baseline hearing level. Annual rechecks will measure hearing loss caused by workplace noise levels.

A Drug and Alcohol Consortium includes employees from different companies, like owner-operators, subjected to mandated random drug and alcohol testing by the DOT, covering DOT safety-sensitive roles regardless of job titles. Testing is quarterly and evenly spread, with companies able to conduct additional tests as per their policies. Some consortiums extend to non-DOT employees for random testing too.
